The UNIT2 provides a fair assessment of intelligence for children and adolescents who have speech, language, or hearing impairments; who have different cultural or language backgrounds; or who are verbally uncommunicative.


  • Includes brand-new normative samples and upward extension of normative tables through age 21.11. The UNIT2 also contains new reliability and validity studies in which particularly rigorous techniques involving sensitivity, specificity, and ROC/AUC were used to ensure diagnostic accuracy.
  • Abbreviated Battery, Standard Battery With Memory, Standard Battery Without Memory, and Full Scale Battery are available.
  • Provides an entirely nonverbal stimulus-and-response administration format and incorporates full-color stimuli, manipulatives, and pointing response modes to engage examinees.
  • Offers a wide breadth of use with exceptional students and provides a fair assessment of culturally and linguistically different examinees.
  • Normative data were collected from a comprehensive sample of 1,802 individuals in 33 states representative of U.S. Census statistics.
