The migrant program's evaluation system necessitates that instructional personnel evaluate students on a continuing basis using criterion-referenced items that have been developed and validated. This measurement system consists of 230 criterion-referenced items designed to measure 230 objectives in reading and math. These range across seven levels and grades K-6. The study determined whether teachers in the program were able to use the project developed criterion-referenced measurement system to produce valid measures on students. During February 1976, a stratified random sample of students was selected and matched with a group of randomly selected criterion-referenced items from the system. The project staff who developed the system (and on whom inter-rater reliability had been established) visited each school and individually tested the selected students on the selected items. Two measures were noted: the existing teacher rating (taken from student records) and the results of the staff testing. In both cases, teacher and staff ratings were in terms of whether the student did or did not perform satisfactorily on the objective. The resulting data available for analysis consisted of 120 student ratings (teacher and staff) in reading and 130 student ratings (teacher and staff) in mathematics. Findings indicated a high degree of agreement between teacher and staff ratings. (NQ)
