The exams matter. But they are not a standalone shortcut to a Part 66 outcome

Sigma only enrols engineers into Part 66 exams once the actual outcome has been reviewed — full licence, modular licence, exclusion removal or another mapped pathway.

Start with the outcome, not the module list

Most people landing on a Part 66 exams page are not really looking for an exam sitting. They are trying to get to a licence, a modular licence, an exclusion removal or another licensing outcome.

Different outcomes need different exams

A full licence, a modular licence and an exclusion removal do not all use the same exam set.

Prior credit can change the answer

Previous MTO exams and, in some cases, CAR 31 Basics may reduce what is still required.

Exams are not the whole pathway

In a Part 147 pathway, exams sit alongside formal competency assessment against units of competency from the AQF framework.

Sigma reviews first

We do not treat Part 66 exams as a retail booking desk for people guessing their own pathway.

Apply for the outcome

Once the outcome is clear, we can tell you what exams, units or evidence are actually missing.

Why you cannot just book “the one exam I need”

Because until someone checks the whole pathway, nobody knows that it is really the one exam you need.

Under CASA’s Part 147 pathway, the route to a licence or modular licence is not just a list of module exams. CASA describes it as formalised licence category training and examination plus competency assessment. Sigma’s own licence courses combine the relevant MEA competencies with the relevant invigilated CASA module exams. Where previous MTO exams or CAR 31 Basics can be credited, Sigma sets out the exact bridging requirement on an RPL report.

That is why Sigma does not run ad hoc exam bookings for people who have made up their own pathway. If the review shows you genuinely only need one or two exams, we can enrol you in those. If the review shows you are also missing units, evidence or another module, we pick that up before you waste time on the wrong sitting.

Sigma Part 66 module exams are much clearer and straight to the point

Compared to [the other provider’s] exams, the Sigma Part 66 module exams are much clearer and straight to the point. When I studied with Sigma, I felt confident and not anxious. But with [the other provider’s] exams, even if I know I studied really well, I still felt confused about how to answer the questions, because [the other provider’s exams] don’t feel very clear, and I did not know where the questions came from.

How Sigma handles Part 66 exams

Apply first. Enrol second. Exams Third.

Apply for the actual outcome you want. That might be a full licence, a modular licence, an exclusion removal or another Part 66 pathway. We review your target outcome, previous exams, completed units and current maintenance background. Then we enrol you in what is actually missing. Sigma’s current category and modular licence courses are built this way and include the relevant invigilated CASA module exams inside the course pathway.

Once we know you’ve done everything you need, then we’ll open up our exam booking portal. Here you can book online invigilated CASA exams.

Right outcome first. Right exams second.

Sigma pathway vs CASA self-study

These are different pathways.

CASA has a separate self-study training and examination pathway. Under that pathway, the basic knowledge module exams are booked through Aspeq on CASA’s behalf, and the pathway is built around exams plus CASA practical experience logbooks. CASA also says that self-study does not cater for exclusion removal and that engineers seeking exclusion removal should contact a Part 147 MTO. Note however that the Aspeq exams aren’t always built from a common set of learning material, and aren’t always focused on the contemporary systems you’ll actually need to know in the hangar: but Sigma’s are.

So if your goal is an exclusion removal, or you want Sigma to confirm the exact gaps before you sit anything, start with the outcome page rather than a do-it-yourself module list.
