The assessment of IQ (Intelligence Quotient) in Brazil is a practice regulated by the Federal Council of Psychology (CFP), and it is essential to use instruments approved by the Psychological Test Assessment System (SATEPSI). These tests undergo rigorous scientific validation criteria, ensuring accuracy and reliability in the results.
If you want to carry out an IQ or intelligence assessment in a professional and recognized manner, it is important to know that only the tests below are approved and recommended for direct measurement of IQ:
Tests That Directly Assess IQ
1. Wechsler Intelligence Scale for Children – 4th Edition (WISC-IV) Widely used to measure children’s IQ, covering different cognitive abilities.
2. Wechsler Adult Intelligence Scale (WAIS III) International standard test for assessing IQ in adults.
3. Wechsler Abbreviated Scale of Intelligence (WASI) Practical and shorter alternative for estimating general IQ, ideal for screening.
4. SON-R (6-40 and 2½-7[a]) Nonverbal test used to measure the IQ of children and adults.
Complementary Tests
In addition to tests that directly assess IQ, there are other approved instruments that provide supplementary intelligence assessments. These tests measure specific abilities, such as logical reasoning, fluid intelligence, or nonverbal intelligence, but do not provide a direct estimate of IQ. Examples include:
° Raven’s Progressive Matrices (Colored and Advanced) – provides only the percentile
° Nonverbal Test of General Intelligence BETA-III
° Logical Reasoning Test (LRT)
° G-36 and G-38
Fundamental Criteria for Choosing an IQ Test
To ensure the quality of the assessment, it is essential to observe the following criteria:
° Approval by SATEPSI: Only tests listed in the CFP system are considered valid.
° Scientific validity: The instruments must have proven accuracy through technical studies.
° Professional application: The application and interpretation of the tests must be carried out exclusively by qualified psychologists.
Why Use Only Regulated Tests?
Using unrecognized tests can compromise diagnostic accuracy, resulting in potentially harmful misinterpretations. Only CFP-approved instruments guarantee reliable results that are accepted in academic, clinical, and professional settings.
