Course delivery:
The course runs over an academic year. Home study from September - June, with two weeks of practical work and assessment at our Ryton centre in February and late May, then an online multiple-choice examination taken at home in June.
Enrolling on this course involves a commitment to a full year of study.
You will be given a structured programme which explains which topics you should work through and what course materials you need to cover each week; for seasonality this will run roughly parallel to the weekly taught courses at our centres, but of course you will have leeway to work around your local weather conditions.
You will be expected to carry out a series of tasks - in your own garden, a garden to which you have access or your place of work - and upload pictures of your work in a series of assignments to get feedback from your course tutor.
This will help you to practice and prepare for two block sessions of practical work at our Ryton centre. These weeks are designed to help you improve the techniques you have practised at home and to become proficient, ready for assessment by an external RHS examiner at the end of each week.
Online resources:
Course notes covering all the topics in the syllabus are downloadable from the online classroom (or available in printed form to purchase separately); these provide the background information for each part of the syllabus which is tested in the final online exam known as an OCA (online competence assessment).
Self-test quizzes in the online classroom will help you check your knowledge.
Narrated presentations in the online classroom cover the key points for each practical topic; there are also videos demonstrating the tasks, which with the Horticultural Standards in each section help you to identify the key points for proficiency and avoid errors in technique.
Plant identification is part of all three assessments (the PCAs and the OCA), and is supported by weekly narrated presentations with self-test quizzes to help you to learn botanical names.
Once a month there will be a plant identification test from a video of live specimens.

RHS assessments:
At the beginning of the academic year centres are told the main topic areas from within the full syllabus which may be assessed at each PCA, so the programme we devise covers these topics amongst others; some parts of the syllabus are for PCA1 the winter assessment, others for PCA2 in late spring/summer. Each PCA covers three tasks from the syllabus and a plant identification test; it is assessed by an external RHS examiner and a Centre assessor. The centre does not know the tasks until the PCAs are being prepared.
The tasks are marked according to method and proficiency; the pass mark is 50%, and this element (both PCAs combined) provides 80% of the full assessment. Dates for assessment are arranged by the RHS and the centre at the beginning of the year.
A 75-minute online test (Online Competence Assessment) is taken at home at the end of the course in June. The test is taken in line with RHS exam procedures and consists of multiple choice questions based on 'real world scenarios' of horticultural situations; it is designed to test the application of knowledge. The pass mark is 50% and this provides 20% of the assessment.
Final marks will only be awarded when both parts of the Assessment have been undertaken, but the Qualification will be graded as Pass, Merit or Distinction.
Ryton teaching weeks and practical assessments:
Dates for this cannot be altered as an RHS Assessor has to be booked at the beginning of the year for the programme.
You will come to our Ryton centre for two weeks:
Monday - Thursday 15-18 February and 31 May - 3 June will be days of practical work, designed to perfect your skills, correct any poor techniques and also to give you a chance to practise any tasks which are not easy to cover or resource at home ( e.g. planting trees or using pH and EC meters) culminating in a 'mock' PCA , working against the clock under assessment conditions. You will be given plant identification tests each day. On Friday the centre will make preparations for your two-hour PCA assessment on Saturday: PCA1 on 20th February 2027, PCA2 on 5th June 2027.
If you fail the plant identification section of a PCA you will be able to retake this online on a date set by the RHS.
If you just fail to reach the pass mark for one or two of the practical tasks, you may be able to retake them on the Sunday following the PCA so please factor this day into your travel plans. If this is not possible you will need to return to our centre on an agreed Saturday or Sunday within one month to retake the tasks.
If you fall below the basic level on two tasks, you will need to return to the centre to undertake a complete new PCA with different tasks.
All retakes will incur further RHS exam fees.
