Placement testing is a practice that many colleges and universities use to assess college readiness and determine which classes a student should initially take. Since most two-year colleges have open, non-competitive admissions policies, many students are admitted without college-level academic qualifications. Placement exams or placement tests assess abilities in English, mathematics and reading; they may also be used in other disciplines such as foreign languages, computer and internet technologies, health and natural sciences. The goal is to offer low-scoring students remedial coursework (or other remediation) to prepare them for regular coursework. Historically, placement tests also served additional purposes such as providing individual instructors a prediction of each student's likely academic success, sorting students into homogeneous skill groups within the same course level and introducing students to course material. Placement testing can also serve a gatekeeper function, keeping academically challenged students from progressing into college programs, particularly in competitive admissions programs such as nursing within otherwise open-entry colleges.
Secondary schooling A placement exam is a test designed to evaluate a person's knowledge of a subject and thus determine the level most suitable for the person to begin coursework on that subject. It is not unusual for students to take a placement exam in a subject such as mathematics upon admission to a school or university to determine what level of classes they should take. Scores on such exams as the Advanced Placement, International Baccalaureate, SAT Subject Tests, and British Advanced Level exams can serve as placement tests for students in certain subjects, where a high score would enable them to get into a more advanced class than what a freshman would normally take.
Test validity In the construction of a test, subject matter experts (SMEs) construct questions that assess skills typically required of students for that content area. "Cut scores" are the minimum scores used to divide students into higher and lower level courses. SMEs sort test items into categories of appropriate difficulty, or correlate item difficulty to course levels. "Performance level descriptors" define the required skills for remedial and standard courses. Once in use, placement tests are assessed for the degree to which they predict the achievements of students once they have been assigned to remedial or standard classes. Since grades serve as a common indirect measure of student learning, in the customary analysis, a binary logistic regression is run using the test score as the independent variable, and course grades as the dependent conditions. Typically, grades of A, B or C are counted as successful, while grades of D and F are counted as unsuccessful. Grades of I (for an unconverted Incomplete) and W (a Withdrawal) may be considered unsuccessful or may be excluded from the analysis. Test scores are interpreted based on a proposed use and assessed in that context, rather than simply by establishing a predictive relationship between scores and grades. Since placement tests are designed to predict student learning in college courses, by extension they predict the need for developmental education. However, the efficacy of developmental education has been questioned in recent research studies, such as those by Bettinger and Long; Calcagno and Long; Martorell and McFarlin and Attewell, Lavin, Domina and Levey. One study found that one-quarter of students assigned to math remediation and one-third of students assigned to English remediation in the US would have passed regular university courses with a grade of at least a B without any additional support.
The placement testing process Upon enrollment a student will be recommended or required to take placement tests, usually in English or writing, in math and in reading. Testing may also include a computer-scored essay, or an English-as-a-second-language assessment. Students with disabilities may take an adaptive version, such as in an audio or braille format that is compliant with the Americans with Disabilities Act (ADA). Advisors interpret the scores and discuss course placement with the student. As a result of the placement, students may take multiple developmental courses before qualifying for college level courses. Students with the most developmental courses have the lowest odds of completing the developmental sequence or passing gatekeeper college courses such as Expository Writing or College Algebra. Adelman has shown that this is not necessarily a result of developmental education itself.
Student acceptance Many students do not understand the high-stakes nature of placement testing. Lack of preparation is also cited as a problem. According to a study by Rosenbaum, Schuetz and Foran, roughly three quarters of students surveyed say that they did not prepare for their placement tests. Once students receive their placement, they either may or must begin taking developmental classes as prerequisites to credit-bearing college level classes that count toward their degree. Most students are unaware that developmental courses do not count toward a degree. Some institutions prevent students from taking college level classes until they finish their developmental sequence(s), while others apply course prerequisites. For example, a psychology course may contain a reading prerequisite such that a student placing into developmental reading may not sign up for psychology until they complete the developmental reading requirement. Federal Student Aid programs pay for up to 30 hours of developmental coursework. Under some placement regimens and at some community colleges, low-scoring students may require more than 30 hours of such classes.
