A descriptor for assessments used as a source of evidence for CAEP standards that are created and administered by EPPs directly. They may be in the form of subject or pedagogical content tests, observations, projects, assignments, or surveys. EPPs take responsibility for design, administration, and validation of these assessments. Self-study reports make information available on the purpose and content of each assessment, the scoring, and strategies to investigate data reliability and validity. CAEP reviews are guided by the CAEP Criteria for Evaluation of EPP-Created Assessments. CAEP distinguishes EPP-created assessments fromÊproprietary assessments in which commercial test companies, states, or education research and development organizations design, administer, and validate the assessments.
