Abstract
The assessment of ‘swimming’ in the context of preventing drowning is complex. Programs may/may not emphasize water safety, survival or aquatic competency. Therefore, establishing content validity of any assessment tool is an essential first step for a more consistent approach for assessments in learn-to-swim. The content validity of the RAEE (Refuse, Assist, Effective, Efficient) assessment tool was investigated using AUSTSWIM experts (n = 23) as participants, the Australian Water Safety Council's benchmark program and a cross-sectional questionnaire on demographics and evaluation of relevance and usefulness of the RAEE assessment tool in assessing these aquatic skills. Opinions from industry standard experts supported the content validity of the RAEE assessment tool for use in assessing the benchmark level for swimming and water safety, finding it relevant (77%±8) and useful (73%±5). A range of issues requiring ongoing research were highlighted, including communication (terminology surrounding swimming and water safety), assessment (pedagogical approach, program design/use, assessment methods/tools), and raters knowledge and understanding of water safety skills. There is an apparent disconnect between awareness of water safety (expert awareness of the Australian Water Safety Council 96%) and how that is translated into practical knowledge and understanding, regardless of the program being taught. Increasing the usage and knowledge of valid and reliable assessment tools can potentially help establish the link between drowning prevention and the aquatic skills, knowledge and understanding are required in an aquatic environment.
Introduction
The World Health Organisation (WHO) guided by research into global drowning prevention has identified swimming, water safety and self-rescue skills, knowledge and understanding (collectively to be referred to as aquatic skills) to be key factor in drowning prevention.1–3 Following the 2016 National Water Safety Education Competency Framework, an integral part of Australia's Water Safety Strategy (AWSC), it is recommended for learn-to-swim programs to ensure that all children within their programs attain a benchmark level of age appropriate aquatic skills. 2 The instruction and assessment of aquatic skills (aspects of the more holistic construct of aquatic competency), is mostly conducted within learn-to-swim programs, delivered nationally by a range of independent commercial and school-based providers.4–7 The range of learn-to-swim providers makes it difficult to establish the overall effectiveness of any particular program in meeting the goals of AWSC as the aquatic skills taught and assessed by each school varies. 8
The lack of a consistent approach across learn-to-swim providers may in part stem from the term ‘swimming and water safety’, terminology intended to emphasize the importance of including water safety in lessons.9,10 This term refers to the separate elements of swimming, in the sense of a physical motor action performed to propel one's body through the water and to a series of more safety-oriented actions (and the associated knowledge) required to successfully interact in various aquatic environments. 3 This general term of ‘swimming and water safety’ is open for interpretation in relation to what specific skills should be included in the design and delivery of swim programs, with different perspectives prevalent within the industry, about which are most essential in drowning prevention.6,11 In addition to the lack of consensus about what aquatic skills should be taught within a learn-to-swim program, it also remains unclear which of those aquatic skills should be assessed, and how this should be accomplished.4,12 This is exacerbated by a lack of recognized tools to assess these aquatic skills.6,8,13,14 While assessment tools have been developed for specific aquatic programs (e.g., assessment for students with disabilities and infants/pre-schoolers), their recognition and general use across the mainstream learn-to-swim industry is limited.6,15 #3728
The term ‘swimming’, is frequently used in a colloquial sense to denote any grouping of aquatic skills needed within the ‘learn-to-swim’ industry, which may or may not emphasize water safety and survival skills or the broader notion of aquatic competency.7,12,16 Establishing a valid tool to assess the attainment of aquatic skills requires differentiating between assessing ‘swimming’ skills and the more general water safety and self-rescue skills. 17 This is because the intent of application for specific aquatic skills and knowledge such as for competition, recreation and/or survival interacts with the interpretation of relevant assessment criteria. Such ambiguity about what it means to be proficient at ‘swimming’, confounds attempts to establish valid and reliable assessments. 6 a problem acknowledged by various sources.18–22
Existing aquatic skills assessment methods have evolved from physical education practices in general.4,23–25 Formal assessments of movement skills in physical education are considered time consuming, of little value and usually include only a dichotomous nominal scale assessment methods, a situation that is echoed in learn-to-swim. 26 However, in an aquatic environment, where the goal is water safety, survival and drowning prevention, a dichotomous scale that identifies whether someone can or cannot accomplish a specific skill, might not appropriately indicate the extent of skill acquisition. Nor can it accommodate the situational context of the aquatic skill performance. This refers to the variety of environmental factors such as changes to water depth, water temperature or current, 27 which can potentially change the outcome of an individual's assessed performance from seemingly ‘expert’ to ‘only just’ or ‘cannot’.28,29 Given assessment outcomes for aquatic skills are used as an indicator of personal safety, an assessment approach that lacks the ability to differentiate discrepancies across conditions in proficiency is not ideal.2,12 There is a need for assessment tools that are specific to learn-to-swim, designed to incorporate evidence-based measurement approaches that acknowledge and address these limitations.
