At community colleges and open-enrollment universities, most first-year students take placement exams in English and mathematics to determine whether they are ready for college-level courses. But large-scale studies have indicated that these test scores misplace substantial numbers of students--in other words, for many students, the test score does not accurately reflect their ability to succeed in college-level courses. This fact means that many students are taking these courses when they do not need them, using up valuable time and money. To improve placement accuracy, hundreds of colleges across the country have begun implementing a strategy called multiple measures assessment (MMA), a placement approach that uses alternative indicators including high school grade point average instead of or in addition to a single test score to improve placement accuracy. Both corequisite remediation and MMA have been shown to get more students into college-level courses quickly and to help more students pass those courses. This brief summarizes findings from two surveys that show both corequisite and MMA practices are on the rise nationally, making it even more important to understand how best to implement these two practices together. This brief also introduces a study that will provide rigorous evidence related to that question.
