Naglieri Nonverbal Ability Test (NNAT2)

All Loudoun County third grade students will take the Naglieri Nonverbal Ability Test 2 between September 30 and October 11.  The test will be given to students in their regular classrooms during their usual SEARCH time. Please prepare your child by making sure that he/she is healthy, well-rested, and that he/she has eaten a good breakfast on the day of the test.  No other preparation is needed! 

 In order to help you, as parents, better understand the NNAT2, here are some frequently asked questions. 

 1. What does the NNAT2 measure?

The Naglieri Nonverbal Ability Test 2 assesses school learning ability without requiring a student to read, write or speak. Instead, students rely on reasoning and problem solving skills to complete the test items.

Many people assume that intelligence is differentiated in two categories:  verbal and nonverbal. The distinction actually refers to the content of the items on an intelligence test, not to the type of thinking or intelligence required. Verbal and nonverbal tests are two different ways of measuring intellectual ability. 

2. What types of questions are on the NNAT2? 

There are four categories of questions on the NNAT2:

• Pattern completion: requires the student to complete a pattern by determining both general orientation and design details of the missing portion.
• Reasoning by Analogy: requires the students to recognize a logical relationship between several geometric shapes
• Serial Reasoning: requires the student to recognize sequence of shapes and changes in a sequence
• Spatial Visualization: the student must recognize how two or more designs would look when combined

The geometric shapes and designs used for each test item are culture-free.       

3. Who will take the NNAT2? 

Currently, all third grade students in Loudoun County Public Schools take the NNAT2 in the fall of the school year.  The NNAT2 is available to students in grades K-12 for intellectual ability testing. 

 

 

The test has 48 items, which must be completed in 30 minutes.

 

 

Percentile ranks range from 1 to 99, and describe a student's test performance relative to other students of the same age in the national normative reference group. A student performing in the 95th percentile, for example, scored higher than 95% of the students at his/her age.  Ranks between the 25th and 75th percentile fall within the average range of normative expectations. 

 

 

Students may score well on the NNAT2 who do not demonstrate high levels of achievement in the classroom. The NNAT2 demonstrates that these students have the ability to succeed in school, though they may not have acquired the skills required to achieve at that high level. Alternately, there are students who are very strong in the academic domain who may score poorly on the NNAT2. 

The NNAT2 helps us identify students who may not demonstrate their ability on more traditional tests of knowledge because of limited English proficiency, language or learning difficulties, or other factors that may hinder achievement. It should be kept in mind that the NNAT2 scores give only one piece of information about a student.  As with any assessment, some tests will identify the strengths of students more than other tests.
