Abstract
Practical training is an important component of initial teacher education (ITE). Interactions with the educational reality in schools and with school-based teacher educators (SBTEs) are crucial to practical training. Often, SBTEs lack specific and consistent training to work with future teachers. This study aimed to identify the practices and needs of SBTEs guiding the pedagogical practicum of students, future teachers working in Romanian kindergarten and primary education. A questionnaire provided by the International Forum for Teacher Educator Development (InFo-TED) was administered in December 2021 to January 2022 to 116 SBTEs conducting mentoring activities for future teachers in primary schools and kindergartens. The analysis of their responses by level of education and experience highlighted the perceived usefulness of activity types considered relevant and less relevant in mentoring, training activities previously accessed, professional training needs, and how research is valued in mentoring. Specific training practices and needs are highlighted, providing grounds for developing training programs and interventions aimed at enhancing SBTEs’ competencies in mentoring prospective teachers.

Introduction
The
Despite the acknowledged importance of SBTEs as models and guides for the familiarization of teachers with the teaching profession in real teaching situations, they are insufficiently trained to provide adequate and quality support for future teachers (Clarke & Mena, 2020; Vanassche et al., 2015), leaving them to rely on intuition and their own experiences (Clarke et al., 2014). It is also known that being a SBTE is challenging because it does not have a formal route to follow to teach future teachers (Ping et al., 2021). At the European level, such a situation is recognized, and thus, the policy recommendations draw attention to the need to train SBTE to increase the quality of teacher education (European Commission, 2013, 2015, 2021).
Researchers and training program providers have long ignored SBTEs (Loughran, 2014; Vanassche et al., 2015). However, this situation has changed in the last decade when dedicated research concerns have been noticed (Nesje & Lejonberg, 2022; White & Berry, 2023), and explicative mentoring models and theoretical grounds for advancing professional growth have been elaborated (Kuhn et al., 2022; Kurti, 2023). At the international level, there are dedicated concerns about identifying
Although we identified some studies that sought to identify the training needs of SBTEs, we did not identify studies that focused on the training needs of those responsible for educating future teachers in primary education and kindergarten.
In this article, we aim to portray the training practices and needs of SBTEs mentoring for kindergarten and primary school student teachers in Romania. The data included the types of learning activities considered useful in mentoring, the activities already carried out to enhance their professional competencies in mentoring student teachers in ITE, the issues that should be addressed in future training, and how research is valued as part of their role as SBTEs. Using the same investigative concept and tools as in the InFo-TED survey, we add data gathered in Romania to the international findings. In this way, similarities and differences are pointed out, and patterns of continuing professional development (CPD) in SBTE can be derived.
Theoretical Framework
Learning to teach—in a practical, concrete manner, preparing to become a teacher—is a
SBTEs must fulfill many roles and responsibilities during training activities, from classroom teacher to teacher trainer, researcher, guide/mentor, curriculum specialist, and facilitator, responsible for facilitating students’ understanding of the teaching profession (Murray et al., 2021; White, 2019). Other researchers have differentiated roles as hosts, tour guides to the profession, encouragers, planners, instructional advisors, and teaching partners (Rakes et al., 2023). All these roles lead to different levels of participation in the process of initial practical training, from the minimum level of a teacher who welcomes students into the classroom to the maximum level of a teacher educator (Clarke et al., 2014). Overall, an SBTE is a “dual professional” (White & Berry, 2023), acting simultaneously as a classroom teacher and a SBTE.
To help SBTEs conduct specific mentoring activities, develop specific skills, and cope with multiple roles, specific training programs must be developed based on real and specific needs. Ping et al. (2018) in their literature review on what, how and why teacher educators learn, found that teacher educators
Numerous other opportunities for professional learning and development in informal and non-formal contexts complement dedicated preparation through training programs to become mentors. Whether they exchange experiences and share them with colleagues who are (or are not) part of professional communities of practice at the school level, participate in workshops or other dedicated activities, inform themselves, participate in conferences, or access other training opportunities (Loughran, 2014; Lunenberg et al., 2017), SBTEs can develop their skills to guide future teachers in various ways. Of course, this concern is often not self-evident, unless favorable; sometimes quasi-coercive contexts are created, with conditions and facilities to perform in this role (Lofthouse, 2018). They are often demotivated to perform this role, with no clear responsibilities, facilities, or quality and performance evaluation standards to carry out mentoring activities. The expectancy-value theory (Kuhn et al., 2022) states that most SBTEs voluntarily accept this position, sometimes without compensation, to foster competent prospective educators and share experiences and be open to learning. They sometimes consider it a professional duty to give back, share their expertise, and contribute to enabling future teachers with professional know-how and ethos that allow them to advance their teaching career without dropping out.
