The test most similar to the WRAT is the Peabody Individual Achievement Test (PIAT), another short, individually administered test which covers comparable material. In general the WRAT correlates very highly with the PIAT. The WRAT correlates moderately with various IQ tests, in the range of .40 to .70 for most groups and most tests.
Evaluation of WTAR scores across the degree of sustained TBI (mild, moderate, severe) suggests that the assessment may underestimate premorbid IQ in patients with more severe damage. [6] In patients with Alzheimer's disease , WTAR scores declined as the degree of cognitive impairment increased in more affected individuals.
Running at approximately 30 minutes, the WRIT is shorter than traditional IQ tests. The test also involves only four subtests and requires fewer physical materials than a typical test. It was created alongside the Wide Range Achievement Test 3 (WRAT3), [1] [2] a measure of reading comprehension and academic ability, by Pearson Education in 2000.
National Assessment of Educational Progress (NAEP); State achievement tests are standardized tests.These may be required in American public schools for the schools to receive federal funding, according to the US Public Law 107-110 originally passed as Elementary and Secondary Education Act of 1965, and currently authorized as Every Student Succeeds Act in 2015.
The test takes 45–90 minutes to administer depending on the age of the participant. The mean score for the WIAT-II is 100 with a standard deviation of 15, and the scores on the test may range from 40 to 160. 68% of participants in the UK standardisation sample obtained scores of 85-115 and 95% obtained scores of 70-130.
The race-norming in reported GATB individual results did not affect the demographic and statistical validity of the raw, unadjusted GATB scores. In 1990-1991 this practice became more widely known. The public controversy over it resulted in such race-norming of employment testing being explicitly outlawed by the Civil Rights Act of 1991 .
The Wide Range Assessment of Memory and Learning (WRAML), currently in its third edition (WRAML3), is a standardized, individually administered test that measures memory functioning.
(The latter score is doubled so as to compensate for the larger number of items on the first subtest.) Part way through the first passage in the Comprehension subtest, reading rate is also assessed. The primary uses of the Nelson–Denny are as a screening test for reading problems , as a predictor of academic success, and as a measure of ...
