"What does <year>-smart mean though?" is the question you have to answer to make an IQ test. And it's impossible to answer. IQ test-makers have been getting it wrong in various ways since they started. All an IQ test can tell you is how well you do on IQ tests. If IQ correlates to other outcomes, that's because the test was designed (intentionally or not) to correlate with those other outcomes, not because IQ test-makers are meta-geniuses who know the answer to "What does <year>-smart mean though?"

US military uses an IQ test (ASVAB) for personnel assignment. It doesn’t matter what intelligence “actually” is, or how well IQ tests measure it. What is important is that IQ tests are extremely useful in predicting education success, doing effective job assignment, explaining various socioeconomic variables, which is why we use them.