One approach to address the limitations of aquatic skill assessments is to incorporate an ordinal scale, which allows for the qualitative aspects of the movement patterns being assessed to be identified and corrected (i.e., process oriented assessment).30–32 This would better relate to the ultimate intended outcome of attaining aquatic skills. Prevention of drowning is complex and includes the ability to recognize and understand interactions (both intentional and unintentional) with water and how to apply appropriate actions and decision making to mitigate potential risks in an aquatic environment. 16 This goes beyond the ability to swim using a recognized stroke in a controlled environment, and it is these type of actions in an aquatic environment that needs to be included in ‘learn-to-swim’ assessments if they are to be valid strategy in the prevention of drowning.3,19,33,34 In addition to requiring a focus on the qualitative aspects of the skills being measured, valid assessments should align with the goals of the program (i.e., which combination of swimming, water safety and self-rescue skills were used and with what intent). In response to these identified needs, a process oriented, ordinal scale assessment tool, referred to as RAEE (Refuse, Assist, Effective, Efficient; Table 1), 35 that used the Australian Water Safety Council's benchmark program – Royal Life Saving Society Australia (RLSSA) Swim & Survive (level - Active Award 4–2016 version), was developed. We have established the face validity of the RAEE as a useful tool to implement in aquatic skills assessment. 35
Assessment tool – RAEE (refuse, assisted, effective, efficient). The RAEE is designed to apply to movement skills, water safety knowledge and understanding with the rating system broadly broken into four main areas: Refusal – Assisted – Effective – Efficient.
Establishing content validity of a movement assessment tool is commonly achieved through exploring the opinions of experts. 36 An expert panel is the simplest and most direct method in this respect and provides a means for gauging whether an assessment tool is an accurate reflection of the content the tool is meant to measure. For this content validity study, the organization recognized as providing the national industry standard for training swim instructors was incorporated. The Australian Council for the Teaching of Swimming and Water Safety (AUSTSWIM), is a national governing body including representatives of swim, surf and water safety organizations from all states and territories of Australia. 4 AUSTSWIM is internationally recognized as the first aquatic education organization in the world to be accredited for how teachers are trained, accredited and licensed (ISO/IEC 17024), and therefore recognized as industry leaders in learn-to-swim. 37
This study aimed to explore the opinions of a panel of AUSTSWIM trainers, known as ‘presenters’ within the industry, to establish the content validity of the newly developed nominal, process-oriented assessment tool RAEE, in assessing the ‘must see’ criteria of skills in the RLSSA Swim & Survive (Active Award 4–2016 Version).
Method
Participants
Establishing the content validity of this assessment tool is an important first step to bring a more consistent approach for aquatic skills assessment to the learn-to-swim industry. Specifically developing a valid tool to assess the full range of aquatic competencies necessary to aid with drowning prevention. Therefore, a panel of experts in aquatic competencies (n = 23) were recruited from a cohort of AUSTSWIM presenters attending one of two professional development workshops at the ‘Soak it up 19’ AUSTSWIM State Conferences in New South Wales and Western Australia. An AUSTSWIM Presenter (also known as a ‘trainer’) is an accredited AUSTSWIM teacher who has undertaken further training to meet accreditation requirements to deliver the knowledge and skills in the delivery and assessment of the AUSTSWIM Teacher of Swimming and Water Safety™ course. Participant information sheet and consent forms were sent via email by the AUSTSWIM conference organizers to the registered participants prior to the workshop and re-distributed in hard copy at each workshop to obtain consent form prior to commencement of the questionnaire.
