Borderline intellectual functioning, previously called borderline mental retardation (in the ICD-8), is a categorization of intelligence wherein a person has below average cognitive ability (generally an IQ of 70–85), but the deficit is not as severe as intellectual disability (below 70).
Intellectual disability, formerly called mental retardation (MR) is defined as having an IQ score below 70 whereas an IQ score in the range of 71–84 is termed as “borderline intellectual functioning”.
Diagnosing Intellectual Disability
A full-scale IQ score of around 70 to 75 indicates a significant limitation in intellectual functioning. 2. However, the IQ score must be interpreted in the context of the person's difficulties in general mental abilities.
70 to 84: Borderline mental disability. 85 to 114: Average intelligence. 115 to 129: Above average or bright. 130 to 144: Moderately gifted.
FAQs (Frequently Asked Questions) When did Elon Musk take an IQ test? The Tesla CEO is estimated to have an IQ score of around 155.
What's the lowest IQ ever? The lowest IQ ever would be 0. However, no one has ever scored that. Scores below 75 usually indicate a cognitive disability.
Approximate IQ range of 50 to 69 (in adults, mental age from 9 to under 12 years). Likely to result in some learning difficulties in school. Many adults will be able to work and maintain good social relationships and contribute to society.
In many cases, an IQ test score that falls below 70 is considered low IQ, while a score of above 140 indicates high IQ. In the past, scores below 70 were used as a marker to identify intellectual disabilities.
Scores of 80 to 89 are considered low average. Scores of 70 to 79 are considered borderline impaired. Scores of 55 to 69 are considered a mild impairment. Scores of 40 to 54 are considered a moderate impairment.
Does an individual's IQ change with age? An individual's IQ does not change with age. In other words: if you did an IQ test now and then another one in 10 years' time, your IQ score will probably be very similar. This is because IQ is always measured relative to other people your age.
Based on the 68-95-99.7 Rule, approximately 68% of the individuals in the population have an IQ between 85 and 115. Values in this particular interval are the most frequent. Approximately 95% of the population has IQ scores between 70 and 130.
Critical interpretation of full-scale IQ scores. To further simplify it: An IQ of 75 means that an 8-year-old child will function intellectually overall at 75% of the average 8-year-old's intellectual functioning ie, at an average of a 6-year-old level.
In general, an IQ score is defined with a median and mean of 100. Scores above 130 are labeled as above average or “very superior,” while scores under 70 would be considered below average or labeled as “borderline impaired.” Most people have an average IQ between 85 and 115.
Although IQ can change for an individual, across a population it is well established that IQ is stable across the lifespan. This does NOT mean that our abilities do not change as we age. IQ (as the name indicates) is a QUOTIENT, i.e., your score is calculated relative to persons of your age.
But genetics can explain the wide range of possible IQs too because so many different genes are involved in developing and running a brain. It is possible, for example, to inherit all the higher IQ genes from each parent and leave the lower IQ ones behind. Now the child will be brighter than the parent.
Like most aspects of human behavior and cognition, intelligence is a complex trait that is influenced by both genetic and environmental factors.