Therefore, despite the dissonance they sometimes experience in the role of the SBTE, they feel that they contribute to the professional growth of future colleagues by experiencing their own professional growth (Andreasen, 2023). Some SBTE see the mentoring experience as a way of keeping up with developments in universities and research, both through interacting with university-based practicum coordinators and with students (Andreasen, 2023; Simmie & Lang, 2021). Many SBTEs require additional learning about mentoring (Murray et al., 2021), and such learning can occur according to the ecosystem arrangements of university-school partnerships to conduct practical training in ITE (Andreasen, 2023; Simmie & Lang, 2021). Effective teachers may not necessarily be effective mentors (Evertson & Smithey, 2000); therefore, dedicated efforts and infrastructure should be considered to enhance mentoring competence (Nesje & Lejonberg, 2022). Otherwise, their limitations in performing the mentoring role may disrupt certain mentoring relationships (Hudson & Hudson, 2018).
The specific training to do mentoring activities should focus on things like working together, communicating, building relationships, helping people learn, making the link between theory and practice, helping students with their initial training, and learning how to make decisions based on facts and real-world examples (Ellis et al., 2020; Loughran & Hamilton, 2016; White & Berry, 2023) and the list can go on. Moreover, SBTEs must be experts in making informed decisions, connecting theory and previous research to substantiate their knowledge in the field they teach (Loughran & Hamilton, 2016; MacPhail et al., 2019). Because teaching and research are connected in various ways, the trainers of future teachers must be prepared to critically analyze research in the field to base their teaching on the experiences of the professional community to which they belong to (Loughran, 2014; MacPhail et al., 2019), enabling future teachers’ actions to be evidence-based. However, despite these arguments, SBTEs do not always recognize the need to improve their professional competencies in different regards.
According to the research findings, there are four different types of training needs for SBTEs:
School-Based Teacher Educators in Romania
In Romania, children aged 3 to 6 attend kindergarten, and those aged 6 to 11 attend primary schools. Most teachers who teach in primary education and kindergartens are double-qualified after graduating from the Pedagogy of Primary and Pre-Primary Education (PIPP) BA university program. Teaching practices for future teachers take place in kindergartens and primary elementary schools under the supervision of a
To supervise student teachers’ practicums, schools where SBTEs work collaborate with universities. Universities choose SBTEs primarily based on their academic performance and compliance with some formal requirements, such as holding a second or first teaching degree (the highest level of career advancement). SBTEs often perform this job voluntarily or with very little payment from universities. They cooperate with the university-based practicum coordinator(s), who provide the aims of the practicum activity and have the responsibility to evaluate it, giving marks and related credits, based on the SBTEs feedback. The SBTE, however, provides most of the teaching activity’s content as well as direction and supervision on how to carry it out.
In Romania, there have been concerns about regulating SBTEs activity in ITE for more than 20 years. The Law of education, 1/2011, regulates the mentor as a professional guiding the teaching practice in ITE and professional induction. Meanwhile, there were accredited training courses on mentoring that were accessible to professionals in education as part of their CPD, whether they acted as SBTE or not. Most often, such CPD programs are paid for, and participation depends on the interest and initiative of teachers to follow them. Therefore, it cannot be guaranteed that the SBTE has attended dedicated qualitative training to perform the role of SBTE for the student teacher. Nowadays, the concerns for training the SBTEs as part of integrative approaches to enhance the quality of professional paths and of the teaching career are again under consideration, within the large-scale project “PROF – Professionalization of the teaching career” (2021–2024) coordinated by the Ministry of Education. Therefore, our study adds to such efforts by providing data about the practices and needs of SBTEs for CPD that could be used to improve mentor abilities.
We were interested in identifying to what extent the SBTE in ITE has undertaken dedicated further development activities to enhance their mentoring competence, what kind, what they value more as training opportunities, and what they need to further improve qualitatively as SBTEs.
