NNAT Score Reports for Parents

Understanding your child's NNAT results

After schools give the Naglieri Nonverbal Ability Test (NNAT), student score reports communicate test outcomes to parents and guardians. These results are generally delivered to families by mid-December for fall testing and by early April for winter testing. A child's NNAT results may be an additional element to inform parent and guardian decisions on whether to refer their children for Advanced Academic Program (AAP) Level IV services.

Fairfax County Public Schools provides a cover letter to accompany the score report. The cover letter explains what the results include and how they can be used.

SCORE REPORT COVER LETTER

Naglieri Nonverbal Ability Test Third Edition

Dear Parents and Guardians:

Your child recently took the Naglieri Nonverbal Ability Test Third Edition (NNAT3). The NNAT3 is a brief nonverbal measure of general cognitive ability and does not require the student to read, write, or speak.

Like any standardized test, the NNAT3 measures only some of your child’s skills, and the results represent his or her performance on the day the test was given. Therefore, these scores are only one estimate of his or her true ability. Test scores should never be used alone to make decisions about services or supports, but they can be helpful when interpreted in conjunction with other information. In Fairfax County Public Schools, NNAT3 results are used as one of several measures to determine Advanced Academic Program (AAP) services.

NNAT3 results for your child are reported on the attached Student Report. Here are some specialized terms you will find on the Student Report.

The Naglieri Ability Index (NAI) shows your child’s performance compared to a nationally representative sample of students approximately the same age. The NAI range is from 50 to 160, with 100 being the midpoint.
Raw Scores show the number of test items your child answered correctly out of the total number of items on the test.
Scaled Scores show your child’s raw score converted to a consistent scale.
Stanines show your child’s performance on a standardized scale from 1 (lowest) to 9 (highest), with the 5th stanine being the midpoint.
Percentile Ranks (PR) indicate the percentage of students approximately same age whose scores fall below the score your child received. PRs range from a low of 1 to a high of 99. For example, a PR of 45 would mean your child performed as well as, or better than, 45 percent of the students who took the test nationally.
The Normal Curve Equivalent (NCE) converts your child’s score to a scale from 0 to 100 similar to a PR, but with equal intervals between each score.

If you have questions about this score report, please contact the Advanced Academics Resource Teacher (AART), ____________________________, or School Test Coordinator, ____________________________, at your child's school.
