A growing body of evidence confirms that good teaching is the most important school-specific factor impacting student achievement and growth. Concerns over teachers’ effectiveness have led to escalating demands for reliable systems that measure teachers’ effectiveness. Such performance systems require a stable and explicit definition of knowledge, skills, actions, and dispositions that comprise the work of teaching. In this chapter, we refer to these as teacher “core competencies” (CCs). Well-defined core competency constructs can anchor investigations of teacher effectiveness for purposes in many different settings, but the field currently lacks a set of common stable descriptors. The descriptors encoded in current standards and assessments are plagued by confusion arising from multiple ideological perspectives, conflicting political views on teacher preparation, and disconnects between stakeholders (e.g., university versus alternative preparation routes).

This chapter presents a study designed to move from descriptive, “input-based” ways to describe teaching to the development and early testing of specific construct descriptors. We begin by distilling many disparate sources of authority regarding what teachers should know and be able to do and assess the validity and usefulness of the resulting descriptors across several measurement applications. We find evidence of stability across multiple populations and different settings and evidence that the constructs can describe preparation program emphases, as well as evidence that some program-level aggregate scores correlate with student assessment scores. We also investigate the stability of competency constructs in different settings, attempting to understand the implications of k-12 school contexts for interpreting core competency measurements of preparation programs.
