This evaluation provides an overall independent assessment of the ECHO response to the Syrian crisis in Syria, Lebanon, Jordan, Iraq, and Turkey for the period 2012-2014. It covers ECHO-funded operations in these five countries and answers a set of 18 evaluation question defined by the European Commission, which serve as a basis to reaching useful conclusions and recommendations. The evaluation is geared to a wide range of stakeholders, including ECHO Headquarters (HQ) and country level staff, national and regional stakeholders, participating implementing partners, and other humanitarian and development donors and agencies. It has both a retrospective and prospective dimension, aiming at assessing past support, but also at providing recommendations with a view to improving the performance of ECHO operations in the future.
