NNAT 2 and 3 (Nationwide)
The Naglieri Nonverbal Ability Test (NNAT) is a standardized nonverbal test designed to assess the reasoning ability of students ages 5 to 17. The NNAT is utilized as a part of the admission process for gifted and talented programs throughout the country. NNAT is one of two tests that are administered for the NYC Gifted and Talented TesT in NYC.
The NNAT is a nonverbal test which measures abstract spatial thinking skills. Since the NNAT requires very little spoken language (even in its directions), it is considered a better indicator of raw intelligence as it does not discriminate against children whose first language is not English.
The timing of the test varies depending on school districts across the country. Check with your school to see when the test will be administered.
There are seven different levels of the NNAT which are administered to students depending on their current grade in school. Students at the preschool level can be tested using the test designed for kindergarten students.
The NNAT has four question types:
1. Pattern Completion
In Pattern Completion items students are given a design and asked to identify which portion is missing.
2. Reasoning by Analogy
In Reasoning by Analogy questions students must recognize relationships between several geometric shapes.
3. Serial Reasoning
Serial Reasoning questions require students to recognize the sequence of shapes.
4. Spatial Visualization
In Spatial Visualization questions students must combine two or more objects and find what the resulting figure will look like.
The latest version, the NNAT3, takes 30 minutes to complete and includes 48 questions broken down into these four unique question types.
The score your child receives will be an overall percentile rank. This score is calculated in two ways (see figure below):
Raw Scores: The raw score is the number of correctly answered questions out of the total number of questions. The NNAT has 48 questions, and its raw score is out of 48.
Individual Percentile Rank: A standardization process occurs in which individual raw scores are converted to percentile ranks by comparing them to the raw scores of other children in the same age group (3 month age bands).
