Administration Validity
WRAT4 has strong construct validity because it tests all the aspects it claims to test which are measures of academic achievement and cognitive ability.
This test has overall strong internal consistency reliability. The reliability factors range from .83-.96. Within this range the math is least internally consistent while the reading has the highest internal consistency. Quality of the test Setting

WRAT4 Professional Manual, the WRAT4 Test Forms and Response Form.
Children ages 5 to 7 take about 15 to 25 minutes and the administration time for those individuals age 8 or older into adulthood is between 30 and 45 minutes. The 5/7/10 rule is a unique way of knowing how the participant is doing during the test.
If the person gets the first 5 consecutive questions wrong then you stop and administer preliminary questions which are easier.
If the person gets 7 spelling questions wrong consecutively at the beginning you stop and administer the alphabet test instead.
The "10 rule" applies if someone gets 10 questions wrong then you stop the test. 5/7/10 Rules
