A theory-based qualification to improve the horticultural knowledge needed for career development to supervisory or management roles, or to further develop your interest.
Whilst there are no formal prerequisites for entry to the qualification, it is strongly recommended that students who undertake this qualification have obtained the RHS Level 2 Certificate in the Principles of Plant Growth, Propagation and Development or equivalent before they commence on the course.
Where a candidate receives commendations in all four mandatory units, the qualification will be awarded with commendation.
Each unit will be assessed by a separate written examination covering all learning outcomes specified in the unit. Examinations will be offered twice a year in February and June.
