The impact evaluation followed a time series control group design, with baseline, midterm, and final endline surveys conducted in treatment and comparison municipalities. The treatment group consisted of beneficiary municipalities, while the comparison group was chosen from municipalities within the same sample provinces with similar characteristics to the treatment municipalities, but not receiving project support. 8 Given that the evaluation was not part of the original project design, alternative evaluation designs (such as random assignment) were ruled out. The treatment municipalities were drawn from among the poorest quartile municipalities in the beneficiary provinces supported under Phase III-A of the project. In this way, it is expected that these areas would have benefited from lessons learned from early phases of project implementation.
Project implementation in Phase III-A municipalities started in October 2004. The sample provinces were chosen to represent the distribution of beneficiaries by island group: Albay in Luzon, Capiz in Visayas, and Zamboanga del Sur and Agusan del Sur in Mindanao. In addition, in two of the provinces (Albay and Agusan del Sur) qualitative data were collected in 2005 and 2010.
