This year, Northshore School District used the Naglieri Nonverbal Ability Test (NNAT3) as one of its screening tools. Screeners are used to identify students with the potential for Highly Capable Program eligibility. Screening results will be communicated to schools and families in January.
What is the NNAT3? The NNAT3 is a nonverbal, culturally neutral measure of general ability. It is helpful in identifying students who exhibit the potential for advanced academic achievement. This is one measure in a portfolio of assessment data that provides a window into a student’s thinking and reasoning ability.
What level of the NNAT3 will be administered to my student? Level administered is determined by the student’s birth date. Therefore, students within any grade level classroom may receive different levels of the NNAT3. The date of birth is entered during a student’s account creation, and the NNAT3 platform generates the level presented to the student.
How is the NNAT3 administered? The NNAT3 is administered online via a computer or tablet device. Students take the test during the school day.
How long does it take to administer the NNAT3? NNAT3 takes approximately 30 minutes to administer. Extended time is available for students with documented extended time accommodation. Proctors follow directions for administration in order to ensure district-wide consistency of administration.
When is the NNAT3 typically administered? The NNAT3 is one tool used by Northshore’s Highly Capable Eligibility Process. The department typically administers the NNAT3 each winter. The Board determines which grade levels will participate in the NNAT3 as part of its yearly approval of the Highly Capable Eligibility Process.
How is performance on the NNAT3 measured? The score obtained from the NNAT3 is called the Naglieri Ability Index (NAI). A NAI of 100 is considered average, and 95% of students will score between 84 and 116. The Highly Capable Department uses a student’s National Percentile Rank (NPR) to determine eligibility for further testing. The NPR indicates how the student performed relative to other test-takers. A student with an NPR of 85 performed as well as, or better than, 85% of their same-age peers. An NPR between 25 and 75 is considered to be within the average range.
What is the connection between my student’s NNAT3 percentile and classroom performance? The NNAT3 is a measure of a student’s cognitive ability without access to content and instruction. A student need not read, write, or speak English in order to take part in the test. The NNAT3 is not a measure of classroom performance and is not correlated to the standards and content of focus in a student’s current grade level. It is possible that a student will achieve a high NNAT3 percentile score, yet score differently on tools that measure academic achievement. A student who scores well on the NNAT3 is likely to have potential to develop strong skill sets in visual arts, math, and science.
How is the NNAT3 used in the HiCap eligibility process? NNAT3 performance is one data point within a larger portfolio of data. The NNAT3 alone will not qualify nor disqualify a student from potential eligibility for Highly Capable services.
