Are used by institutions of higher education to check the academic skills or college readiness of incoming students. It is also used to determine which courses students should be required to take initially. For students who are ready to tackle college-level courses, they start out with all or mostly freshman level courses that will count towards graduation. For students who are not college ready, some or all their courses may be developmental or remedial courses, which are meant to prepare them for college-level work. The problem is that these courses do not count towards graduation, which could lengthen the duration of their matriculation.
