An Application of Latent Trait Test Methodology to a Large School District Testing Program.
Ridgeway, Gretchen Freiheit
A one-parameter latent trait model was the basis of the test development procedures in the Basic Skills Assessment Program (BSAP) of the Department of Defense Dependents Schools (DoDDS). Several issues are involved in applying the Rasch model to an assessment program in a large school district. Separate sets of skills continua are arranged by difficulty and interrelatedness. An information curve provides an estimate of the error of measurement at each ability level, and the Quality of Measure Index (QMI) is used in the item revision process to estimate curricular relevance and objective-item congruence. Low use of the BSAP results can be attributed to inadequate inservice information, delayed delivery of test results, reporting errors, and difficulties with relating a student to the calibrated curriculum through continua sets. Concepts reflected in the study recommendations include improved training, timeliness, simplicity, and trust. (CM)
