External Learning Experiences
This program includes external learning experiences outside of the classroom, e.g., an internship, externship, clinical, practicum, or cooperative learning experience. Those experiences are typically on‑site at a business or organization.
All students participating in external learning experiences are required to comply with the immunization requirements and policies of the external learning sites. Some learning sites outside the college have their own vaccination requirements. These rules come from those facilities and are not mandated by the college. Failure to meet those immunization requirements may limit a student’s ability to complete the program and/or may delay the student’s graduation date. San Jacinto College does not process exemptions, and students should address potential vaccination exemptions directly with the external learning site.
