An Empirical Comparison of Title I NCE Gains Estimated with Model A1 and with Model A2.
Storlie, Theodore R.; And Others
A comparison is made between Elementary Secondary Education Act Title I normal curve equivalent (NCE) gains derived from the norm-referenced test (NRT) Model A1 and Title I NCE gains derived from the criterion-referenced test (CRT) Model A2. In addition, four equating methods (normalized, curvilinear, linear, and abbreviated equipercentile) for obtaining NCE Title I gains with Model A2 are discussed, and the need for matched samples on both the NRT and CRT required for Model A2 is examined. Data consisted of the Iowa Test of Basic Skills and the Chicago Criterion Referenced Record in Word Attack and Comprehension Skills reading comprehension test results from the 1977-78 Chicago Title I evaluation of students aged 8-11. Correlations between the NRT and CRT were too low (less than .6) to justify equating them. Recommendations were made that a simulation study be designed to investigate the issues addressed in this study. (Author/RL)
