The WRAT-Expanded is a brief achievement instrument that provides an overall assessment of the general skill level of classroom students.

- The WRAT-Expanded provides both individually and group administered forms, which have been co-normed to enable direct comparisons between the two forms.

- The Group (Form G) and the Individual (Form I) forms may be given three months apart allowing for short term pre-test and post-test assessment.

- The Group form may be administered by classroom teachers to screen the entire class at the beginning of the year, taking only three class periods, a maximum 40 minutes each period.

- The Group form may be used by learning specialists (Resource Room teachers, Special Education teachers) to quickly evaluate small groups of referrals, rather than assessing each one individually.

- The Group form provides a nonverbal reasoning component, which gives an assessment of reasoning ability, factoring out language handicaps which might be interfering with school achievement. The Group form also provides content skill analysis for both the Reading and Mathematics tests.

- On the Individual form, recommended test Levels and the "Level Scoring Rule" allow for assessment using a minimal number of items, thus saving time.

- Tables provide age and grade norms, as well as "out of level" norms for students who have been retained a grade, or classes being instructed below grade level.

- WRAT-Expanded was normed on ages 5-24 years, covering college students who might be having learning difficulties.

- Grade levels for the Group form are color coded for easy identification.

Level 1 is for age 7 years
Level 2 is for ages 8-9 years
Level 3 is for ages 10-11 years
Level 4 is for ages 12-14 years
Level 5 is for ages 15-17 years
