The Wide-Range Achievement Test (WRAT) was developed in the 1930s by psychologist Joseph Jastak and first published for operational use in 1946. Two subsequent revisions of the WRAT were issued in 1984 (WRAT-R) and 1993 (WRAT 3; Wilkinson, 1993). The current edition—WRAT 4—retains the focus of the previous editions by providing norm-referenced measures of reading, spelling, and mathematics computation. Designed for use with individuals age 5–94 years, the WRAT 4 contains four subtests: word reading, sentence comprehension, spelling, and mathematics computation. The reading and sentence comprehension tests must be administered individually, whereas the spelling and mathematics computation tests may be administered either individually or in small groups. The administration time required is 15–45 minutes, depending on the age of the test taker. The various editions of the WRAT have enjoyed widespread use due to their ease of administration and scoring and the amount of information obtained in a relatively brief amount of testing time.
