„Singapore uses a manpower planning approach so that every teacher trainee who is recruited and selected for training is paid by the Ministry of Education during their initial teacher education and then has a guaranteed first job. The Singapore career structure has three career tracks – the master teacher track, school leader track, and specialist track – so that if teachers enjoy teaching they can advance professionally and financially within teaching, but if they don’t enjoy teaching they can find other paths within education.“
