State the correct order of Intellectual disability in terms of decreasing intellectual functioning (I. Q. range) :
(A) Severe
(B) Mild
(C) Profound
(D) Moderate
Choose the correct answer from the options given below :
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → (B), (D), (A), (C)
The levels of intellectual disability are defined by IQ ranges; the higher the range, the better the intellectual functioning.
(B) Mild — IQs 55 to approximately 70, the highest functioning of the four. Their development is slower than that of peers, but they can function quite independently, hold jobs and have families.
(D) Moderate — IQs 35–40 to approximately 50–55. They lag behind their peers in language and motor skills, can be trained in self-care and simple social skills, and need moderate supervision.
(A) Severe — IQs 20–25 to approximately 35–40. They are incapable of managing life and need constant care.
(C) Profound — IQs below 20–25, the lowest functioning; they too need constant care for their entire lives.
NCERT (2025-26): “Variations of Intelligence … 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). Although the development of people with mild disability is typically slower than that of their peers, they can function quite independently, hold jobs and families. As the level of disability increases, the difficulties are strongly marked. The people with moderate disability lag behind their peers in language and motor skills. They can be trained in self-care skills, and simple social and communication skills. They need to have moderate degree of supervision in everyday tasks. Individuals with profound and severe disability are incapable of managing life and need constant care for their entire lives.…” |
