Powers, Stephen; And Others
Journal of Educational Measurement, v20 n3 p299-302 Fall 1983
The validity of the equipercentile hypothesis of the Title I Evaluation and Reporting System norm-referenced evaluation model was examined using 3,224 seventh- and ninth-grade students. Findings from confidence interval procedures contradicted the equipercentile hypothesis. There was a pattern of large gains for students not receiving any special educational instruction. (Author/PN)
