PBT 290V Plant Biology & Tropical Agriculture Internship (1-4)

The course provides supervised experiential-learning with an employer. The nature of the job or project is variable but will be designed to provide opportunity for workplace experience. Maximum credit for PBT internships may not exceed 4 hours in an agricultural enterprise. The number of credits earned depends upon the number of hours spent on the job or project during the semester. PBT 290V for one credit and requires 60 to 119 hours of work; PBT 290V for two credits and requires 120 to 179 hours of work; PBT 290V for three credits and requires 180 to 239 hours of work; PBT 290V for four credits and requires 240 or more hours of work. Students can take another PBT 290V class in a subsequent semester; however, the total number of credits in PBT 290V are limited to four credits.

Prerequisite: A grade of C or better in PBT 275 or consent of instructor.
