IQ Assessment

Historically, IQ was a score obtained by dividing a person’s mental age score, obtained by administering an Intelligence test, by the person’s chronological age, both expressed in terms of years and months. The resulting fraction (quotient) was multiplied by 100 to obtain the IQ score. For modern IQ tests, the raw score is transformed to a normal distribution with mean 100 and standard deviation. This results in approximately two-thirds of the population scoring between IQ 85 and IQ 115 and about 2 percent each above 130 and below 70.

Understanding Intelligence: Factors, Heritability, and the Role of IQ Testing

Scores from Intelligence Tests are estimates of Intelligence. Unlike, for example, distance and mass, concrete measures of Intelligence cannot be achieved given the abstract nature of the concept of “Intelligence”. IQ Scores have been shown to be associated with such factors as nutrition, parental socioeconomic status, morbidity and mortality, parental social status and perinatal environment. While the heritability of IQ has been investigated for nearly a century, there is still debate about the significance of heritability estimates and the mechanisms of inheritance.

Applications and Trends in IQ Testing: From Educational Placement to the Flynn Effect

IQ Scores are used for educational placement, assessment of Intellectual disability and evaluating job applicants. In research contexts, they have been studied as predictors of job performance and income. They are also used to study distributions of psychometric intelligence in populations and the correlations between it and other variables. Raw scores on IQ tests for many populations have been rising at an average rate that scales to three IQ points per decade since the early 20th century, a phenomenon called the Flynn effect.

Investigation of different patterns of increases in subtest scores can also inform current research on human intelligence.

BKT - Binet Kamat Test of Intelligence

The test consists of six dimensions – language, memory, reasoning, conceptual thinking, visual motor and social intelligence (verbal and non- verbal).


The Malin’s intelligence scale for children (MISIC) is the Indian adaptation of the Wechsler intelligence scale for children (WISC). The scale comprises twelve subtests divided into verbal and performance groups.

An IQ Assessment is a standardized test designed to measure a person’s intelligence or cognitive abilities.

 IQ is measured through various standardized tests that assess different aspects of intelligence, such as problem-solving, logical reasoning, and verbal and non-verbal abilities.

An IQ score represents a person’s performance on an IQ test relative to the average performance of the population. It provides an estimate of cognitive abilities and is typically interpreted within a standardized scale.

IQ tests are generally considered reliable, as they have established procedures for administration and scoring. They undergo rigorous testing to ensure consistency and validity.

While IQ is relatively stable over time, it can be influenced by various factors such as education, environment, and life experiences. Some changes in IQ scores may occur due to developmental factors or specific interventions.
