Abstract
The authors present the development and validation of the Standards Performance Continuum (SPC), a measure for assessing teacher performance of the Standards for Effective Pedagogy. The authors created the SPC to serve as an instrument for research on the relationship between teachers' use of these standards and instructional effectiveness, as a guide for teacher professional development, and as a tool for education reform. The goal of this research was to construct a quantitative instrument that is practical, easily scored, and readily interpretable. The standards are discussed, and 3 studies provide evidence of interrater reliability, concurrent validity, and criterion-related validity supporting the validity of interpretations of data gathered with the SPC.
