The only impact evaluations the IDB has are beneficiary evaluations; that is, the IDB asks the beneficiaries in the communities how they evalu- ate what they received: Was it working correctly? Did they like it? Was the choice an adequate one? Was the project sustainable? The IDB study summarized about 800 project visits in various countries in which this sort of beneficiary evaluation was done, and in general, the beneficiary evaluations are quite positive. School projects have the highest evalua- tions even if a few schools that were built are not operating. Beneficia- ries give health posts a high priority, but there are problems in many areas with staffing.
