Sigma Test Light

Sigma Test Light   is a psychometric intellectual assessment instrument with many important differences compared to other cognitive tests. It follows the same line as the Sigma Test, Sigma Test VI and Sigma Test Extended, which are internationally recognized as some of the best intelligence tests out there, and are accepted for admission into the main high IQ societies on 5 continents.

The Sigma Test Extended was designed to be the most difficult intelligence test that exists and with better construct validity at the highest levels, making it possible to correctly evaluate people with IQs above 220, through questions with an adequate level of difficulty and that require skills compatible cognitive skills. It is completely different from tests like Stanford—Binet (SB), which allegedly measure up to 225, when in fact the most difficult questions on the SB are at a level of 130, that is, anyone with an IQ of 130 would have about a 50% chance of getting the most difficult SB questions right, in addition to the cognitive processes involved in solving them being too primary to evaluate at levels above 125.

The Sigma Test Light is a more accessible version of the Sigma Test, aimed at audiences with IQs between 90 and 180, and can extend slightly beyond this range, covering the range of 75 to 190.

The optimal range of precision and accuracy is in the range of 100 to 170, aimed at people classified as having above average intelligence, who obtained scores from 110 on conventional IQ tests and want a more representative assessment of their real ability. intellectual.

Although the meaning of “above average” is arbitrary and vague, it is a widely accepted standard. In academic books on Psychometrics you can find classifications by IQ range according to the opinions of different authors, including the most traditional ones such as Terman, Wechsler, Levine and Woodcock, as well as others that are less known. These classifications are subjective and have no scientific value, in which the cut-off levels are “guessed” by the authors. In the case of Lewis Terman, for example, he decided to “guess” that the classifications should be like this:


Pinter decided they should be like this:


Levine decided they should be like this:
