What an assessment for HLTARO002 must cover

34 assessable components: 5 elements (17 performance criteria), 3 performance evidence and 14 knowledge evidence requirements. An audit-defensible tool maps every question and task back to these — that mapping is the coverage matrix Auditori generates alongside the assessment.

Performance evidence

investigated and confirmed reliable sources of natural and manufactured aromatherapy products
followed preparation processes that meet pharmaceutical guidelines and legal requirements for at least 20 different aromatherapy products: checked materials and equipment, followed processes that protect integrity of the product, made accurate calculations and measurements, packaged and accurately labelled products, completed accurate documentation
prepared different product types, including all of the following at least 3 times: creams, ointments, lotions, oil blends, tinctures, extracts, gels, balms

Knowledge evidence

legal and ethical considerations (national and state/territory) for the preparation and supply of aromatherapy products: Therapeutic Goods Administration (TGA) guidelines, labelling, principles of manufacturing, quality control procedures, records management, work health and safety – hazards and controls for aromatherapy products
chemistry fundamentals used in aromatic therapy product preparation: classification of substances, understanding matter, chemical reactions, atomic structure, elements and the periodic table, molecules, molecular formula and compounds, bonding, isoprene units, variability in carbon-based molecular structure, name and structure of functional groups, alcohols, phenols, aldehydes, ketones, acids, esters, ethers, solubility and the differences between hydrophilic, hydrophobic, lipophilic and lipophobic
sources of aromatherapy ingredients and products and methods to determine quality of supplies
plant identification systems: common names, synonym, botanical names, plant families
essences and how they relate to plant materials
processes used to obtain aromatic material: extraction methods, distillation, cohabation, rectification
differences between essential oils and carrier oils
origins, chemical components, properties and uses of at least 60 essential oils, including interactions and synergies: odiferousity, volatility, flammability, concentration, viscosity, lipophilicity
origins, chemical components, properties and uses of at least 15 carrier oils: grading process, how they are used as additives, extraction methods
features of other mediums used as carrier oils in aromatherapy: alcohol, clay, creams, dispersants, gels, hydrosols, macerations, lotions, ointments, tinctures, water
techniques to prepare aromatherapy products from source materials, including: creams, ointments, lotions, oil blends, tinctures, extracts, gels, balms

Questions about assessing HLTARO002

What does an assessment tool for HLTARO002 need to cover?

To satisfy the Principles of Assessment and Rules of Evidence, an assessment for HLTARO002 needs to address all 34 unit components: 5 elements with 17 performance criteria, 3 performance evidence requirements, 14 knowledge evidence requirements, and the foundation skills. A coverage matrix mapping each question and task to these components is what an auditor looks for.

How does Auditori generate an assessment tool for HLTARO002?

Auditori pulls the current release of HLTARO002 from training.gov.au and generates a complete package: candidate assessment, assessor guide with model answers and observation criteria, and a coverage matrix mapping every component. A suitably qualified person then reviews and approves the draft in a built-in workflow — consistent with ASQA's guidance on AI use in VET — before export as branded PDF and editable Word.

Is the first assessment tool really free?

Yes. Every new account includes one free credit — enough to generate the complete assessment tool for HLTARO002 — with no card and no subscription required. After that it's pay-as-you-go per unit.

Can I check my existing HLTARO002 assessment instead of generating a new one?

Yes — upload your existing assessment or learner guide and Auditori maps it against every element, performance criterion, PE and KE of HLTARO002, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
