SAT/ACT are basically poor IQ tests, because study for them results in heavily loading onto memory aspect of IQ but unloading on some others somewhat. Ideally, you would want an IQ test and the 'Big Five' personality traits. The latter though can be annoying to get. I have seen some firms get very good results by basically using a disguised IQ test, there are some firms that basically compose the tests, give them to 1000s of people and perform the factor analysis to extract IQ from the test, then contract the the test out for hiring departments. Some of those tests are pretty creative in that most people wouldn't know they were taking an IQ test.

Before people state strong assumptions one way or the other, have there ever been any studies that measured the relationship between test scores and IQ? If so, what did they say?

  Yes. If you look you will find published literature on the subject. The plots plotting SAT/ACT and IQ will have an obvious trend but be very noisy. Hence why they are poor IQ tests, you can have a decent guess at someone's IQ based on their test results but it's not ideal.

  The whole point of IQ tests at the very beginning was to predict how well you can do academically. Technically every test is an IQ test.

  It’s an IQ test. Not a culture fair one, like Raven’s Progressive Matrices, but it’s as much an IQ test as coarse, quick and dirty one like Wonderlic is. > Scholastic assessment or g?

This research established the relationship between SAT and g, as well as the appropriateness of the SAT as a measure of g, and examined the SAT as a premorbid measure of intelligence. In Study 1, we used the National Longitudinal Survey of Youth 1979. Measures of g were extracted from the Armed Services Vocational Aptitude Battery and correlated with SAT scores of 917 participants.

We provide equations for converting SAT scores to estimated IQs; such conversion could be useful for estimating premorbid IQ or conducting individual difference research with college students. https://journals.sagepub.com/doi/abs/10.1111/j.0956-7976.2004.00687.x https://journals.sagepub.com/doi/abs/10.1111/j.0956-7976.200...
