The TRI52 is a computerized nonverbal intelligence test designed with 52 figurative items which don’t require acquired knowledge.
With excellent Cronbach’s Alpha reliability coefficient value (.92; N = 1,019), the TRI52 raw score has demonstrated high validity.
The TRI52 Reasoning Index (RIX) has shown very high correlations with both the Scholastic Aptitude Test I (SAT I) composite score (.75), and the SAT I Mathematical reasoning test scaled score (.84).
It also very highly correlates with the IQ on traditional intelligence tests such as the Wechsler Adult Intelligence Scale III (WAIS-III) Full Scale IQ (.77) or the Slosson Intelligence Test – Revised (SIT-R3) Total Standard Score.
Thanks to the nonverbal nature of its items, this test is suitable for testing persons without cultural bias. It yields with the RIX, an age-referenced standard score equated on the SAT-I M.
