NAATI CCL test date history, language by language

Source. NAATI's public test date search, the same list anyone can open. We ask it about each of the 55 CCL languages, one language at a time, and keep every answer.

How often. Every 2 hours since 9 Oct 2026. NAATI says its search is not live and refreshes daily, so most changes show up once a day. Checking more often does not make the data live.

Coverage. 123 of 123 scheduled checks succeeded (100%). For one language, a check counts only if NAATI answered for that language; the JSON file has the count for each language.

First seen. The first check where a session was on NAATI's list. Sessions that were already listed at our first check are marked "already listed": we don't know when NAATI added them.

Left the list. The first successful check where a session was no longer on NAATI's list. This is not proof that the session sold out or was cancelled. NAATI may stop listing a session when booking for it closes, and we can't see why a session went. If it comes back later, we count it as listed again.

Failed checks. When a request to NAATI fails, we record nothing for that language at that time. A failed check is never shown as "no sessions" or "0 seats". If a language that had sessions suddenly comes back with an empty list, we treat that check as failed unless the next check is empty too; if most languages come back empty at once, we treat the whole check as failed.

Seats. The number NAATI showed as available at that check. "Full" means NAATI listed the session with no seats available; we record it as 0. Seat numbers move both ways and can be out of date as soon as they are published. myNAATI shows what you can actually book.

Times. Session times are Sydney time, as NAATI lists them. Check times in the CSV and JSON are UTC.

Shared sessions. Some languages show exactly the same sessions and seat counts (for example Bulgarian, Czech, Finnish and 8 more). Every count here is per language, so adding counts across languages counts those sessions more than once.

What this is. A log of NAATI's public list as we saw it since 9 Oct 2026: not NAATI's booking records, not a forecast. naaticcl.com is an independent practice site, not affiliated with NAATI.
