Standardized Tests

Why the SAT, ACT, and ASVAB matter, what they cover, and how to register from Guam. Last reviewed: August 15, 2026

Why Standardized Tests Matter

Most U.S. colleges and universities, including many off-island schools Guam students apply to, use standardized test scores alongside GPA and coursework to evaluate applicants. Some schools are "test-optional," but a strong score can still strengthen an application, unlock merit scholarships, or offset a lower GPA. The ASVAB serves a different purpose: it's used for military enlistment qualification and career placement, not college admissions, but it's still a standardized test many Guam students take in high school.

The SAT

The SAT is a college admissions test covering Reading and Writing and Math, scored on a 400–1600 scale. It's widely accepted by colleges nationwide, including the University of Guam and most mainland U.S. schools. Many students take it once in the spring of junior year and again in the fall of senior year to try to improve their score.

The ACT

The ACT covers English, Math, Reading, and Science, with an optional Writing section, scored on a 1–36 scale. Colleges generally accept the SAT and ACT equally. The right choice depends on which format fits you better (the ACT is more fast-paced and includes a science reasoning section; the SAT gives slightly more time per question).

The ASVAB

The Armed Services Vocational Aptitude Battery (ASVAB) is used to determine eligibility for U.S. military enlistment and to match recruits with military job specialties. It's offered free through many Guam high schools via the school counselor's office or a recruiter, and it can be useful to take even if you're unsure about military service. It gives you a sense of your aptitudes and is not a binding commitment to enlist.

Registering From Guam

  • SAT: register online at collegeboard.org and select a Guam test center when scheduling.
  • ACT: register online at act.org; confirm a nearby test center is listed for your preferred date, as availability on Guam can be limited.
  • ASVAB: ask your high school counselor about the school's next ASVAB testing date, or contact a local military recruiting office directly.
  • Fee waivers: students with financial need may qualify for SAT/ACT fee waivers. Ask your school counselor before paying out of pocket.