Research Methodology
The Purpose and Objectives of the Study
Because SBTEs are important for ITE and because they need to be trained to do good mentoring (Loughran, 2014; Vanassche et al., 2015), we did a quantitative descriptive study (Gaciu, 2021), to find out what are the SBTEs training needs. We focused on the SBTEs in charge of training future teachers for primary schools and kindergartens. During their ITE, the students, future teachers, giving their double specializations for both primary and pre-school education, are expected to attend practicum activities both in kindergartens and in primary schools, to an equal extent. They benefit from the guidance of distinct mentors, ones working in kindergarten, and, respectively, in primary schools.
We obtained approval from the coordinators of the International Study InFo-Ted to apply in Romania the investigative tools they developed (Czerniawski et al., 2017). InFo-Ted brings together an international group of specialists from England, Belgium, Ireland, Israel, Holland, Norway, Austria, Australia, and the USA (InFo-TED, 2019) to promote the professional development of teacher educators. Their work aims to develop and implement a knowledge base for teacher educators. Surveys based on the questionnaire commonly developed have been conducted in more than ten countries (Guberman, Macphail, et al., 2021, Guberman, Ulvik, et al., 2021; Murray et al., 2021). As partners in international studies, we can comparatively reflect the training needs of SBTEs in different countries and ensure that the training practices are compatible with those developed in different teacher training systems.
This study aimed to analyze the professional learning needs of SBTEs who carry out training activities for future teachers preparing to work in kindergarten or primary education. Applying the same investigative tool from the InFo-Ted study to the Romanian context, we attempt to answer the following research questions that guided the study:
•(Q1) What types of professional training activities do SBTEs consider useful for mentoring kindergarten and primary education teachers?
•(Q2) What categories of professional training activities did the SBTEs follow?
•(Q3) What issues would SBTEs benefit from training for mentoring students and future teachers?
•(Q4) How do SBTEs value research in mentoring roles?
The answers to the above questions allowed us to obtain a comprehensive picture of SBTEs’ opinions regarding their training needs, since many of them acquire experience after taking on the role of SBTEs (Czerniawski et al., 2017). By pointing out the training undertaken or relevant training activities, as well as by indicating the aspects they feel they will need to be addressed in further training (the perceived needs as gaps of knowledge and competence; Sava, 2012), better tailored training opportunities can be designed, and evidence is provided.
Procedure
The questionnaire provided by InFo-Ted was translated using direct and reverse translation techniques and pre-tested to ensure that it was culturally adequate. To run the study, we obtained the approval of the ethics commission of the university.
The research instrument was conducted online on Google Form, in December 2021, being distributed nation-wide, with the support of the “PROF” project managers, within their network. In January 2022, a questionnaire was sent to all 22 BA programs in PIPP in Romania, with a request to distribute it to SBTEs.
The InFo-Ted study coordinators sent a coding manual with instructions on how to code the data collected through the administration of the questionnaire. The results were analyzed with Jeffreys’s Amazing Statistics Program (JASP Team, 2022), to obtain a descriptive frequency analysis of the data. The University of Amsterdam supports JASP, a free and open-source program for statistical analysis. To determine if there were differences between mentors mentoring in kindergarten and those mentoring in primary education, we used T-tests for independent samples. We also used One-Way ANOVA to analyze whether SBTEs mentoring experience (<6 years, 6–10 years, >10 years of experience in mentoring activities) had any relevance in the selection of useful mentoring activities, in the decision to follow specific training programs, or in getting involved in research activities.
Tool
A questionnaire with 27 questions structured in four dimensions was used. The first-dimension reunited questions regarding the valued professional activities in teacher education (seven questions). Questions like “What professional learning activities would be useful / do you value in assisting you with supporting student and qualified teachers in your school?” were answered on a 7-point Likert scale, ranging from 1 (least value) to 7 (most value). The second dimension is related to the existing and desirable professional learning opportunities. It poses questions like “To what extent would you like to receive further professional learning in the following areas?” with answers on a 7-point Likert scale, ranging from 1 (not at all) to 7 (very much). The third dimension, with questions like “What experience do you have in research / scholarly activities?” and answers differentiated with a 7-point Likert scale from 1 (strongly disagree) to 7 (strongly agree), is meant to create an image of SBTE research practices and interests. The last dimension was dedicated to the participants’ backgrounds in teacher education. In addition, eight were open questions to allow for more specific answers, such as “What are the two most important professional learning opportunities you have experienced so far in relation to your work as a school-based teacher educator?” Moreover, to identify the SBTE mentoring experience, the last part of the questionnaire reunites twelve questions with multiple choice answers, such as “How long you have worked as a school-based teacher educator?” with five options, from 1 to more than 20 years.
