Background: School counselors are increasingly expected to engage in data-informed practices to design and deliver effective, evidence-based programs. The Evidence-Based School Counseling (EBSC) model emphasizes identifying student needs through data, implementing empirically supported interventions, and evaluating outcomes. Although existing sources of data can help school counselors identify trends, highlight opportunity gaps, and guide program and intervention planning, surveys are a valuable tool for collecting input from students, caregivers, and educators in their school communities. However, little direction exists on how school counselors can design and administer surveys ethically and effectively in K–12 settings. Framework for Survey Use in School Counseling: This conceptual article addresses that gap by offering research-informed guidelines for survey development. It specifies seven key steps for school counselors to efficiently use or develop effective surveys: (a) Define constructs, (b) define sample and demographic variables, (c) review potential existing scales, (d) write items and response scales, (e) write instructions, (f) choose format and timing of administration, and (g) pilot and finalize. Practice and Training Implications: Through this practical guidance, school counselors can be better prepared to collect meaningful data to support EBSC practices and provide responsive, comprehensive, and student-centered programs. A greater emphasis on survey design can also prepare trainees to enter the profession with the knowledge and skills necessary to engage in data-informed program development. Overall, the ability to use, design, and deliver surveys effectively and ethically is a professional competency that can be cultivated across school counseling practice and training.
