Safety Warning CHOKING HAZARD - Small parts. Not for children under 3 years.
BY BRUCE A. BRACKEN AND R. STEVE MCCALLUM
With an entirely nonverbal administration and response format, the UNIT2 assesses intelligence, regardless of the student’s language skills, hearing, cultural background, or English proficiency. Its six subtests include Symbolic Memory, Nonsymbolic Quantity, Analogic Reasoning, Spatial Memory, Numberical Series, and Cube Design.
The examiner employs eight relatively universal hand and body gestures to explain tasks to the examinee. The student responds by pointing, making pencil marks, or using manipulatives. The test offers three administration options—Abbreviated, Standard, and Extended Batteries—for screening, diagnostic, and eligibility decisions, respectively. All can be hand- or computer-scored.
UNIT scores predict academic achievement and differentiate among students with intellectual disability, learning disabilities, speech/language impairments, or giftedness.
