Can you help with some recommendations to support spelling development in Year 3-6 in a small school?

We highly recommend a Direct Instruction (DI) program called Spelling Mastery. It has a 30 year study, called Project Follow Through, backing it.

It improves both teacher and student subject knowledge around spelling.
