Question

Quizplus · Accepted Answer

The recommended cutoff for intellectual disability is an IQ below 70, but not everyone with an IQ below 70 will necessarily qualify for a diagnosis of intellectual disability. In fact, only about 2% to 3% of the population falls in this range. The other answer choices are incorrect: A is too absolute, B is too absolute in the other direction, and D is incorrect because IQ cutoffs apply to individuals of all ages, not just adults.
