Australian school teachers are among the highest paid in the OECD, earning 22 to 36 per cent more than the average – a finding that comes just after NAPLAN results showed reading, writing and grammar scores have fallen in the past 10 years, and international PISA results in science, maths and reading have collapsed since 2000.

Salaries for primary school teachers are 36 per cent higher than the OECD average, and salaries for high school teachers are 22 per cent higher.
