School construction for primary education was made possible through community-based interventions. Community interventions include community-based contracting, community grants, and teacher training. Due to this approach, 400 schools were constructed with the help of villagers in the hinterlands of Lao PDR. Communities were not only able to construct permanent school structures but also led to positive and improved education outcomes. Education outcomes were evident in increasing enrolments, increased promotion rates, decreased repetition rates, increased gender parity, and higher completion rates. CBI also led to significant positive changes in social capital, community development, gender participation, build capacities in school management, better teaching-learning process and cheaper contracting costs. The intervention was not only cost-effective but was institutionalized because of collective ownership. The combination of these interventions makes CBI an appropriate approach for building communities where education is key.
