"Individuals who are categorised as having intellectual disability show significant variation in their abilities, ranging from those who can be taught to work and function with special attention to those who cannot be trained and require institutional care throughout their lives. You have learnt earlier that the mean IQ score in the population is 100. These figures are used to understand the categories of intellectually disabled. The different levels of intellectual disability are: mild (IQs 55 to approximately 70), moderate (IQs 35–40 to approximately 50 55), severe (IQs 20–25 to approximately 35–40), and profound (IQs below 20–25)."
