Educator Preparation Providers (EPP) are challenged to strengthen program assessments through well-constructed rubrics that provide valuable feedback to candidates about their performance and to faculty for making data-supported program decisions. This session will discuss the process for establishing reliability and content validity for planning and student teaching rubrics containing four major constructs related to effective teaching, as aligned to state and EPP's practices of teaching. Judgements from subject-matter experts regarding the relative representativeness of the assessment items in measuring the overarching construct, as well as the importance and clarity of those items was obtained. Results demonstrated evidence towards alignment between assessment content and student learning standards and constructs which the assessments were designed to measure. While this process satisfies accreditation-based technical quality guidelines, participants will also learn how this work provided an increased level of faculty understanding in establishing a more robust assessment system for the EPP overall.
