BIO-268, BIO-368 Career Exploration, Internship

Off-campus experience related to the student’s major. A limit of one course from BIO-392 or BIO-268, 368 may be used toward the Biology major and must be approved by the department in advance of the experience so that the department’s expectations are clear. See description of the Internship Program.

1. Biology students who HAVE NOT completed the Biology core sequence may register for up to 3 credits of BIO 268 when they are on an approved, semester-long internship. Biology students who HAVE completed the Biology core sequence may register for up to 3 credits of BIO 368 when they are on an approved, semester-long internship. One credit is given for 160 hours of documented time on the internship assignment and other work as assigned by the faculty sponsor. (For NIH, this would be the research assignment; the Biology department will allow at most one credit for the "NIH experience", i.e. as a participant in a study or studies.)

2. BIO 268/368 credit earned during the regular semester and to be used towards the major must be approved by the Biology department. A maximum of 1.0 credit from BIO 392 or BIO 268/368 will be allowed towards the biology major. Students planning a research internship for which they desire credit towards the Biology major must be approved by the department in advance of their research or internship experience so that the department's expectations are clear. Submission of the final results of a research project performed while on the internship is required. (January term Career Explorations cannot be used towards the major.)
