„Existing research points to two main determinants of teacher retention. The first is the nature of working conditions in teachers’ schools. Working conditions are strongly associated with retention, particularly for early-career teachers. Quantitative research using teacher survey data suggests that – among the various aspects of working conditions – the nature of school leadership has a particularly strong association with both job satisfaction and retention. Other aspects of working conditions which have been linked with retention include pupil behaviour, teacher collaboration and workload. The second important determinant of teacher attrition is pay. This has been demonstrated in studies using observational data in which pay varies over school districts as well as in quasi-experimental evaluations of policies that have increased pay for specific groups of teachers.“
