Teachers’ compensation includes their basic salary, annuities based on years of service, surcharges (overtime pay for other activities) and incentives (professional career, annual increases, location of school and others). Surcharges and incentives jointly account for 70% of the base salary (MEP, 2016). Teacher remuneration has significantly improved in recent years, particularly for experienced teachers with a permanent contract, and this partly explains the increase of spending in primary education at a time of falling student numbers (PEN, 2015).
