Four or five agencies submit themselves to independent evaluation per appeal, are used to assess their effectiveness in responding to disasters and are generally carried out within a year of an appeal.


RTEs used to assess how well a disaster response is going and whether anything needs to be changed or improved for the remainder of the relief effort.

We also use the knowledge we gain from these to adapt the way we work, as part of our DECAF process of continuous improvement.

They are conducted within six months – early enough to influence the way the response is evolving – and are carried out by independent consultants, although a member of the DEC secretariat or one of our member agencies could also be involved.


These are studies and reviews conducted around a theme – such as what aid workers learned from delivering a disaster response in densely populated urban areas following the 2010 Haiti earthquake [3.5mb pdf], or post-disaster reconstruction and resilience-building following the 2004 Asia tsunami [7mb pdf].

They concentrate on learning lessons from our programmes to help improve disaster responses in the future and gathering knowledge that may also be used for the humanitarian relief sector in general.

The DEC’s performance is evaluated in its annual report.