Protocol
A cross-sectional questionnaire approved by The University of Newcastle Human Research Ethics Committee (H-2019-0069) was disseminated to a cohort of AUSTSWIM presenters recruited. These paper-based aquatic skill questionnaire included two main sections and included questions 1) relating to demographics and background, and 2) questions designed to evaluate the relevance and usefulness of the RAEE assessment tool in assessing the ‘must see’ criteria of the RLSSA Swim & Survive Active Award 4. The AUSTSWIM experts watched a video compilation of Active Award 4 skills being performed prior to answering the relevance and usefulness questions. When summarizing the results to establish content validity a criterion level needs to be established. 38 In this case, agreement from 7 out of 10 experts (70%) was recognized as the minimum level of agreement amongst the experts in order to find the assessment tool to be valid. 38
Aquatic skill questionnaire
The paper-based aquatic skill questionnaire included two main sections. Section one involved demographic and presenter background questions that were divided into four categories: 1) basic information of age, sex, years of experience; 2) information about experience relating to teaching environments, including programs and assessment methods utilized; 3) Information about qualifications, the maintenance of currency and awareness of benchmark criteria; and 4) awareness of the AWSC, benchmark and associated programs/skills.
The second section of the questionnaire offered a series of questions asking each participant's opinion of the RAEE assessment tool. This section included a color coded table that presented the RAEE Assessment tool including the criteria for use of the aquatic skills tool (Table 1). The questions response options in this section were a three-point Likert scale (not relevant, neutral, relevant) and presented against an itemized list of each ‘must see’ criteria from the RLSSA Swim & Survive Active Award 4 Assessment guide. Participants were asked to rate how relevant the RAEE assessment tool was for assessing each criterion, using the Likert scale, then to repeat the same rating process to gauge how useful the RAEE was for assessing each criterion.
Procedures
After completing the first two sections of the questionnaire, participants were given five minutes to review the RAEE assessment tool material provided and had any queries answered, prior to viewing the video compilation. The participants then viewed, as a group, the three-minute video compilation that demonstrated the performance of all 14 aquatic skills from the RLSSA Swim and Survive: Active Award 4. After viewing the video clips, participants completed the third section of the questionnaire that related to the relevance of the RAEE tool. Following this, the same video compilation was re-played before participants completed the final section of the questionnaire relating to usefulness of the tool. All completed questionnaires were then collected.
Video clip compilation
The video recording of the 14 RLSSA Swim & Survive Active Award 4 aquatic skills shown to the panel included adult volunteers filmed completing these aquatic skills in a 50 m heated pool as part of a larger study (H-2015-0272). These swimmers (n = 28) were aged between 18 and 34 years (self-reported) and were assessed by a licensed AUSTSWIM trainer as competent swimmers. Each aquatic skill performance was filmed using a hand-held video camera (Neos Wi-Fi Model No: HN-TOP1). All skills were performed in accordance with RLSSA Swim & Survive Active Award 4, with the exception of modifications to clothing worn (long- sleeved shirt, long sleeved jumper and long pants) and exit (into an inflatable boat). The video of each aquatic skill was edited to approximately 10 s and a 3-min compilation video of these skills was created. 39
Analysis
The questionnaire data were collated and imported into SPSS (IBM Corp. Released 2017. IBM SPSS Statistics for Windows, Version 25.0. Armonk, NY: IBM Corp) and descriptive statistics calculated for all demographic questions. Any unanswered questions were allocated to ‘no answer’ and included in the descriptive statistics. In addition, percentage agreement was calculated for the question relating to the usefulness and relevance of the RAEE, and the criterion for the minimum level of agreement in order to find the assessment tool to be valid set at 7 out of 10 experts (70%). 38
Results
Demographics
Twenty-three participants (n = 20 female, n = 3 male), with a median age group of 45–54 years consented to be involved in the study (Table 2). Almost half (48%, n = 11) of participants had held an AUSTSWIM qualification for more than 20 years, and a further quarter for between 15–20 years (26%, n = 6). All participants were AUSTSWIM qualified as Teachers of Swimming and Water Safety, with approximately three-quarters of experts also being qualified to teach Infants and Preschool (78%, n = 18), Presenters (74%, n = 17), and Access and Inclusion (70%, n = 16). Maintaining currency of qualification was achieved mostly by attendance of state conferences (87%, n = 20) and professional development workshops (87%, n = 20).
