While the NNAT-I is no longer available from Pearson, we do offer some alternatives for measuring non-verbal ability, for example: the Raven's 2 and the Wechsler Nonverbal Scale of Ability. If you would like to continue purchasing the NNAT-I, please visit the MHS website.

Ideal for use with children who do not speak English as their first language, NNAT® - Individual Administration is language free and culture fair. No reading, writing, or speaking is required of students; they merely point to the answers they feel are correct. The test uses progressive matrices, which are unbiased for minority students, hearing-impaired students, and children with impaired colour vision. Approved for assessing non-verbal ability for Special Examination Arrangement. 

NNAT® - Individual Administration allows for a fair evaluation of students' nonverbal reasoning and general problem-solving ability.

NNAT® - Individual Administration includes four item types:

  • Pattern Completion
  • Serial Reasoning
  • Reasoning by Analogy
  • Spatial Visualisation.
