IDAT Evaluation and Results 2

Question 1

On the IDAT, which score report component helps admissions committees distinguish between students who performed similarly on the overall exam?

Accepted Answer

Subscale scores by domain

Answer

Subscale scores break performance into specific domains, allowing committees to differentiate candidates with similar total scores.

Question 2

A student's IDAT result shows a stanine of 5. What does this indicate about their performance?

Accepted Answer

Performance is in the average range

Answer

Stanine 5 is the middle band (stanines 4–6 are average), indicating typical performance relative to the norm group.

Question 3

Which of the following BEST describes a norm-referenced interpretation of IDAT results?

Accepted Answer

Comparing a student's score to those of a representative peer group

Answer

Norm-referenced interpretation ranks a test-taker's performance relative to a norming sample rather than a fixed cut score.

Question 4

An IDAT candidate scored at the 60th percentile. Which statement is accurate?

Accepted Answer

The candidate scored higher than 60% of the norming group

Answer

A percentile rank of 60 means the student outperformed 60% of the reference group, not that they got 60% of items correct.

Question 5

Why might an IDAT score report include a confidence interval around the obtained score?

Accepted Answer

To reflect the inherent measurement error in any standardized test

Answer

Confidence intervals acknowledge standard error of measurement, showing the range within which the true score likely falls.
