In theory this is what the diploma or GED is already for. These are all certified by the state to show you've completed a certain amount of education to a certain level of quality. What is an SAT or ACT supposed to be on top of all that honestly? Really its tackling a symptom of colleges for whatever reason no longer trusting the states own education departments' diploma or GED. Which is damning considering these schools point to these same states accreditation as a quality measure for their own programs, forgetting that if the diploma is untrustworthy then so are these state accreditation...
Where do the grades on a US high school diploma come from? They are arbitrarily assigned by teachers from the student’s high school, right? One teacher might give everyone good grades, while another will be more strict, and yet another may give good grades to their favourite students only. Grades of two students from the same class are often not comparable, let alone grades of two students from different states.
The SAT and the ACT are standardized tests, meaning that everyone in the country writes the same test on the same day, and the tests are designed to make the test results comparable between different sessions.
There are sometimes state ran standardized tests done to prevent this very issue of certain schools having uneven standards. And both SAT and ACT tests are conducted multiple times a year with completely unequal testing center conditions if you are into considering anything that might introduce a confounding factor (e.g. some schools they have hundreds of kids sit in a gym like what you'd see out of national exams in Korea, other kids might take it in seclusion at a private testing center). Then there is this idea of the extra tutoring people are paying for outside of the school curriculum basically amounting to something akin to paying for the right to use steroids in sports.
There is no way for all 3.7 million high school graduates in the US to write a test in the same conditions. But the SAT and ACT are much better w/r/t similar conditions than grades.

The US is the land of capitalism, so it delegates standardised testing to private for-profit corporations. Many European countries have a nation-wide or state-wide standardised testing system.

I wouldn’t compare tutoring to steroids. In sports, some athletes can afford to spend more time in the gym and to get a better coach, while some can’t, and that might affect their test results.
