The Accuplacer and ACT are college enrollment/placement tests. The Accuplacer is used by community & technical colleges for placement in courses. The ACT test is most often used by 4-year colleges & universities (and many scholarships). Taking the ACT gives you options for your future as you may not know what the future holds. The majority of colleges continue to be test optional for admissions post COVID-19.
