As states across the country continue their implementation of the Teacher Performance Assessment Portfolio (edTPA), a complex and high-stakes certification requirement for teacher certification, there are important lessons for educators and education advocates to learn from New York State's implementation. As Linda Darling-Hammond, developer and…

Much of the responsibility for measuring teacher competency rests with teacher educators. Instead of developing new observation inventories, educators should use available ones. This article describes instruments used at the University of Toledo's competency-based teacher education program since 1979 and suggests they are broad enough to be used…

Describes a competency assessment system developed for use with preservice and inservice teachers and reports the reliability and validity of the instrument. Presents data from a tryout of the assessment system with a group of preservice science teachers. (CS)

The statewide teaching performance assessment instruments being used in Georgia, North Carolina, and Florida were examined. Forty-one reliability and validity studies regarding the instruments in use in each state were collected from state departments and universities. Georgia uses the Georgia Teacher Performance Assessment Instrument. North…

The purpose of this study was to compare the relative magnitude of the variance components and generalizability coefficients derived from the Teacher Performance Assessment Instruments (TPAI) data using two different methods of data collection: (1) occasions when observers were in the classroom for simultaneous observation and (2) occasions when…

An overview is presented of a performance-based assessment system, Teacher Performance Assessment Instruments (TPAI), developed by the Teacher Assessment Project at the University of Georgia to measure competencies of beginning teachers for initial professional certification. To clearly separate the preparation and certification functions within…

The purpose of this study was to compare the scoring of Teacher Performance Assessment Instruments (TPAI) indicators using discrete descriptors when some are considered "essential" with the scoring of these same indicators, and when no descriptors are considered essential. The two questions addressed in this study were: (1) To what…

The influence of day-to-day variation in teacher performance on the reliability and validity of teacher assessment was examined. An attempt was made to identify and quantify sources of score variation attributable to differences in teacher performance, day of observation, observers, and test subscales; and to determine their effects on reliability…

This paper assesses the credibility of a single total instrument score and various logical sub-scores derived from a series of summative judgments about the quality of teaching performance. The objectives were to compare the generalizability of alternative Teacher Performance Assessment Instrument (TPAI) scores, to compare the dependability of…
