The ACT is a genuinely global test -- it's administered at authorized test centers in more than 100 countries, and U.S. colleges accept scores from international test dates exactly the same as scores from a domestic one.
Where it's offered
Outside the U.S. and Canada, the ACT is delivered exclusively as a computer-based exam, offered internationally 5 to 7 times per year -- fewer dates than the U.S. testing calendar, so international test-takers need to plan around a more limited schedule. Check ACT's own international registration site for the current test dates and authorized center locations available in your country.

What registration actually requires
International registration has a few requirements that differ from domestic registration: a valid passport is required for identification -- a national ID card or driver's license is not accepted, unlike some domestic registration options. You'll also need a passport-style photo meeting ACT's specific formatting requirements, and a credit or debit card for payment, since international registration is completed online directly through ACT's international site.
One real cost difference worth knowing
Fee waivers -- financial assistance that reduces or eliminates the ACT registration fee for eligible students -- are only available for students testing within the U.S., U.S. territories, or Puerto Rico. Both U.S. citizens and foreign nationals testing at a location outside the U.S. are not eligible for a fee waiver, regardless of financial need, so budget for the full registration cost if you're testing internationally.
How your score is treated
Once you have a score, it's treated identically to a domestic score by every college that accepts the ACT -- your score report doesn't indicate whether you tested domestically or internationally, and colleges don't apply a different standard based on testing location. The same superscoring and Score Choice policies described elsewhere on this site apply equally to international test-takers, set individually by each college regardless of where you tested.
Practical planning advice
Because international test dates are less frequent than the U.S. calendar, build extra buffer time into your application timeline -- a single missed or canceled international test date can mean a multi-month wait for the next available one, in a way that's less likely with the more frequent U.S. schedule. Confirm your specific country's available test centers and dates directly on ACT's international site well before you plan to apply, since availability can vary significantly by region.
