In addition to the background check required by CBC, each clinical facility reserves the right to conduct its own criminal background check prior to allowing a student to enter its health care facilities for clinical participation.

Certain criminal convictions, pending charges, or negative actions may automatically disqualify a person from having unsupervised access to vulnerable adults, juveniles and children. Clinical facilities reserve the right to accept or decline a student’s placement in its facility.
