NNAT3 Scoring and Interpretation of Results 4

Question 1

A district uses NNAT3 scores to identify students for gifted services. Which score type provides the most defensible single-number criterion?

Accepted Answer

Naglieri Ability Index

Answer

The NAI is a normalized standard score on a common scale, making it the most legally and psychometrically defensible criterion for placement decisions.

Question 2

How does the NNAT3 handle the scoring of omitted items (items the student did not attempt)?

Accepted Answer

Omitted items are scored as incorrect and lower the raw score

Answer

Like most standardized ability tests, unattempted items on the NNAT3 receive no credit, reducing the student's raw score.

Question 3

Which of the following correctly describes the relationship between raw score and NAI on the NNAT3?

Accepted Answer

The same raw score yields higher NAI for a younger student compared to an older student at the same age level

Answer

Because norms are age-based, a younger student who achieves the same raw score as an older peer may receive a relatively higher NAI, reflecting superior performance for their age.

Question 4

A teacher receives an NNAT3 report stating a student's score is in stanine 4. What is the appropriate interpretation?

Accepted Answer

The student's performance is slightly below average but within the broad average range

Answer

Stanine 4 falls just below the middle band (stanine 5) and is considered low-average, not failing or qualifying for gifted placement.

Question 5

What does the Standard Error of Measurement (SEM) indicate in the context of NNAT3 score reports?

Accepted Answer

The typical amount by which an obtained score may differ from a student's true score

Answer

The SEM quantifies score reliability by estimating how much the obtained score might vary from the hypothetical true score due to random measurement error.