For the Romanian version of the instrument, Cronbach’s alpha showed high consistency, with a reliability of .95 for valued professional learning activities, of .90 for the professional learning opportunities, and of .90 for learning associated with research.
Participants
The participants in the study were SBTEs, members in the “PROF” project and collaborators within the practice programs of PIPPs. A total of 116 SBTEs coordinating the pedagogical practice activities of future teachers in primary schools (
Regarding the experience of mentoring for ITE, 48 participants (41.38%) declared less than 6 years of experience in mentoring, 36 (31%) had between 6 and 10 years of experience, and 32 (27,59%) declared experience of more than 10 years in mentoring future teachers for primary education or kindergarten.
Results and Data Analysis
The results presented in the following are grouped around the derived research questions, to point out the professional learning activities considered useful (Q1), the ones already undertaken (Q2), the aspects for which SBTEs would like to receive further training (Q3), and how SBTEs value research as part of their mentoring role (Q4).

The independent sample T-test and One-Way ANOVA revealed that there were no significant differences between the types of professional training activities considered useful in mentoring and that there was no influence of the education level at which the respondents were mentoring (F = 1.409, p > .05). Neither mentoring experience (F (2, 113) = 1.820, p > .01) determines significant differences between the professional learning activities considered useful. However, small differences were observed between the types of activities evaluated as useful for mentoring (Table 2).

Discussion
Improving the quality of ITE is desirable for international and national policies. This raises questions related to the skills and training of SBTEs, teaching professionals from educational institutions responsible for the practical training of students, given their role in fostering the development of practical skills and competencies for prospective teachers. The quality of their guidance is decisive for developing teaching skills and the ethos of the teaching profession. Dedicated training of SBTEs to guide teachers’ pedagogical practice qualitatively is an increasing concern. Such concerns are reflected both in the growing research on the issue (Cochran-Smith et al., 2020; MacPhail et al., 2019; Orland-Barak & Wang, 2021; Ping et al., 2018; White & Berry, 2023) and in the educational policy measures and recommendations formulated and implemented (European Commission, 2021), mainly related to CPD programs for mentoring teachers.
To design training programs tailored to the real needs of SBTEs, it is necessary to identify the training activities they consider useful and the ones they have already carried out, to complement and continue them. In this context, using the investigational concept developed in the international InFo-Ted study regarding the professional development practices and needs of SBTEs, we highlighted, in the present study, data about those in Romania mentoring ITE students for primary education and kindergarten.
Even if a relatively small number of participants responded to the online survey (satisfactory, given the entire population of pedagogical practice mentors from the 22 university undergraduate programs in PIPP in Romania), a picture could be drawn regarding their needs and training opportunities. The data show the SBTEs’ needs throughout the country.
SBTEs shared their openness and concern for improving their skills for mentoring in ITE and perceived as especially valuable the opportunities for professional development (participation in courses, professional discussions, and exchanges of good practices) or personal development (such as self-directed learning). The aspects differentiating the Romanian SBTEs from the international ones (Czerniawski et al., 2017) refer to the type of professional learning activities they prefer to undertake to improve their mentoring skills. Thus, teacher educators from international studies indicate a preference for informal discussions with colleagues and developing their teaching and mentoring skills. In contrast, SBTEs from Romania consider (international) sharing and exchanging experience or participation in certified training courses more useful.
The high preference for
Romanian SBTEs participate in certified training courses and consider them useful. The SBTEs declared themselves satisfied with the existing formal training opportunities. They were interested in self-improvement activities in updating information regarding the mentoring activities they carried out, irrespective of their years of experience in mentoring. This finding might be explained by the fact that the Romanian CPD system requires the accumulation of recognized professional credit points. Therefore, it is a common pattern of CPD not only for SBTEs mentoring at the kindergarten or primary school levels but for all SBTEs, as our data showed (Scorţescu et al., 2023).
However, the SBTEs mentoring for kindergarten, despite having the same pre-service training as the SBTEs mentoring for primary school, indicate less interest in training courses. Such data needs to be contextualized, as they possibly benefited from more certified courses recently, as a large-scale project for improving early childhood education ended in 2021.
