descriptors offer a narrative understanding of the student's academic abilities. Key
purposes of qualitative descriptors include: - Communicating complex assessment results
in an understandable manner. - Identifying areas of strength and weakness. - Guiding
instructional planning and intervention. - Facilitating parent and stakeholder
understanding during report discussions. ---
Standard Scores and Their Corresponding Qualitative Descriptors
WIAT-III reports typically include standard scores with a mean of 100 and a standard
deviation of 15. These scores classify student performance into categories such as
average, below average, or above average. Common qualitative descriptors for standard
scores include: - Very Superior (130 and above): Significantly above average; exceptional
performance. - Superior (120–129): Well above average; strong skills. - High Average
(110–119): Slightly above average; solid skills. - Average (90–109): Typical range;
expected performance. - Low Average (80–89): Slightly below average; some difficulties. -
Borderline (70–79): Significantly below average; notable weaknesses. - Extremely Low
(below 70): Severe difficulties; significant impairment. Interpretation tip: These descriptors
help identify whether a student's skills are within the typical range or indicative of a
learning difficulty or exceptional ability. ---
