The goal of this study was to provide normative scores and examine the psychometric properties of the Math Computation subtest of the Wide Range Achievement Test--IV (WRAT-IV) for Mexican adolescents after the completion of junior high school. We group-administered this subtest to 1,318 first-year Mexican high school students. We then obtained its…

To understand mathematics, children must interpret mathematics symbols. In this study, we designed a brief assessment of mathematics symbols for children in the elementary grades. For each of 23 symbols, children identified the symbol, provided the meaning of the symbol, and used the symbol. We assessed 297 children in Grades 1, 3, and 5. Internal…

The purpose of this study is to construct and evaluate diagnostic battery tests of verbal and non-verbal learning disabilities for students in the Arabic schools. 612 students were in the 3rd, 4th and 5th grades of primary school were involved, mostly from Egypt and Saudi Arabia. Their ages ranged from 7.94-10.98 with mean age = 9.62 and SD =…

This guide is designed to assist States, agencies, and/or facilities who work with youth who are neglected, delinquent, or at-risk (N or D). The information in the guide will benefit those who are (a) interested in implementing pre-posttests, (b) in the process of identifying an appropriate pre-posttest, or (c) ready to evaluate current testing…

Math anxiety has been historically overlooked in samples of children. This may be due in part to the lack of appropriate tools to measure anxiety in young children. The current exploratory study reports on the development and examination of reliability, validity, and factor structure of a new tool to measure math anxiety in young children. The…

Although there are a number of standardised measures to assess dyslexia in children, there are comparatively fewer instruments suitable for the assessment of dyslexia in adults. Given the growing number of students entering UK higher education institutions, there is a need to develop reliable tools for assessing the additional needs of those with…

The Working Memory Rating Scale (WMRS) was designed as a behavioral rating tool to assist teachers in identifying students at risk of working memory difficulties. The instrument was originally normed on 417 monolingual English-speaking children from the United Kingdom. The purpose of this study was to test the reliability and validity of the WMRS…

The technical characteristics of scores on the Reading Essential Skills Screener-Upper Elementary Version (B. T. Erford, G. Vitali, R. Hass. & R. R. Boykin, 1995) were studied using 4 independent samples of boys and girls in Grades 4-6. Decision efficiency, principal axis factor analysis, internal consistency, 30-day test-retest reliability,…

The Slosson-Diagnostic Math Screener (S-DMS) was designed to help identify students in Grades 1 to 8 at risk for mathematics failure. Internal consistency, test-retest reliability, item analysis, decision efficiency, convergent validity, and factorial validity of all five levels of the S-DMS were studied using 20 independent samples of students…

The Wide Range Achievement Test-Revised and the Woodcock Reading Mastery Tests-Revised were administered twice to 269 current drug abusers over an average time interval of 204.2 days. Overall, the study demonstrates that the two instruments have strong psychometric properties and that results from current drug abusers are reliable. (SLD)

This study investigated the test-retest reliability and consistency over time of level 1 of the WRAT (for ages 5 to 12) for two time intervals, 2 weeks and 22 weeks. (Author)

This study investigated the efficacy of predicting academic achievement as measured by the Wide Range Achievement Test, using the Slosson Intelligence Test For Children and Adults as the predictor. Results indicate that the Slosson IQ significantly predicts Wide Range standard scores. (Author)

A comparison was made of the results of two locator tests, the Zip Test (ZT) and the Wide Range Achievement Test (WRAT), which were administered to 37 black migrant and resident pupils. The children were tested twice with each test: in early September and eight weeks after in November. Twenty-three children were taught by the Inquiry Method…

A study with Mexican-American children showed the internal consistency reliability coefficients for the Wide Range Achievement Test (WRAT) were high and comparable to those reported in the WRAT manual. A high relationship was found between WRAT and Metropolitan Achievement Test scores. WRAT meets reliability and validity requirements with Mexican…

A comparison of reading subtests of the Wide Range Achievement Test, Peabody Individual Achievement Test, and Slosson Oral Reading Test showed a high correlation between the WRAT and PIAT. Suggests the WRAT and PIAT measure the same dimension of reading achievement, possibly verbal fluency. (Author/JAC)