Participant demographics.
Most participants worked with commercial swim schools employing more than six instructors (78%, n = 18), followed by school-based swim schools (70%, n = 16; Table 3). Individually designed programs run by swim schools were the most commonly reported program (57%, n = 13), followed by school-based swim schools, Swim and Survive programs (39%, n = 9) and individually designed programs (35%, n = 8). The assessment approach undertaken to identify the appropriate placement into a learn-to-swim program, for both new students and for progression within an existing program, was primarily conducted informally by an individual instructor (83%; 78%) or single assessor (74%, 57%), respectively.
Program demographics.
* - Number of staff employed in Commercial Swim School.
Almost all participants were aware of the existence of the AWSC (96%, n = 22), however only just over half were aware of the benchmark (61%, n = 14; Table 4). While nearly three quarters of the participants used the Swim and Survive program (74%, n = 17), only just over half used the assessment guide included within this program (52%, n = 12). Even fewer participants (48%, n = 11) reported being familiar with all aquatic skills included within the Swim and Survive program.
Awareness and use of benchmark.
Relevance
Each ‘must see’ criteria of RLSSA Swim and Survive: Active Award 4, as listed in the accompanying assessment guide to this program, was ranked on a Likert scale. When responding to questions about the relevance of the RAEE for each of the listed items, over three quarters of participants (77% ± 8 SD) found the tool to be relevant across all items (Table 5). However, the individual levels of agreement dropped below the 70% criterion level 38 for three items (one from sculling and body orientation and two from survival and personal flotation device skills). When responses were considered according to the experts’ use of the RLSSA Swim and Survive program in practice, the relevant response increased to a 71% amongst those who actually used the program.

Usefulness
Usefulness of the RAEE was determined by selecting from a scale of useful, neutral, or not useful against the same ‘must see’ criteria. The responses for how useful the RAEE assessment tool was similar to its relevance findings, with just under three quarters of participants finding the tool to be useful (73% ± 5 SD). There was an increase in ‘no answer’ (11%) responses, as well as three items that didn’t meet the 70% criterion level (two from entry and exit skills, and one from survival and personal flotation device skills). Again, when use of the program was taken into account, all but one item reached a minimum of 71% agreement that the RAEE tool was useful. The only item that did not meet the criterion, regardless of use of the RLSS Swim and Survive program was part of the survival and personal flotation device skills (change stroke after every minute).
Discussion
This study explored the content validity of the newly developed RAEE aquatic skills assessment tool. Establishing a valid aquatic skill assessment tool specific to the learn-to-swim industry is important given the need to ensure the aquatic skills assessments being conducted are not only an accurate reflection of the intended content, but also relate to the proposed outcome of drowning prevention. 6 Expert opinion from industry standard experts (i.e., AUSTSWIM trainers) was sought in this content validity study and the results indicated that the RAEE aquatic skills assessment tool met the criterion level agreement for the overall items for both relevance and usefulness, with 77% and 73% respectively. This would indicate that this aquatic skill assessment tool is valid for both face validity 35 and content validity (relevant and useful) in this study when assessing the aquatic skills with the RLSSA Swim and Survive – Active Award 4.
It was identified that assessments of aquatic skills within the learn-to-swim industry are based most frequently on subjective opinion based on the raters’ observation. The validity of a subjective qualitative assessment is often criticized as it is susceptible to being prone to personal bias, not being judged against well-defined criteria, and/or not being recorded. 40 This study found variability between individuals in levels of agreement for relevance for the individual assessment items (grouped into eight sub-sets of similar skills) suggesting subjective bias.
