Parent FAQ

Questions families ask

Is this official NAPLAN material?

No. Pi Leo Academy provides independently developed NAPLAN-style practice and is not affiliated with or endorsed by ACARA or NAPLAN.

Should my child start with timed practice?

Often it is better to find the topic gaps first, review worked solutions, then add timed practice once the skill feels familiar.

Can we try it before paying?

Yes. The free maths check-up does not require payment or a credit card.
