ACCUPLACER is a series of placement tests designed to assess a student's skills in subjects like math, reading, and writing. It helps colleges and universities determine the appropriate level of courses for incoming students, ensuring they are placed in classes that match their abilities. The tests are computer-adaptive, meaning the difficulty adjusts based on the student's responses. This allows for a more accurate measurement of skills. ACCUPLACER is often used by institutions to support students in achieving academic success and to identify areas where additional support may be needed.
