Core-Selective Evaluation Process
Meaningful Evaluations.
Defensible Decisions.
Better Outcomes for Students.
C-SEP helps evaluation teams move beyond simply administering tests to conducting purposeful, evidence-driven investigations of how students learn.
Evaluation with purpose.
The Core-Selective Evaluation Process (C-SEP) is a comprehensive framework for conducting meaningful, student-centered educational evaluations, introduced in 2015.
Rather than relying on a one-size-fits-all approach, C-SEP guides multidisciplinary teams through a systematic process: gathering relevant learning data, developing evidence-based hypotheses, selecting assessments with purpose, and integrating multiple sources of information to answer referral questions and support defensible eligibility decisions.
A clear process for complex evaluations.
