Kettering University is eliminating 500 course numbers due to HLC concerns about our graduate program. Since our 500 level courses are defined as "mezzanine" they are not considered to be graduate courses by HLC. This puts a limit on how many 500 level courses a graduate student can take in the graduate program. According to HLC they cannot take more than five 500 courses. The Course Number is being changed to MECH-426 so there is no confusion about the level of the course.
