„Strong evidence exists on the impact of teacher salaries on recruitment, retention and pupils’ outcomes. Higher salaries are associated with positive impacts on the recruitment and retention of better qualified teachers. Levels of teacher salaries are positively correlated with pupils’ academic performance. […] To attract and retain high-quality teachers, economists have pointed to the need to close the gap in earnings between teaching and other professions requiring a tertiary qualification.“
