Naglieri (NNAT) Highlights

The Naglieri Non-Verbal Ability Test (NNAT) is one of the tests used as a screen for gifted program placement.  
 
There are seven different levels of the NNAT for administration from Kindergarten to Gr 12.  Four different types of questions are included in the tests.  The number of each type at the different grade levels is shown below. 
 

Level	Grade	Pattern Completion	Reasoning by Analogy	Serial Reasoning	Spatial Visualization	Total
A	K	30	8			38
B	1	19	13	6		38
C	2	10	12	11	5	38
D	3-4	6	10	8	14	38
E	5-6	5	6	8	19	38
F	7-9	2	10	8	18	38
G	10-12		7	7	24	38

The NNAT is referred to as a matrix-reasoning test because of the format in which the questions are presented.  Similar types of problems can be taught, and tested using different formats. Working on associated skills like visual perception and spatial concepts may aid a child in performing at the optimum level.

 

Pattern Completion

Pattern completion items require a student to look at a design in a large rectangle with a portion missing and determine which of the choices correctly completes the pattern.

 

 

Reasoning by Analogy

Here the student has to recognize a logical relationship between several geometric shapes. Reasoning by Analogy becomes more difficult as the logic increases in complexity and number of dimensions involved.

 

 

Serial Reasoning

The items in Serial Reasoning matrices are constructed using a series of shapes that change across the row horizontally and the columns vertically through the design.  These items demand that the child recognizes the sequence of shapes to figure out the option from the bottom row.

 

Spatial Visualization

Spatial visualization items are among the more difficult questions, especially when involving shapes that intersect in ways that are difficult to recognize or involve rotation.  These questions require the student to recognize how two or more designs would look if combined, requiring visual perception.
