Frequently asked questions
What's a good NAPLAN score for schools in St Marys?
There is no suburb-specific official benchmark for “good”. A reasonable first read is to compare each school with the broader national range and then, more importantly, with schools at similar ICSEA. In St Marys, some schools sit well above the national Year 5 average, but that does not automatically tell you whether they are adding more value than a lower-scoring school with a very different intake profile.
How do I check the school catchment for St Marys?
Open a school from the table and inspect it in the map view. Where department or ACARA-linked catchment data is available, that is the best starting point. Catchment boundaries can change, though, so the cautious step is to confirm with the relevant education authority or the school before relying on it.
Which is the best primary school in St Marys?
There is no single factual answer to that. The table is sorted by latest NAPLAN mean, which is useful for orientation, but a family could still reasonably prefer a different school because of sector, fees, language offering, learning support, distance, or culture. This page is best used to narrow the field, not to end the decision.
