is 129 a good IQ score for an 18 year old?

Question

i just done an IQ test for school and this is what i got. when i was 16 i got 136 on my school's IQ test. is it normal for results to flucuate like that or am i just getting dumber?

Answer 1

Given that the standard average is between 90 to 105, your score ranks you in the 'above average', of course this all depends on where you have taken your IQ test. Internet tests are not as accurate and can be easily tricked to either give very high or very low scores.

My suggestion is for you to try as many tests as possible and come up with an average, this will be a more accurate of where your IQ stands.

Answer 2

It's a great score for your age. IQ test results will vary each time you take them due to the questions asked.
P.S. If your IQ is so good, how come you didn't use the spell check before you posted your question?

Understanding IQ Scores


IQ stands for intelligence quotient. Supposedly, it is a score that tells one how “bright” a person is compared to other people. The average IQ is by definition 100; scores above 100 indicate a higher than average IQ and scores below 100 indicate a lower that average IQ. Theoretically, scores can range any amount below or above 100, but in practice they do not meaningfully go much below 50 or above 150.

Half of the population have IQ’s of between 90 and 110, while 25% have higher IQ’s and 25% have lower IQ’s:

Apparently, the IQ gives a good indication of the occupational group that a person will end up in, though not of course the specific occupation. In their book, Know Your Child’s IQ, Glen Wilson and Diana Grylls outline occupations typical of various IQ levels:

140
Top Civil Servants; Professors and Research Scientists.

130
Physicians and Surgeons; Lawyers; Engineers (Civil and Mechanical)

120
School Teachers; Pharmacists; Accountants; Nurses; Stenographers; Managers.

110
Foremen; Clerks; Telephone Operators; Salesmen; Policemen; Electricians.

100+
Machine Operators; Shopkeepers; Butchers; Welders; Sheet Metal Workers.

100-
Warehousemen; Carpenters; Cooks and Bakers; Small Farmers; Truck and Van Drivers.

90
Laborers; Gardeners; Upholsterers; Farmhands; Miners; Factory Packers and Sorters

Answer 3

It might fluctuate a bit depending on how you were on testing day, but 129 and 136 are pretty close. IQ is not supposed to change much, unless you've burnt off some brain cells.

100 is average. This means that half of America is below average and half of America is above average. 129 or 136 is quite good.

Answer 4

Note sure if I could give you the right answer to that but would like to add to- if IQ's change with age what would an adult IQ of 129 mean to an adult in there middle 50's.

Answer 5

411 Fantasy Football - IQ tests have ALWAYS been given in odd or even numbers. I have no clue where you heard this even only thing.

It's above average. The IQ does go down as you get older. It's normal. Mine went up, which I was told is strange.

Answer 6

As far as I know, the IQ scores are indexed at 100 being normal. That means that theoretically there is no such thing as a "perfect score", because you could always have someone MORE intelligent than anyone who has been tested so far.

Answer 7

Don't want to be offensive.....but a twelve year old has an IQ of 155....but an 18 year old have an iq of 129????.....there's something wrong....definitely...

Answer 8

"I just done an IQ test"? "Flucuate"? I'd say you're getting dumber.

I was unaware IQ tests scored in odd numbers.
