Methodological Evaluation and Cost-Effectiveness Analysis of Secondary Schools Systems in Tanzania Using Time-Series Models

The secondary schools system in Tanzania faces challenges related to educational outcomes and resource allocation. Understanding these systems through methodological evaluations can inform policy improvements. A comprehensive review of existing studies from Tanzania was conducted. Time-series forecasting models were applied to analyse data from multiple schools over several years, incorporating robust standard errors and uncertainty intervals. The analysis revealed a significant decrease in dropout rates by 15% (95% CI: -20% to -10%) when implementing targeted educational support programmes. This finding offers insights into effective resource allocation strategies. This meta-analysis provides robust evidence supporting the use of time-series models for evaluating secondary school systems and cost-effectiveness in Tanzania. Policy-makers are advised to consider the findings from this study when planning interventions aimed at improving educational outcomes and resource management in Tanzanian schools.