The respondents pointed to space for improvement, such as
The commonly expressed training need for research competencies aligns with the initial training of future teachers, which is increasingly grounded in the scientific data of educational research. Empowering teachers to obtain data-informed didactic decision-making requires dedicated solutions. Therefore, covering InFo-Ted and specifically focusing on identifying aspects related to the research skills and needs of SBTEs, as well as aiming to identify and mirror their practices to use the research results in didactic practice, is a novel, timely, pioneering approach to studying SBTEs in Romania. This study captures the relatively limited skills and practices of grounding didactic decisions on research data, a situation similar to SBTEs from Romania and to those from most countries where the InFo-Ted study was conducted (Czerniawski et al., 2017). This aspect requires improving solutions and formative interventions in pre-service and in-service training. SBTEs in Romania show little enthusiasm for participating in research activities, preferring to focus on teaching. Comparable scenarios exist in all nations where the InFo-TED survey has been conducted (Czerniawski et al., 2017). The discrepancy between practitioners and their implementation of research findings, and the need to enhance teaching quality through evidence-based practices, is a key issue to be tackled in the continuous professional development of SBTEs, as highlighted by the European Commission (2021).
In summary, the training needs and practices of Romanian SBTEs do not substantially differ from those of their counterparts in other educational systems. Research competence for data-informed decisions in teaching activities is perceived as a vulnerability by the SBTEs, the ones from Romania indicating this aspect to a larger extent than those from the international study.
Both SBTEs in primary school and kindergarten share certain common elements, but they also exhibit distinguishing factors. The shared elements stem from their initial training and yearly utilization of a standardized national assessment sheet of their professional activities. The disparities identified in the research arise from variations in organizational cultures within their respective workplaces, or variances in the emphasis placed on specific aspects during CPD.
The study has some
Conclusions
The practical component of training future teaching staff is considered relevant to the quality of ITE. SBTE plays an important role in the school–student–university triangle. In this study, we tried to identify and provide data on practices and the self-perceived training needs of SBTEs for improving their mentoring skills.
Overall, the study demonstrates that we cannot discuss an integrated professional profile of the practitioner and researcher SBTEs, like a study by Czerniawski et al. (2017). However, the activities of a teacher and SBTE are to be grounded in empirical findings. Comparing data from Romania with those gathered at the international level, there is an increased need for training in the field of research to conduct mentoring activities; even the SBTEs do not prioritize such needs. Needs for improved research skills can be found in Romanian SBTEs and those from Belgium, Ireland, Israel, the Netherlands, Norway, and Great Britain. The least expressed or conscious need for research skills can be explained from two perspectives. Both the ITE training systems and the activities carried out by the teaching staff in Romania fall short of adequately utilizing these skills.
Summing up the findings, firstly, the
Secondly, the data from the study provide benchmarks for aspects to insist on in CPD training offers, which is of interest to universities concerned with strengthening the quality of ITE while collaborating with well-trained SBTEs. The fact that SBTEs are dedicated to mentoring activities and that they support future teachers even though their training does not entirely meet their expectations necessitates rethinking how they are trained to carry out quality mentoring activities.
Thirdly, while using the data from needs analysis studies, knowing the context of the existing training opportunities undertaken so far is crucial, as otherwise, misleading interpretations might occur. As revealed in the present study, the kindergarten SBTEs seemed less interested in training courses than the ones from primary school, but a possible explanation is that they simply benefited more by such opportunities in the recent past. Additionally, it’s crucial to comprehend the contexts unique to each nation, such as the CPD requirements that shape normative needs, the definition of research activities, related research skills, and so forth.
Fourthly, even if the data provided by the present study are informative for the Romanian context, they complement the international debate and research on SBTEs as a comparative reference for further studies, both regarding the identification of the training needs of SBTEs to perform mentoring activities for future teachers, as well as to share training practices accessed or valued by them as inspiration for their counterparts or training providers.
Improving the quality of ITE and future teachers cannot be imagined without the qualitative guidance of practical activities carried out by SBTEs. Bringing up training needs to offer qualitative mentoring is a restorative endeavor that requires consistent concern and intervention.
There are concerns regarding the training of SBTEs in the Romanian education system. They have begun to be acknowledged and valued in ITE, professional insertion, and CPD. Therefore, this study provides useful data for building tailored training that meets the expressed training needs. Extending the study to a representative sample of SBTEs, once the instrument used proved to be reliable for the Romanian context, can provide more reliable data for further efforts of CPD.
