An Evaluation of a Multiple Matrix Sampling Procedure for a State Assessment Program.

Pennsylvania's Educational Quality Assessment Program provides each participating school with a building level Deport in which state percentiles are a prominent part. Multiple matrix sampling was being coL:idered as a technique to reduce testing time. However, there was great concern that the error associated with estimating thel school mean might lead to markedly different percentiles than obtained by census testing. Generally favorable results are reported from a post mortem simulation of multiple matrix sampling for a 2 to 6 subtest/subgroup sampling plan involving data obtained from over 30,000 students in 500 elementary schools.
