Jobs and Intelligence:

One notable finding is that the correlation between IQ and job status is just about as high if the IQ test is given in childhood, decades before people enter the job market, as it is among young adults who are taking an intelligence test after years of education. For example, in a small but elegant longitudinal study of childhood intelligence and adult outcomes, the boys and girls in the sample were given IQ  tests in childhood and then their job statuses and levels of schooling were measured on standard scales after they were at least 26 years old. The IQ scores they got when they were 7 or 8 years old were about as correlated with the status level of their adult jobs as their adult IQ would have been. Inasmuch as childhood IQ is more correlated with status than completed education, as in some studies, the thesis that IQ scores really just measure educational level is weakened.
