Generalizability of Large-Scale Performance Assessments in Science: Promises and Problems.

Gao, Xiaohong; And Others

Applied Measurement in Education, v7 n4 p323-42 1994

This study provides empirical evidence about the sampling variability and generalizability (reliability) of a statewide performance assessment for grade six. Results for 600 students at individual and school levels indicate that task-sampling variability was the major source of measurement error. Rater-sampling variability was negligible. (SLD)
