  • Credit-by-Exam (CBE) is a testing program offered by the San Marcos CISD ISD for enrolled students in grades Kindergarten through 12. The purpose of CBE testing can be for acceleration (a student wishing to test out of a grade level or course without having had prior instruction), validation of home school or non-accredited private or public school credit when other methods are not available, or recovery of credit for a failed course.
