Horticultural Technology

Landscape Operations Diploma Program

The Thompson School has a program leading to a Diploma in Landscape Horticulture. This day program is open to part-time students who want to concentrate in landscaping and obtain a credential, but who are not matriculated in a degree program at the Thompson School or elsewhere within the University.

The UNH Thompson School is well-known for its strong career-oriented programs which provide a combination of theoretical classroom and practical in-the-field education. This Diploma program in Landscape Horticulture draws upon these Thompson School strengths to prepare individuals for career entry-level employment in landscape design, construction, and maintenance. Students in this program will find their talents challenged and developed by a faculty concerned with student learning. Students will be able to apply the skills and knowledge they learn to a variety of settings. If a student is accepted for admission to the Thompson School Associate in Applied Science (AAS) degree in Horticultural Technology, credits earned in the Diploma Program are transferable.

Transfer Credits

Due to the small number of courses required for the diploma, normally only one course (up to 4 credit hours) will be accepted in transfer from other colleges. This course must be similar in content to a required diploma course, must be at least a 2-credit course, and must have been completed with a C (2.00) or better grade. Students who believe they have courses that might be transferable should discuss this with the Curriculum Chair in Horticultural Technology or with their assigned faculty advisor.
