Since 2016 the SAT has been better aligned with high school curricula.
The SAT test is wholly owned and developed by the College Board. The SAT test is intended to assess student's readiness for college. The SAT was originally designed not to be aligned with high school curricula.  Several adjustments were made for the version of the SAT introduced in 2016 to reflect more closely on what students learn in high school.
