 Key features:

Teachers’ and school heads’ salaries and allowances is a yearly data collection.

Data are collected jointly by:

EACEA and the OECD secretariat undertake a joint cleaning phase to clarify with countries belonging to the two networks any remaining issues.
For countries, which do not participate in NESLI, the cleaning phase is managed by EACEA solely. For this visualization tool, all data sets and texts are prepared by EACEA and checked by the Eurydice national units.

Any divergence to definitions or national specificities important to understand data are available in the country-specific notes.
All information is collected according to the International standard classification of education (ISCED 2011).

All salary data is collected in the national currency.

Use of Eurostat data:

Salaries' conversions are calculated based on Eurostat datasets:

  • Euro/ECU exchange rates to convert salaries in national currency into euros
    ([ERT_BIL_EUR]; time frequency: annual; statistical information: average; unit of measure: national currency) 
  • Purchasing power parities (PPPs) to calculate salaries in purchasing power standard (PPS) and thus facilitate international comparison ([PRC_PPP_IND_1]; Purchasing power parities, price level indices, nominal and real expenditures by analytical categories - based on COICOP 2018: purchasing power parities (EU27_2020=1); Analytical categories for purchasing power parities (PPPs) calculation: actual individual consumption) 
  • Harmonized index of consumer prices (HICP) to calculate salaries at constant prices for trends to adjust for the effects of inflation, using the HICP rate Harmonised index of consumer prices (HICP) - ECOICOP ver.2 - indices and rates of change, annual data ([PRC_HICP_AINR]; time frequency: annual; unit of measure: annual average index; classification of individual consumption by purpose (COICOP): all-items HICP).
