NGAT scores explained without fake cutoffs.

What an NGAT score report can show

The NGAT is not one single task. The publisher describes three separate ability measures: Verbal, Nonverbal, and Quantitative. A district may administer one, two, or all three depending on its process.

The official NGAT FAQ says reports provide three scores corresponding to those three tests, with standard scores, percentiles, and stanines used for interpretation. The same FAQ says these are not individual subscores in the usual test-report sense; they are scores for the separate NGAT tests.

If a student completes enough NGAT tests, a total score may appear. FCPS's sample score report notes that if only one test was administered, a total score cannot be calculated.

Start with the standard score.

MHS's scoring guidance says NGAT standard scores are standardized with a mean of 100 and a standard deviation of 15. In plain language, 100 is the average point on the scale.

The standard score is often the cleanest number to compare across the NGAT Verbal, Nonverbal, and Quantitative tests. MHS specifically cautions that percentile ranks are useful for comparison, but they should not be used like ordinary arithmetic values.

A percentile is a rank, not percent correct.

The official NGAT score-interpretation page makes the key point directly: percentile rank is not the percent of questions answered correctly. It is a way to compare a student's performance with a comparison group.

That comparison group matters. MHS describes both national and local norms. FCPS's sample score report says it uses a national comparison sample in grades 1-6 and a local comparison sample in grades 7 and above.

Stanines are simpler bands from 1 to 9. They can be useful for a quick overview, but the standard score and district rules usually matter more for careful interpretation.

Districts decide what the score does.

FCPS is the clearest public example in the current source set. FCPS says it uses the NGAT to meet Virginia's nationally normed ability-assessment requirement, with administration in grade 2 and select students in grades 3-7.

FCPS also says NGAT results are one of several measures used in the Advanced Academic Program screening process. That is the right mental model for most districts: ability-test data may matter, but it is usually read alongside other local evidence.

Other districts may use different grade levels, testing windows, comparison groups, retest policies, and review factors. That is why the honest answer to "is this score good enough?" is: check your district's current rules.

What score ranges mean, carefully.

A score near 100 is near the average point of the NGAT standard-score scale. Scores above 100 are above that average point, and scores below 100 are below it. The further a score is from 100, the more unusual it is within the comparison group.

But a score range is not a universal gifted label. A district may use local norms, national norms, multiple measures, committee review, parent referral, teacher input, achievement data, or other evidence. A number that triggers review in one district may not mean the same thing in another.

What to do when the report arrives

1. Confirm the comparison group. Is the report using national or local norms?
2. Look at the separate test scores. Verbal, Nonverbal, and Quantitative may tell different stories.
3. Find your district's screening page. Look for current-year grade levels, referral rules, retest deadlines, and whether scores start a review rather than finish it.
4. Ask calm questions. If the score seems inconsistent with classroom performance, ask the school what additional evidence can be considered.

FCPS's current AAP page describes a one-time retest process for the FCPS-administered nationally normed ability test. That is a local policy example, not a national rule. If you are in another district, use the district's own page.
