The Horticultural Therapy Institute recognizes that certificates are increasingly used by employers and clients as validation of special skills and knowledge. Earning a certificate demonstrates both initiative and willingness to make the time commitment necessary for both professional and career development. Certificates offer the possibility to study a concentrated area such as horticultural therapy without the expense or time commitment of obtaining an entire degree. If you are ready to advance your career or become an expert in this emerging field, the HT certificate program can open the door for you to pursue your goals.
The certificate program can be completed within one year. It consists of four courses, each in a four or five-day intensive format. Face-to-face learning is supplemented with out-of-class assignments and projects students complete at a distance. We at the Institute believe in the value of face-to-face interaction in this high-touch profession. While in class students work on group projects and problem solving, discussion of the heart of the human/nature connection as well as engage in networking with other students. The first step is for students to enroll in Fundamentals of Horticultural Therapy. This class is a prerequisite for the other classes in the certificate program. Because each of the courses builds upon experiences and information from preceding ones, the ideal approach is to enroll in them sequentially. We do work with students individually if it is necessary to take a course out of sequence. Payment for each class is due by the enrollment deadline. The American Horticultural Therapy Association accredits the HT certificate. Each course is also approved for academic credit from Colorado State University. See the course schedule for more details. The optional credits are discussed in class and payment made at that time.
Courses at the Institute are available for academic credit through Colorado State University. Students may earn a total of 9 credits in horticultural therapy, as required by the AHTA standards for professional registration. These credits are optional for certificate students, but required for those seeking professional registration.
HTI students who are not currently enrolled at CSU have the option of signing up for credit during the class session through CSU Division of Continuing Education. No admission procedure is required. Students fill out the forms during class and pay additional fees to CSU for credits at that time.

Currently, there are no legal requirements for HT credentials in the U.S. However, becoming professionally registered helps both the professional and the profession by demonstrating a knowledge base for successful and effective horticultural therapy practice.
Generally, the curriculum at the Institute is designed for completing the classes in order. Each course builds upon the previous one(s) in content and assignments. Requests to enroll in a class without the prerequisites should be directed to the lead instructor, and will be considered individually.
Substitutions may or may not meet the Institute’s prerequisites for enrollment. Each request to do so is considered individually. To maintain the HT Institute’s AHTA accreditation, a certificate in horticultural therapy is only issued to those who complete all four classes at the Institute.
No, the reason our classes are held in four or five day intensive formats is to allow students to travel to the class site from any location.
Depending upon where classes are held, the Institute generally tries to obtain a group rate for lodging or recommendations for lodging. More information can be found on our Accommodations page.
Yes, for most courses, you need at least one book or professional journal. We use the same two textbooks for all advanced courses. In addition, you may need access to a journal on horticultural therapy or an additional book to prepare for assignments. These are specified on your enrollment confirmation for each class.
Occasionally we have funding to award partial scholarships for advanced classes upon request.
