The SAT went digital and adaptive in 2024, the ACT was overhauled in 2025, and a growing list of top colleges reversed their test-optional policies within the same window. None of that happened by coincidence, and this post explains why.
Why standardized tests changed at the same moment AI became widespread.
Much of what a student turns in from home can now be produced or heavily assisted by AI, which means an essay, a project, or a take-home assignment no longer tells a school or a college as much about a student as it once did. Standardized tests have changed in direct response to this shift.
The College Board rebuilt the SAT in 2024. It is now digital and adaptive, roughly two hours instead of three, and built around reasoning rather than memorization: reading closely, drawing inferences, and working through a problem in context rather than recalling a fact. The ACT went through its own overhaul in 2025.
The College Board has described the redesign as a shorter, more accurate test. A more complete explanation is that testing organizations are adapting to how AI is changing what a school can actually measure about a student’s ability.
Why test-optional admissions policies are reversing.
At the same time testing organizations were rebuilding their exams, a separate trend was unfolding on the admissions side. Several highly selective colleges spent years moving away from requiring standardized test scores. That trend is now reversing.
MIT was the first to reverse course, reinstating its testing requirement in 2022. Dartmouth followed in 2024, after its own faculty research found that test scores were the strongest predictor of student success on campus. Harvard, Yale, and Brown reinstated testing requirements within months of Dartmouth’s announcement, and additional schools have continued to join the list since.
Both trends point in the same direction. The standardized test is regaining weight in admissions decisions, and there is little indication that this reverses again in the near term.
What these tests are actually measuring now.
The specific exam a student faces changes depending on the path: the SSAT for private school admissions, the Bergen County Academies and Bergen Tech entrance exams for magnet school admissions, or the SAT and ACT for college. The underlying skill being measured does not change.
These tests evaluate a student’s ability to think clearly under pressure. That means making a good decision while the clock is running, recognizing when a question is designed as a trap, and staying steady on one difficult problem instead of losing an entire section to it. For many students, simply knowing that a test is adaptive, meaning the questions get harder or easier in real time based on their answers, adds a layer of pressure on its own. A student has to be able to adapt on the fly, not just know the content.
Built correctly, that skill pays off in three specific ways:
| Clear thinking becomes the default, so a student stops freezing on an unfamiliar question and starts working through it out of habit rather than panic. |
| Composure replaces panic, because a student who has worked through enough difficult material walks into the exam room calm instead of anxious, and that steadiness shows up directly in the score. |
| A high test score opens doors that grades alone cannot, since class rank and GPA vary widely from school to school, while a test score is the one number every admissions officer reads the same way for every applicant. |
How MEK Review prepares students for an adaptive, higher-stakes test.
At MEK Review, test prep is not built around a stack of practice tests. Instructors watch how a student takes a test: which question they linger on, where they rush, and when they talk themselves out of a right answer. After each practice section, the student sits with an instructor to talk through why they made the choices they made. That conversation, more than any additional practice test, is where a score actually moves.
Because these tests are only going to carry more weight from here, the strongest position is to build the underlying skill well before the stakes are high, not the week of the exam.
Frequently asked questions.
| Is the SAT still test-optional at most colleges. The trend is moving in the opposite direction. MIT reinstated its testing requirement in 2022, and Dartmouth, Harvard, Yale, and Brown followed by reinstating their own requirements starting in 2024. More schools are expected to follow. |
| Why did the SAT become adaptive. The College Board redesigned the SAT into a shorter, digital, adaptive exam in 2024, shifting the focus toward reasoning and inference rather than memorized content. |
| Does an adaptive test format make the SAT harder. An adaptive format changes the experience more than the underlying skill required. Because question difficulty adjusts based on a student’s answers, staying composed and making good decisions under pressure matters even more than on a fixed-format test. |
| How should a family prepare for an adaptive test. The most effective preparation builds the underlying skill, thinking clearly under pressure and recognizing traps, well ahead of the exam, rather than relying on last-minute review the week before test day. |
