The Young-!-Childrenâ€™s Achievement Testâ€“Second Edition (YCAT-2) is designed to identify-!-young children at risk for school failure. It yields an overall Early-!-Achievement score and individual subtest scores for General Information,-!-Mathematics, Reading, Writing, and Spoken Language. The subtests can be-!-administered independently of each other. All can be transformed to standard-!-scores, percentiles, and age equivalents. -!-
The YCAT-2 was normed on a representative-!-sample of 846 children representing 25 states and 226 different zip codes. Reliability-!-was studied using coefficient alpha, testâ€“retest, and interscorer procedures. The-!-average coefficient alpha for the full normative sample ranges from .85 to .95-!-for the subtests and is .97 for the overall composite.
Extensive validity evidence of the YCAT-2 is-!-provided for content-description validity, criterion-prediction validity, and-!-construct-identification validity. Content-description validity was established-!-through careful selection of items, curricula review, conventional item-!-analysis, as well as an analyses of test floors, ceiling, and item gradients, as-!-well as differential item functioning to limit bias. Criterion-!-prediction-validity was established by (a) correlating YCAT-2 scores with the Woodcock-Johnson III Tests of Achievement-!-(WJ III; Woodcock, McGrew,-!-& Mather, 2001) and Test of Language-!-Development: Primaryâ€“Fifth Edition (TOLD: P-5; Newcomer & Hammill, in-!-development); (b) comparing means and standard deviations between the YCAT-2-!-and criterion tests; and (c) computing sensitivity, specificity, and ROC/AUC-!-statistics. Construct-identification validity was established by studying (a)-!-the relationship of the YCAT-2 to age, reading, language, and intelligence; (b)-!-the ability of the YCAT-2 to differentiate between groups of students known to-!-exhibit below-average academic achievement; and (c) the factorial fit of the-!-subtests to the construct in the test model (i.e., academic achievement).
