J-PAL has gotten a lot of attention for its unique approach to development interventions. They use the scientific randomized control trial (RCT) to test behavioral and community-based solutions and thus far have implemented or are in the process of implementing 280 of them. The group is known for their work on school attendance and teacher attendance. They have also covered such interventions as providing free eyeglasses to children in China and evaluating primary school performance (it helps) and providing microcredit in Morocco (it helped expand livestock but did not translate into enterprises).
