A new report’s found a further $6 billion is needed for public schools annually in order to meet the minimum standards states have committed to in the Gonski funding model.

The Australia Institute report also found that students from disadvantaged socio-economic, regional and Indigenous backgrounds were likely to suffer the most.

The report’s author Dr Jim Stanford has told the ABC, the research shows the effects of a poorly funded school system.

The latest NAPLAN results show fewer than 30 per cent of students in very remote schools rated as “strong” or “exceeding” in literacy and numeracy.

Nationally, one in 10 students across all grades were found to need extra support, while on average a third of all Indigenous students were in that category.
