Grow Your Expertise with AHTA-Accredited Education.
What is an AHTA Accredited Certificate Program?
An AHTA Accredited Certificate Program is a college-level educational program that offers the equivalent of nine (9) semester credits in horticultural therapy coursework. The AHTA accredited certificate programs provide a foundation in the theory and application of horticultural therapy for diverse populations.
An AHTA Accredited Certificate Program is one that has applied for and received accreditation status by AHTA. The AHTA Certificate Program must maintain accreditation based on the standards set by the Association.
Accreditation ensures that horticultural therapy certificate programs meet nationally endorsed standards in the profession.
Certificate programs accredited by AHTA offer all nine (9) semester credit hours within their educational program.
Coursework & Educational Requirements
An AHTA Accredited Certificate Program provides course content that fulfills the requirements for professional registration with AHTA. An AHTA Accredited Certificate Program may be offered as a component of an academic degree program to fulfill the requirements of a degree in horticulture with a concentration in horticultural therapy.
To meet the requirements for professional registration with AHTA, horticultural therapy coursework completed as part of the certificate program, independent of bachelor’s/master’s degree, must be from an AHTA Accredited Certificate Program.
Note: Graduates of certificate programs are not ‘certified’ horticultural therapists. They receive a certificate of completion of horticultural therapy coursework which, if accompanied by the affiliated college or university transcript, will be required should they pursue professional registration with AHTA.

Beyond the Classroom: Internships & Registration
A 480-hour horticultural therapy internship is a required component for AHTA Professional Registration. These internships provide essential hands-on experience, allowing students to apply theory and practice as clinicians, educators, and technicians in a variety of settings. All interns are supervised by a registered horticultural therapist (HTR or HTM) to ensure the development of professional competency.
