In my corner of the world/philanthropy discussion, I'd consider GiveWell one of the most well-known organizations and with a reputation of high quality, thorough research. In terms of charity evaluators who focus on the impact per dollar spent, I'd have a hard time thinking of anyone comparable.

Regarding what type of programs GiveWell currently recommends, they do evaluate a wide range of types of programs. For instance, here is a page on their website summarizing some of their work on education: https://www.givewell.org/international/technical/programs/ed.... However, with the facts as they exist in the world today, their analysis is that for a given amount of funding, more good can be done with certain specific health interventions.
