Applying for Internship Credit

After you've been hired, you can apply for enrollment in EBIO 3930 (Internship) to receive course credit if you've completed at least 9 credit hours in EBIO classes, with your grades equalling a GPA of > 2.50. No retroactive credit can be given for previous internship experience, even if that experience was with your current employer. Internship credits from other institutions do not transfer. EBIO 3930's enrollment deadline is extended to the 10th week of Fall (mid-October) and Spring (mid-March) semesters, and the 6th week of Summer Session C (mid-July). 

Enrolling in EBIO 3930 requires submitting a formal application and securing the department's permission. Key information you'll need to provide when applying includes written responses to the following prompts:

1. Position Description. Describe the nature of your position and/or your duties. What will be the most substantive aspects of your position? What will you do most of the time?
2. Educational Relevance. What do you hope to learn from this experience? How will the position help you grow as a science major, and a scientist in your field of study?
3. Learning Activities. Describe the tasks you will do in your internship (i.e., field sampling, GPS mapping, lab data collection, etc.), the ways you'll apply/further develop what you've learned in your science classes, and how those will help you move forward in preparing your career post-graduation. Conclude with a brief statement regarding the final report you will turn in when the semester/session ends (i.e., written report, research poster, babyÖ±²¥app presentation, etc.).

To help your application be successful, you should draft responses to these prompts and email Internship Faculty Sponsor Dr. Harrison Carpenter for review and feedback. If the responses fill the department’s requests, your application will be submitted electronically. 

The formal application requires you to tell how many EBIO 3930 course credits you're requesting. You may enroll for 1-6 course credits, based upon your hours of work time in your internship. For every 40 hours of work time, you can request 1 course credit (i.e., 40-79 hours of work time = 1 course credit; 80-119 hours of work time = 2 course credits, etc.). EBIO 3930 is graded Pass (P) or Fail (F). If your internship overlaps a break between semesters, you should enroll during the semester in which your internship begins; you will be given a grade of Incomplete (I) for that semester and a final grade will be given after your internship has concluded.
