Norming Dr. Naglieri’s New Tests of General Ability



Dr. Jack A. Naglieri (author of The Naglieri Nonverbal Ability Test, NNAT), Dr. Dina Brulles, and Dr. Kimberley Lansdowne developed three new tests that assess general ability with Verbal, Quantitative and Nonverbal item content. Students can complete all these tests regardless of the language they speak. 

Who is MHS?

MHS is a leading developer of innovative scientifically validated assessments for children and adults. MHS is conducting data collection to provide norms for these new tests of general ability by Naglieri, Brulles and Lansdowne. 

Who can Participate?

In order to obtain norms that represent the US population, all students in classes from Pre-Kindergarten to Grade 12 will be administered the tests. Participants will choose the grade(s) they wish to test. 

What Will Students Be Doing?

Students will be completing the quantitative, verbal and nonverbal tests online using a computer or tablet. Teachers may administer all three tests in one session (with ample breaks given), or administer the three tests on different days, within a two-week period.

How Long Will the Data Collection Take?

On average, students take 25 minutes to complete each test. The maximum time for each test is 50 minutes. In total, it will take approximately 2.5 hours to administer all three tests. 

Where Will the Study Take Place?

Students will be completing the three tests in a group classroom setting during class time. 

When Will the Study Take Place?

Testing will be on school days of the participant’s choosing between February 24, 2020 until the end of the school year. 

Why Participate?

Schools will receive raw scores for all students tested (which can be used to creating a local norm) and compensation for participating (*limits apply).
