This article presents questions and answers about ACT's College Readiness Benchmarks. ACT's College Readiness Benchmarks are the minimum ACT test scores required for students to have a high probability of success in credit-bearing college courses--English Composition, social sciences courses, College Algebra, or Biology. Colleges can use the Benchmarks for the ACT as one among several criteria for admission or as a foundation for determining course placement scores. States can use the Benchmarks as a tool for establishing minimum standards for high school graduation in statewide assessment contexts that are aimed at preparing high school graduates for postsecondary education. In all the above cases, the Benchmarks offer users a concise, reliable method of articulating postsecondary expectations to middle schools and high schools so that timely interventions can be made.
