AG 293V 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. AG 293V for one credit and requires 60 to 119 hours of work; AG 293V for two credits and requires 120 to 179 hours of work; AG 293V for three credits and requires 180 to 239 hours of work; AG 293V for four credits and requires 240 or more hours of work. Students can take another AG 293V class in a subsequent semester; however, the total number of credits in AG 293V are limited to four credits.

Prerequisite: Instructor approval.

Rec Prep: At least two of the 200 level PBT courses.
