CHILD DEVELOPMENT PEDAGOGY

Detailed explanation-1: -For example, on The Wechsler Adult Intelligence Scale and the Stanford-Binet test, scores that fall between 90 and 109 are considered average IQ scores. On these same tests, scores that fall between 110 and 119 are considered high average IQ scores. Scores between 80 and 89 are classified as low average.

Detailed explanation-2: -110-119 is “superior intelligence", while 90-109 is “normal or average intelligence". An IQ between 80 and 89 suggests “dullness", while a score of 70 to 79 is classed as “borderline deficiency".

Detailed explanation-3: -Now, the IQ 90 score is considered ‘normal’ or average, yet it is at its lowest point. According to Lewis Terman’s scale, the typical range is between IQ 90 and 109. The preceding range is from 80 to 89 and represents ‘dullness. ‘ This signifies that IQ 90 is below average.
