The study investigated how policy intervention could have significant impact on beneficiaries. Using quasi-experimental design, 360 pupils from participating and non-participating schools in a feeding program were selected from a rural setting. Instrument for data collection was validated, pre-tested and administered on cross-section of respondents. Data were analyzed using descriptive statistics, t-test and regression analyses. Findings show that significant differences existed in educational outcomes as participating pupils performed better in core subjects of English Language, Mathematics and Integrated Science. In terms of socioeconomic determinants, findings show that selected variables such as sex of pupils and number of dependents in the family had directly impacted on the performance of pupils. The study also found causal link between the school feeding intervention and others as one of the multiplier effects was not only an increased enrolments by almost a quarter, but reduced dropout and absenteeism rates. This implied that the policy environments was sufficiently pro-poor and effective since it has strengthened the standard of foundational primary school and completion rate envisaged in the educational policy. It is recommended that further policy options that would facilitate the scaling-up of the program in the entire intervention area be formulated.
