The Tsunami Evaluation Coalition (TEC) is an independent, learning and accountability initiative in the humanitarian sector. It was established in February 2005 in the wake of the December 2004 Indian Ocean earthquake and tsunamis. TEC evaluations represent the most intensive study of a humanitarian response since the Rwanda multi-donor evaluation in the mid-1990s.

The TEC's three main aims are:

• To improve the quality of humanitarian action – including the linkages to longer term recovery and development – by learning lessons from the international response to the tsunami.
  
  
• To provide accountability to both donor and affected-country populations for the overall response.
  
  
• To test the TEC approach as a possible model for future joint collaborative evaluation.
