A couple of weeks ago USAID administrator Rajiv Shah unveiled a new Evaluation Policy, which Nancy Birdsall sees as "a big step ahead of the World Bank". 

The New USAID Evaluation Policy is Not Getting Nearly Enough Attention. It not only outlines a new policy.  It amounts to fostering a new culture, of transparency and learning.

You can watch Shah's speech, introduced by Birdsall, on Youtube. What do you think - best evaluation policy ever?
