This section provides information about the Naglieri Non-Verbal Ability Test® (NNAT®) and suggestions for material which can be used to prepare your child to provide the best performance possible.
The Naglieri Non-Verbal Ability Test® (NNAT®, ) is one of the tests used as a screen for gifted program entry. It is a short (about 30 minutes), multiple choice test, with no reading. As the test name suggests only non-verbal (also called spatial or figural) reasoning ability is tested.
There are seven different levels of the NNAT® for administration from Kindergarten to Gr 12. Preschool children can be tested using the Kindergarten level test. Tests include up to four different types of questions - pattern completion, reasoning by analogy, serial reasoning and spatial visualization.
Pattern completion problems, as the name suggests, require children to identify the option which will complete the pattern.
Reasoning by Analogy requires the identification of relationships between shapes. The relationship between a large square and a small square, for example, is analogous to the relationship between a large circle and a .... small circle. Relationships may be presented in more than two dimensions.
Serial reasoning problems require children to identify the shape which comes next in a pattern.
Spatial visualization problems involve visualizing how objects might look when rotated or otherwise transformed or combined.
The NNAT® is referred to as a matrix reasoning test because of the format in which the questions are presented. Similar types of analysis can be taught, and tested, using different formats. The figural analysis sections of Building Thinking Skills has chapters teaching the skills tested for in the NNAT®. The LUK Learning System has a number of matrix reasoning problems and its design is well suited to both teach required skills and raise awareness of what to look for in problems. These two products are our top recommendations for test preparation. We have also identified products which work on associated skills like visual perception, logic and reasoning through analogy which may aid a child in performing at the optimum level. You can view our suggestions by choosing your child's grade level above.
