Readiness for school--Testing;
The purpose of this study was to help a local school district in rural Iowa determine the reliability and predictive validity of a Curriculum-Based Measurement Academic Readiness Test (CBM-ART). The subjects were 85 kindergarten students and 77 first grade students enrolled in regular education. The total sample of 162 students was approximately 88% Caucasian, 8% Native American, 2% Hispanic, and 2% Asian. Parallel forms of the test were administered at a 14-day interval, with resulting reliability coefficients ranging from .76 to .94 with a median coefficient of .88. Validity coefficients computed between CBM measures administered in kindergarten and Iowa Tests of Basic Skills (ITBS) subtest measures administered in first grade ranged from -.12 to .66 with a median coefficient of .22.
Forty-four percent (44%) of the total variance of the ITBS Iowa Grade Equivalent Reading score was accounted for by scores on the CBM-ART. An attempt was also made to investigate predictive validity of the CBM-ART using first grade student report card scores, which met with negative results. Conclusions include (a) the CBM-ART was reliable and (b) compared to other instruments employed in the measurement of academic readiness, there was a reasonable degree of predictive validity concerning the CBMART and reading achievement as measured by the ITBS.
