How do SAT and ACT scores compare to the Matura, IB, or French Bac in Luxembourg?

Families in Luxembourg often wonder how U.S. standardized tests align with the local systems like the Matura, IB, or French Bac. The SAT tends to align more closely with algebra and reading comprehension skills emphasized in these programs, while the ACT includes a broader mix of math concepts such as geometry and trigonometry, plus a faster pace across sections. Unlike the Matura or Bac, which focus on extended coursework and oral exams, the SAT and ACT are timed multiple-choice tests designed to measure college readiness. Because of these differences, targeted preparation is crucial to bridge the gap between local curricula and U.S. admissions expectations.
