Wide Range Achievement Test 4 (WRAT4)
Description of the WRAT4 The WRAT4 is a norm-referenced test that measures the basic academic skills of word reading, sentence comprehension, spelling, and math computation. It was standardized on a representative national sample of over 3,000 individuals ranging in age from 5-94 years. The normative sample was selected according to a stratified national sampling procedure with proportionate allocation controlled for age, gender, ethnicity, geographic region, and parental/obtained education as an index of socioeconomic status. Alternate forms, designated the Blue Form and the Green Form, were developed and equated during standardization by use of a common-person research design. Derived scores were developed for both age- and grade-referenced groups. Standard scores, percentile ranks, stanines, normal curve equivalents, grade equivalents, and Rasch ability scaled scores are provided. The WRAT4 includes the following four subtests: * Word Reading measures letter and word decoding through letter identification and word recognition. * Sentence Comprehension measures an individual's ability to gain meaning from words and to comprehend ideas and information contained in sentences through the use of a modified cloze technique. * Spelling measures an individual's ability to encode sounds into written form through the use of a dictated spelling format containing both letters and words. * Math Computation measures an individual's ability to perform basic mathematics computations through counting, identifying numbers, solving simple oral problems, and calculating written mathematics problems.
