Well, just to elaborate on what Kevin said-----
There are some requirements for graduation, and maybe this is what Matt is asking about.
Every student transcript must document that student's didactic and clinical experience. It seems Matt is asking about the required clinical experience.
Right now the accreditation standards have been undergoing major revisions, that will take effect next year. Total number of required cases is going from 450 to 550. There will probably also be increases in the minimum number of required regionals, art lines, etc.
The transcript list is very detailed. Students must meet minimum numbers in specific categories (cranis, peds, emergency, mask cases, nasal intubations, OB deliveries, etc, etc.) It takes alot of documentation.
So, in choosing a school, it is important to make sure a program can offer enough of the required clinical experiences, so that it is not a hardship for each student to meet these minimum requirements.
