What's on the test, when it runs, and how to help

Guides to the NSW Selective and OC tests, NAPLAN, the ACER scholarship test, HAST and WA GATE: the format, the dates, how places are offered, and how to help at home.

  • Facts about each test come from the body that runs it — the NSW or WA education department, ACARA or ACER — and we link to them.
  • Practice questions are checked by a second reviewer, and every check is logged.
