ADL is an Approved RHS Distance Learning Provider. RHS qualifications are recognised nationally and internationally, and are held in high regard by the global horticultural community.

ADL RHS courses, specifically focus on helping you to pass the RHS exams first time. They were developed by horticultural professionals experienced in the RHS syllabus.

Please Note: If you are considering the RHS Level 3 Diploma as your ultimate qualification, you can start by completing all the Level 2’s and Level 3 certificate theory courses online with ADL. You then complete the practical courses (face-to-face) at an RHS approved college near you.

Completing all online theory courses with ADL first, will help reduce your overall tuition fees, rather than completing the theory courses elsewhere in a face-to-face classroom.
