Question 1: On the WRAT5, what does a standard score of 115 indicate?
- Below average performance
- Average performance
- Above average performance (Correct answer)
- Extremely superior performance
Correct answer: Above average performance
A standard score of 115 falls one standard deviation above the mean (100), placing it in the above average range.

- Academic Skills Battery
- Reading Composite
- Basic Reading Composite
- Literacy Composite (Correct answer)
Correct answer: Literacy Composite

Question 3: A student receives a WRAT5 Word Reading grade equivalent of 4.5. What does this mean?
- The student is in 4th grade, 5th month
- The student performs like an average student in the 5th month of 4th grade (Correct answer)
- The student should be placed in 4th grade

- They are not normed on US populations
- They exaggerate differences at extreme score ranges (Correct answer)
- They cannot be used for children under 10
- They only apply to the Math Computation subtest
Correct answer: They exaggerate differences at extreme score ranges
Age equivalents are often misinterpreted and exaggerate score differences at extreme ranges, making them less reliable than standard scores.
Question 5: What confidence interval is typically recommended when reporting WRAT5 standard scores?
- 68%
