When Will I Receive My Child's Scores?

Following the test, you will receive an NNAT score report in the mail. Test administration dates vary by school and location, but generally scores will be sent out around two months after the test. The score report is detailed and will give you a general idea of whether or not your child qualifies for a gifted program.

How Are Scores Calculated?

The score report you will receive will include three basic scores:

  • Raw Score: This score is simply the number of items answered correctly. For example, if a child correctly answered 20/48 questions, his or her raw score is 20/48.
  • Naglieri Ability Index (NAI): The raw score is then converted using the Naglieri Ability Index (NAI) score, which compares your child to other children in the same age group who took the NNAT. The maximum NAI score is 160 and the average score is 100. NAI scores are normalized so that 68% of students in the general population receive a score between 84 and 116.
  • Percentile Rank: This score is used to compare the student’s performance to that of a national sample of students of the same age. For example, if a five-year-old student has a percentile rank of 70%, this means the student scored as well or higher than 70% of five-year-old students who were tested nationally. Percentile Rank ranges from 1-99.

Eligibility for Gifted Programs

Every school district has different criteria pertaining to what NNAT scores are needed in order to qualify for entry into gifted and talented programs. For example, in some districts, students who score at or above the 92nd percentile on the NNAT qualify for gifted and talented programs. Students scoring between the 85th and 92nd percentiles qualify for a portfolio review, in which additional information about the student is examined. Other schools only accept students with NNAT scores at or above the 95th percentile.

In the Houston Independent School District, NNAT scores are converted using a point system, in which the NNAT score makes up roughly half of the application for admissions into the gifted Vanguard program. Learn more about gifted testing in your local school district.

In New York City, students take the NYC Gifted and Talented Test, which is comprised of sections from both the NNAT and the OLSAT. Both the OLSAT and NNAT sections are weighted equally on this test.Students scoring at or above the 97th percentile are eligible for placement in both citywide and district gifted and talented programs. Students who perform at or above the 90th percentile are only eligible for placement in gifted and talented district programs. Ask your local school district what NNAT score your child needs in order to qualify for a gifted and talented program. Learn more about the NYC G&T Test.

"The practice questions helped my daughter prepare for a TAG program test. She found it helpful to prepare her for the exam and provide her with an idea of what would be on the exam and she scored in the 99th percentile! On top of that, the site was easy to use!"
