Not generally. IQ tests are age adjusted, basically to take account of youth and inexperience (under 18) or age and diminishing speed. The reason is that, as we get older, diminishing speed and spatial awareness are balanced by having more knowledge and experience to draw on to solve problems.Now we can compare Full Scale (global) IQs for adults of different ages. A clear decline is evident. The mean WAIS-IV IQ is 100 for ages 20-24 and is 99 for ages 25-44. Then it drops to 97 for ages 45-54, to 94 for ages 55-64, to 90 for 65-69, to 86 for ages 70-74 and to 79 for ages 75+.Abilities change, but IQ scores tend to be very stable. However the intelligence ability is changing during the life, the IQ (intelligence quotient) does not. This measure is defined to have mean of 100 in each age group. So the average IQ e.g. in the age 5 is 100, and the same in the age 50.
