The Enhanced ACT Test for UK Students
This guide covers everything UK students need to know about the ACT in 2026: format, scoring, registration logistics, and how to prepare for a competitive score.
What is the Enhanced ACT?
The ACT (originally the American College Test) is one of the two main standardised tests for US college admissions. It is administered by the ACT organisation, a US non-profit, and accepted at every US university that requires standardised testing, equally with the SAT.
The ACT measures a combination of knowledge, speed, and accuracy across three core sections (English, Math, Reading) plus optional Science and Writing sections. Top US universities use ACT scores as one important filter alongside grades, recommendations, essays, and extracurriculars.
The ACT Enhancement (September 2025)
The ACT introduced significant changes from September 2025 that made the test shorter and more flexible:
- Composite Score now based on three core sections only (English, Math, Reading)
- Science and Writing sections now optional, scored separately when taken
- Test shorter overall: the core ACT is around 2 hours 5 minutes
- From February 2026, the test also has fewer questions and shorter passages overall
Internationally, the ACT has been delivered in computer-based format since September 2018. UK students take it on the test centre's computer at one of four authorised UK test centres.
Should I take the SAT or the ACT?
The SAT is the alternative US college entrance exam, accepted equally at every US university that requires standardised testing. It has a different format, with adaptive testing across two sections (Reading and Writing, and Math) and a 1600-point composite scale. It may suit you better if you prefer a less time-pressured pace and more time per question.
For a full comparison of formats, scoring, and which test suits which student, see our SAT vs ACT guide. If you're not sure which to take, the most reliable approach is to sit a practice test of each.
How the ACT is scored
The ACT is scored on a 1 to 36 scale. Each section receives its own section score. The Composite is the average of your three core section scores (English, Math, Reading), rounded to the nearest whole number. Optional Science and Writing scores are reported separately and don't affect the Composite.
Each score is reported alongside a percentile (your rank against other test-takers).
Typical thresholds for selective US universities:
- 33+ (98th percentile or above): Ivy League, MIT, Stanford, top liberal arts colleges
- 32+ (around 95th percentile): Top-50 US universities and equivalent
- 30+ (around 90th percentile): A wide range of strong universities
- 27+ (around 75th percentile): Many competitive options remain open
Scores are evaluated alongside grades, recommendations, essays, and extracurriculars as part of holistic admissions review.
You can take the ACT multiple times. Most universities accept your highest Composite from any single sitting; many superscore (combining your highest section scores across multiple sittings). It's common for UK students to sit the ACT two or three times to optimise.
Multiple-choice scores typically arrive 2 to 4 weeks after test day, accessible through your ACT account. Some students see their scores within about a week of the test (the earliest possible release for the international computer-based ACT), while others can wait up to 8 weeks. The ACT releases scores in batches rather than all at once, so individual experience varies.
If you take the optional Writing section, those scores typically arrive 1 to 2 weeks after the multiple-choice scores (Writing requires human graders).
The ACT publishes the Initial Score Release date for each administration; that date marks when the release window begins, not when every student will reliably have their scores. See our ACT Test Dates page for current dates.
Taking the ACT in the UK
The ACT runs internationally throughout the year. UK students take it under the same international rules as students in other non-US countries.
UK test centres
See our ACT Test Centres UK page for the full list:
The ACT operates at only four UK test centres, primarily in London. This is significantly fewer than the SAT (around 25 UK centres), which makes early registration even more important.
UK test dates
See upcoming ACT test dates and deadlines:
The ACT runs seven weekend pairs per academic year internationally, typically in: September, October, December, February, April, June, and July.
Each weekend has Friday and Saturday sessions. You choose one session per administration (Friday morning, Friday afternoon, Saturday morning, or Saturday afternoon). Session availability varies by test centre.
Standard registration deadlines are typically 4 weeks before the test, with late registration available up to 2 weeks before for an additional fee.
How to register for the ACT in the UK
Register through your ACT account at my.act.org. You'll need:
- A clear, recent passport-style head-and-shoulders photo against a plain background (registration may be cancelled if your photo is rejected by the upload deadline)
- A valid ID matching your registration name
UK ACT testing is computer-based and uses the centre's equipment, so you don't need to bring your own device. Familiarise yourself with the digital interface using the practice tools on the ACT website before test day.
Because UK availability is limited (only four centres), we recommend registering as soon as your target test date is confirmed.
Your Enhanced ACT questions, answered
The ACT is a standardised test for US university admissions, administered by the ACT organisation. Since September 2018, it has been delivered in computer-based format internationally. Following the ACT Enhancement in September 2025, the Composite Score is calculated from three core sections (English, Math, Reading), with Science and Writing now optional.
The core Enhanced ACT (English, Math, Reading) takes about 2 hours 5 minutes.
Adding the optional Science section extends this to about 2 hours 45 minutes; adding both Science and Writing to about 3 hours 25 minutes.
For Ivy League and similarly competitive universities, students typically aim for composite scores of 33+ out of 36 (the 98th percentile or above). For top-50 US universities, 32+ is a strong target. Scores of 30+ keep options open at many strong universities. Scores are evaluated alongside grades, recommendations, essays, and extracurriculars.
We generally recommend taking Science, particularly for STEM applications. Strong Science scores demonstrate scientific reasoning ability that the SAT can't capture, and several universities still expect to see it. We don't usually recommend Writing unless a specific target university explicitly requires it.
The ACT runs seven weekend pairs per academic year internationally, typically in September, October, December, February, April, June, and July. Each weekend has Friday and Saturday sessions. UK students usually sit it once or twice in Year 12. See our ACT Test Dates page for upcoming dates.
The ACT is offered at only four UK test centres, primarily in London. Because spaces are limited, we recommend registering as soon as your target date is confirmed. See our ACT Test Centres UK page for the full list.
Register through your ACT account at my.act.org. You'll need a passport-style photo and a valid ID. Because UK availability is limited (only four centres), we recommend registering at least 8 to 10 weeks before your target date.
Both tests are accepted equally at every US university. The choice comes down to which format suits your strengths. The ACT is fixed-difficulty with faster pacing and an optional Science section; the SAT is adaptive with a more relaxed pace per question. See our SAT vs ACT guide for a full comparison, or take a free practice test of each on our diagnostic page.
Yes, several leading European universities that teach in English accept the ACT for international applicants, including Bocconi University (Italy), IE University (Spain), ESADE Business School (Spain), HEC Paris (France), and the University of St. Gallen (Switzerland). However, the SAT is the more commonly submitted test for these European programmes; ACT submissions are accepted but less typical. Each programme has its own admissions requirements, so check the specific university and degree.
We generally advise UK students to begin ACT preparation in the summer after Year 11, with the goal of sitting the test for the first time in the autumn term of Year 12 (or the spring term of Year 12 if necessary). We strongly recommend completing all ACT testing by the summer after Year 12, so that the summer and Year 13 are free for other application elements and schoolwork.
