What does 'the programming series of classes does not comply with the Carnegie system of credit measurement' mean?

The Carnegie system awards 1 credit per 50 or 55 minute class session per week over the course of a semester. I assume the statement means there is more (or less) class time required for the programming courses. It may be that the courses are "stacked" or offered in another alternative delivery format. To be sure, ask the program representative.
