Horticulture internship

Because horticulture is a very applied discipline, it is important for you to gain hands-on field experience in order to successfully use the knowledge you gain from your classes. As part of your studies, you will be required to complete a 360-hour internship.

The internship will be especially important because employers look for graduates who have shown that they can apply academic knowledge to the practical field of horticulture. OSU's Department of Horticulture encourages you to find as many opportunities to work in the field as you can during your time in school.

NOTE: If you are currently working in the horticultural industry, you may be able to use your employment to meet the internship requirement.

Transfer credit

Some of the degree requirements can be transferred from other colleges and universities. Please note that a minimum of 45 credits of the last 75 must be completed at Oregon State (online or on campus) to meet the academic residency requirement. Previously earned credits will need to be reviewed upon admittance into OSU for appropriate articulation. Additional information about transferring credits is available through the single course search tool provided by OSU's Office of Admissions.
