The Associate Professional Horticulturist (APH) Certification is available to those continuing to expand their education in horticulture and experience. The APH is generally working toward an advanced degree and working to obtain greater experience. APH's can apply for the Certified Professional Horticulturist certification when education and experience are achieved.
Administered by the ASHS Certified Professional Horticultural Board, (CPHB), a CPH or APH certification is granted based on scholarly presentation, required participation in continuing education programs in particular areas of specialization, and work experience supported by references. Individuals certified by the CPHB have met educational and practical experience standards, subscribe to the CPH Code of Ethics, and qualify for identification and recognition as professionals of excellence in their field.
