GAT Scoring System 3

Question 1

Which statistical measure is most commonly used to set the 'average' performance benchmark when norming a GAT score?

Accepted Answer

Mean

Answer

The mean (arithmetic average) is the most commonly used measure to establish the benchmark for norm-referenced scoring.

Question 2

A test-taker receives a GAT score report showing a 'confidence interval' around their score. What is the purpose of this interval?

Accepted Answer

To indicate measurement error and the likely range of their true score

Answer

A confidence interval reflects the standard error of measurement, showing the range within which the test taker's true score likely falls.

Question 3

If a GAT section has 40 questions and a student answers 30 correctly, what is their raw score for that section?

Accepted Answer

30

Answer

The raw score equals the number of correct answers, which is 30 in this case.

Question 4

What does it mean when GAT scores are described as 'norm-referenced'?

Accepted Answer

Scores are interpreted relative to the performance of a reference group

Answer

Norm-referenced scoring compares an individual's performance to that of a defined group, not to a fixed standard.

Question 5

In which situation would a student's GAT scaled score increase even if their raw score stayed the same?

Accepted Answer

If they retook the test on a harder test form

Answer

If a harder test form is equated upward, the same raw score may convert to a higher scaled score to maintain fairness.
