Our program offers Cognitive Abilities Test (CogAT) and Naglieri Nonverbal Ability Test (NNAT-3) at certain points of the year.

In alignment with schedules of local schools, we will be offering the NNAT-3 one day this March for first graders

Registration is now open for the following dates.

Saturday March 16, 2024 10am: Registration

NNAT may not be taken more than once in a six-month period.

Results will be available within 4 weeks. If you have a deadline sooner than 4 weeks, we will do our best to get results to you by then.

Fees are as follows:

  • Fee is $125 per student

Fee Waiver is available if you meet both of these criteria and provide documentation:

  1. Your child qualifies for Free/Reduced Lunch at school, or Medicaid
  2. You are applying for AAP

Alternatively, we offer the WISC-V year-round. See the Individual Assessments tab for more information.

We will offer CogAT or NNAT testing for select students this summer, who meet both of these criteria:

  1. Your child is new to the region
  2. Your child is applying to AAP (or similar program) for Fall 2024 admission.

We will offer CogAT/NNAT on 4 to 5 testing dates between September 2024 through January 2025. Look back here for registration details in August 2024.

All other students may test with us individually with the WISC-V year-round. See the Individual Assessments page for more details, and call 703-993-4200 to register.
