About this exam

The Certificate III in Horticulture (AHC30722) is an Australian nationally recognised vocational qualification for people working, or preparing to work, in horticulture: nursery production, landscape and garden maintenance, parks and gardens, turf, and related enterprises. It suits apprentices, career changers, and existing workers who want a formal credential for skills they already use, and it is delivered by registered training organisations rather than by a single central examining board. Assessment is competency based, so it typically blends knowledge questions with practical demonstration, workplace observation, and a portfolio of evidence gathered on the job. The ten domains span workplace safety and sustainability, plant identification and botany, soils and nutrition, propagation, planting and establishment, pruning and maintenance, turf, pest and disease management, irrigation, and machinery and tools. Because the qualification is practical, the most effective preparation is hands-on: work through real tasks under supervision, keep notes and photographs, and rehearse explaining why you chose a particular technique, not just how to perform it. Pair this with the knowledge behind each task, such as reading soil test results or identifying a pest from its damage. Confirm the current packaging rules, elective choices, and assessment requirements with your RTO and the official national training regulator before enrolling.

What you'll study

Common questions

About Cert III Horticulture preparation

What does the assessment actually look like?

Most RTOs combine written or online knowledge questions with practical tasks you perform while an assessor observes, plus a portfolio of evidence such as workplace records, photographs, and supervisor reports. Some units include short answer responses. Your training provider must give you an assessment plan before you start, so ask for it early and check exactly what evidence each unit requires.

How hard is the Certificate III?

It is not designed to be academically difficult; it is designed to be practical. The challenge is breadth and consistency: remembering safety procedures, identifying plants and pests accurately, and performing tasks to a commercial standard under observation. Candidates who already work in horticulture often find the knowledge component the hardest part, while newcomers find the practical pace demanding.

How long does it take and how much does it cost?

Duration and fees vary by training provider, delivery mode, and whether you are an apprentice or existing worker, and government subsidy arrangements differ between states and territories. There is no single national figure. Check the current details directly with your chosen RTO and the official national training regulator's website before you commit.

Is there a set number of questions or a time limit?

Not nationally. Because assessment is competency based and delivered by individual RTOs, the number of questions, practical tasks, and any time limits are set by your provider's assessment tools. Ask your RTO for the assessment conditions for each unit. Do not rely on numbers quoted by other students, as they may be studying a different qualification or version.

What happens if I fail an assessment or need to retake?

Competency-based assessment lets you be reassessed. If you are not yet competent, your RTO should explain what was missing and give you the chance to practise and try again, sometimes after a gap. Specific retake rules, fees, and waiting periods are set by the provider, so confirm them in your student agreement before enrolling.

What should I study first?

Start with workplace safety and environmental sustainability, then soils and plant identification. Safety underpins every practical task, and knowing soils and plants makes propagation, planting, pruning, and pest management far easier to absorb. Leave machinery, irrigation, and turf until you have the basics, since they combine plant knowledge with technical judgement.

What are the most common reasons people struggle?

Three stand out: treating it as a purely written course and neglecting hands-on practice; weak plant identification skills, which slow down every other unit; and poor record keeping, which leaves candidates without evidence when portfolios are due. A fourth is unsafe or careless tool handling during observation. Build a habit of photographing and noting your work as you go.

Do I need to be employed or have a workplace?

Many students complete the qualification through an apprenticeship or while working for a landscaping, nursery, or council parks team, because workplace observation and evidence collection are easier there. Some RTOs offer simulated workplace environments for those without employment. Ask your provider how practical assessment will be arranged in your situation before you enrol.

How do I check that a provider and the qualification are legitimate?

Confirm the provider is registered to deliver AHC30722 and check its scope on the official national training regulator's register. Ask whether the version and elective rules are current, and request the assessment strategy in writing. A legitimate provider will answer these questions directly and will not pressure you to enrol before you have seen the details.
