The purpose of this study was to determine the degree to which inter-rater agreement in classroom observation of teachers is affected by using a system where each scale point is defined by a descriptor particularly created for the quality being rated. Thirty-three subjects enrolled in two Teacher Performance Assessment Instruments training…

The plans included in this manual were developed for use in training data collectors to administer the Teacher Performance Assessment Instruments (TPAI). They were designed by classroom teachers and present data collectors with types of plans which might be encountered while assessing teachers in the field. Each set of plans was developed to serve…

This manual was prepared to assist in the development of skills requisite to rating the performance of student or beginning teachers. The activities prescribed in the manual are intended to enable experienced teachers to describe the spectrum of performances indicative of the 18 competencies subsumed in the Teacher Performance Assessment…

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…

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…

This manual consists of lesson plans developed to train data collectors in the use of the Teacher Performance Assessment Instruments (TPAI). Each set of plans was designed for one of three purposes. Lesson plans developed for the Teaching Plans and Materials Instrument (TPM) simulate a portfolio prepared by the teacher. One-day plans developed for…

The Teacher Assessment and Development System (TADS) - Meritorious Teacher Program (MTP) FORM instrument is used in the Dade County Public Schools, Miami, Florida, to evaluate teachers. Its validity for decisions concerning merit pay for master teachers was examined in this study. Specifically, its ability to discriminate between high performing…

The magnitude of simple and multiple correlations between the Teacher Performance Assessment Instruments (TPAI) ratings of elementary student teachers and achievement gains of their pupils is assessed, as well as the impact of certain methodological and contextual factors on the validity coefficients generated. The TPAI is a set of four…

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…
