ENTRi is an initiative funded by the European Commission (90%) and co-funded by its 14 implementing partners under the lead of the Center for International Peace Operations (ZIF) in Berlin. The programme began in 2011 and is set to run until March 2016. The total budget of the programme since its inception is 5.8 million Euro. The implementing partners are from different Member States of the European Union and Switzerland. ENTRi was created by the European Union’s Instrument contributing to Stability and Peace and is guided by the European Commission's Service for Foreign Policy Instruments (FPI), which is co-located with the European External Action Service.

So far, 1450 individuals of 76 different nationalities were trained in a total of 67 ENTRi courses.
