The GAB is designed to measure an individual’s cognitive ability yielding IQ Equivalents
(low/average through very superior/gifted). The test will differentiate individual abilities: high
school vs. college and occupational levels – factory, office, engineers, and executive personnel. Professionals have used the GAB to heighten achievement, shorten training time, and
reduce drop-out rates by avoiding advancing an individual whose cognitive abilities are below
situational demands.
GAB Test Items:
• Vocabulary: 50 items
• Verbal-Analogy: 35 items
• Arithmetic-Reasoning Problems: 15 items
• Syllogistic-Reasoning Statements: 12 items
Checked by three approaches (test-retest, split-half, and 4 minute and 8 minute), the GAB
yields significant levels in the .80s and .90s. By using 4 and 8 minute time limits, the
adminis-trator can obtain indication of the individual’s performance under speedpressure and power conditions.