Specifically, the results within the sub-sets illustrated a disparity between the levels of agreement for items assessing swimming skills (movement and swimming strokes, 90% agreement as relevant) when compared with the survival and water safety skills (survival and personal flotation device skills, 71% agreement as relevant). It is likely that this disparity in the opinions about the relevance of using a tool to assess these skills reflect a bias towards teaching locomotive and specific swimming strokes rather than the full range of aquatic skills (including survival and personal flotation device skills) in the learn-to-swim industry. 7 In Australia, up to 80% of swim schools do not provide essential water safety and survival oriented aquatic skills and knowledge in their programs, and are more likely to teach swimming skills (e.g., freestyle 87%, backstroke 83%) than water safety skills (e.g., treading water 53%, survival backstroke 46%). 7 The lower reported level of agreement for the relevance of the RAEE for assessing survival skills may be indicative of either a lack of familiarity with water safety skills in general and/or the specifically defined assessment criteria. This is supported by the demographic results that showed less than half of the experts were familiar with all of the skills of the Swim and Survive program (47%), which specifically incorporates water safety and self-rescue items.
The usefulness of the RAEE assessment tool when considering the level of agreement for each of the subsets, showed that 79% identified it was useful for movement and swimming strokes and 69% for survival and personal flotation device skills. The level of agreement for survival and personal flotation device skills was similar to the findings relating to the relevance of the RAEE, with the exception of movement and swimming strokes where 79% indicated it was useful yet 90% indicated it was relevant. As the majority of swim schools have a focus on teaching swimming strokes over water safety or survival skills, these results may reflect a greater familiarity for teaching and assessing these skills amongst instructors.7,12 A possible explanation for rating the usefulness of the RAEE lower for the movement and swimming strokes could, as with the findings for relevance, be the higher level of familiarity with these items compared to familiarity of the survival and self-rescue items. This is supported by the demographic results that indicate less than half (48%) were familiar with all of the Swim and Survive tasks. There is an apparent disconnect between awareness of water safety (expert awareness of the Australian Water Safety Council 96%) and how that is translated into practical knowledge and understanding, regardless whether the program taught is private, swim or school based. This disconnect warrants further investigation as there appears to be multiple aspects regarding the teaching of water safety skills that could be impacted. Aspects such as the adequacy of existing training and ongoing support within the aquatics industry, the inconsistent inclusion within learn-to-swim programs, as well as the lack of familiarity amongst teachers of swimming and water safety.
Practical findings for swim instructor educators
The minimum standard of skills attainable for all Australian children is the AWSC's 2016 benchmark level of swimming and water safety. In the aquatic industry there is a general lack of consensus relating to what constitutes proficiency in performing these aquatic skills,21,35 inconsistency to communicate outcomes accurately as well as in assessment practices 35 ; a finding reaffirmed by this current study. For swim instructor educators it is important to ensure that their knowledge and understanding of aquatic skills are consistent with other fellow swim instructors and/or swim school(s) they work with by maintaining clear communication in teaching and assessment. To do this, the RAEE offers swim instructor educators a valid framework to better communicate assessment outcomes, which is likely beneficial to both other swim instructors and parents.
Conclusion
While the results of this study supported the content validity of the RAEE assessment tool for use in assessing the benchmark level for swimming and water safety, it has highlighted a range of issues requiring ongoing research. These issues include communication (terminology surrounding swimming and water safety), assessment (pedagogical approach, program design/use, assessment methods/tools) as well as knowledge and understanding of aquatic skills, specifically those relating to water safety skills amongst AUSTSWIM trainers. This exploration into the content validity of an assessment tool for swimming and water safety highlights the need for valid and reliable assessments within the learn-to-swim industry. Increasing the usage and knowledge of valid and reliable assessment tools can potentially help establish the link between drowning prevention and the skills, knowledge and understanding are required in an aquatic environment.
