Most schools or organizations that give assessment tests let students retake the exam within certain guidelines. Purdue University, for example, gives a math assessment test to students and then gives them the opportunity to retake the exam five times. The highest score is then used to meet requirements of different math courses.
Other schools use the same test, the "ALEK Math assessment Test," to measure the abilities of students interested in taking higher level math courses. The test is part of McGraw Hill online learning resources, which provides standards that a student can use to measure strengths and weaknesses. McGraw Hill also offers a personalized learning module online that can be studied before retaking the test.
