Many states are moving away from approaches that base student advancement on credits and "seat time" toward competency-based learning approaches that provide schools with the flexibility to link a student's advancement to mastery of content. Regional Educational Laboratory Northeast & Islands, in partnership with the Northeast College and Career Readiness Research Alliance, has developed a new survey--the Competency-based Learning Survey for Students--to help high schools and school districts collect data on student experiences with competency-based learning. Policymakers and practitioners need this information to improve implementation of and communication about competency-based learning with students. The survey is designed to be administered to students attending high schools in which competency-based learning is being implemented. It collects information on students' beliefs about, exposure to, and understanding of key elements of competency-based learning. These elements include instructional practices that allow students to progress through demonstration of mastery, receive personalized instruction and learning opportunities, demonstrate mastery through flexible assessment, and develop specific skills and dispositions that may be especially critical under competency-based learning. "Developing the Survey" and "Example Figures and Tables" are appended. [This report was produced in collaboration with the Northeast College and Career Readiness Research Alliance.]
