Anders Jensen’s IQ test (‘iqtest.dk’)

This non-verbal IQ test is based on the well known Raven’s Progressive Matrices and measures your fluid intelligence. The IQ test is culture fair - eliminating the effect of cultural factors such as vocabulary, mathematics and general knowledge. The calculation of IQ is based on answers from more than 250,000 people. The test is based on seeing relationships in abstract geometrical shapes. It is an excellent measure of fluid intelligence, and thus ideal for assessing the impact of training with High IQ Pro®.

The TRI-52 (Test of Inductive Reasoning)

This non-verbal IQ test assesses your fluid intelligence (and general IQ) through culture fair nonverbal questions. The TRI52 raw score has demonstrated high validity.

The TRI-52 correlates very highly 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.

The TRI52 Reasoning Index (RIX) has shown very high correlations with both the Scholastic Aptitude Test I (SAT I) combined score (.75), and the SAT I Mathematical reasoning test scaled score (.84). In the US you can use this test to predict your SAT performance.
