There are four windows a year, each running for two weeks. Registration for a window opens roughly six weeks before it starts and closes roughly three weeks before it starts. [Source: ACER, 2026]

Registration opens between 10am and 12pm on its first day, and closes at 5pm AEST or AEDT on its last. [Source: ACER, 2026]

Two things about the table are worth saying plainly. The registration period is not the test period, and the two do not overlap. And by the time a window opens, registration for it has been shut for three weeks.

The windows are spread across the year rather than bunched, which in practice puts roughly one in reach of each part of an academic year: one before first semester starts, one mid-year, one in the winter break, and one late in second semester. They do not move, and they are not extended. A window is a fortnight, and if you do not sit within it you wait for the next one.

That spacing is why a single missed deadline is expensive. The gap between windows is around three months, so missing the registration for one does not cost you a fortnight, it costs you a quarter of a year. For anyone whose placement or graduation depends on a pass, that is usually the difference between a plan working and a plan needing to be rebuilt.

ACER publishes the next year's windows partway through the current one. Where a window is listed as not yet published here, ACER has not released its dates yet, and no date exists to plan against. Check the guide online, or subscribe to the calendar so the dates land in your own when they are confirmed.

Registration closing is a hard stop, and everything else in this guide follows from it.

Deferrals to a future window are not accepted either. [Source: ACER, 2026] If you register for a window and cannot sit it, you do not move to the next one. You register again and pay again.

You can sit each component once per window. [Source: ACER, 2026] If you fail literacy in August, your next attempt is the October window, not a second go in the same fortnight. A failed component therefore costs you a whole window, not a few days.

Work backwards from the window you need rather than forwards from today. If you need a pass before a placement in March, the February window is your last realistic chance. That means registering in January, which means deciding in December, over a break when university support services are closed and nobody is chasing you about it.

The people who miss out are rarely unprepared. They are usually the ones who looked at a February test in November, judged it comfortably distant, and looked again in February.

The 2026 fee is $98.00 for a single component and $196.00 for both, GST inclusive. [Source: ACER, 2026]

The fee is payable each time you register and attempt a component, so a resit costs the same again. [Source: ACER, 2026]

The part people miss is the refund deadline, because it is not a separate date. The refund deadline is the same moment as the registration close. Withdraw before registration closes and you get the fee back less a $12 administration charge per component. Miss it and the fee is gone. [Source: ACER, 2026]

ACER is explicit that this holds regardless of circumstance: failing to schedule a remote proctoring session, not getting the test time you wanted, and personal circumstances or illness on their own do not qualify for a refund after registration has closed. [Source: ACER, 2026] The only exception is what Australian Consumer Law requires.

The administration charge is per component, so withdrawing from both costs $24 rather than $12. [Source: ACER, 2026]

You choose a delivery mode when you register, and every component you register for in the same window has to use the same one. [Source: ACER, 2026]

Combine that with the 72-hour booking rule and the effective deadline moves again: to sit remotely on the last available day you have to have booked three days before it, which is eight days before the window itself closes. If you are relying on remote proctoring, the last week of a window is not available to you in the way the published dates suggest.

Test centre sessions have their own version of the same problem. They are allocated first come, first served, so the popular times at the popular centres go to whoever registers early in the registration period rather than late. [Source: ACER, 2026] If a specific centre or a specific time of day matters to you, registering on the day registration opens is worth the effort.

Registration happens on ACER's site, not on Teacher Passport. The process is: [Source: ACER, 2026]

Your name has to match the identification you will present on the day, so enter it as it appears on your ID rather than as you usually write it. Changing your personal details afterwards is not a matter of editing a field: ACER requires you to submit evidence through your online account. [Source: ACER, 2026] Getting it right at registration is far less work than correcting it later.

Payment is what confirms the booking, not submitting the form. An unpaid registration is not a registration, and the registration close applies to the payment as much as to the rest of it.

Registration is limited to bona-fide candidates under ACER's test eligibility policy, which in practice means people enrolled in, or intending to enrol in, an initial teacher education course. [Source: ACER, 2026]

A window is not much use if you are not ready for it, and the fee is payable again on a resit. Booking the next available window because it is next is how people end up paying twice.

Find out where you actually stand first. Our free diagnostic takes about fifteen minutes and maps your strengths and gaps across both components. What it is useful for here is not the score but the decision: it tells you whether the next window is realistic or whether the one after it is the better booking, while you can still act on the answer.

Then work through free practice questions in the areas it flags, grouped by skill so you can go straight to the weak ones rather than working through everything. Both are free, neither asks for an email, and both are quicker than a resit.

If you have already sat and are waiting on a result, the timing question changes shape, because the next window may close before your result arrives. That leaves a genuinely awkward choice between registering speculatively and losing a window, and it is common enough to be worth planning for rather than discovering.
