- Oral Language (Correct answer)
- Mathematics
- Written Expression
- Basic Reading
Correct answer: Oral Language
The Oral Language domain covers listening comprehension and oral expression.
Question 5: An examiner notes a student scored very high on Math Problem Solving but low on Math Fluency. This pattern most suggests:
- Strong reasoning but slow calculation speed (Correct answer)
- Inability to understand any math
- A reading disability
- A hearing impairment
Correct answer: Strong reasoning but slow calculation speed
Good problem solving with weak fluency suggests reasoning is intact but speed of computation lags.
Question 6: Why might the WIAT be administered as part of an IEP eligibility evaluation?
- To document academic skill levels for special education planning (Correct answer)
- To measure physical health
- To screen for color blindness
- To assess social media use

- The grade level at which a typical student earns that raw score (Correct answer)
- The student's actual enrolled grade
- A pass/fail rating
- The number of items correct
Correct answer: The grade level at which a typical student earns that raw score
A grade equivalent indicates the grade level at which the average student would achieve that score.
