This presentation will report on a study using rigorous economic methods to compare investments in five specific approaches to increasing high school completion and the resultant returns to the taxpayer. Costs of the five approaches are measured directly by their resource requirements. Benefits of high school completion to the taxpayer are evaluated in terms of additional tax revenues and lower costs of crime, public health, and public assistance. Each additional graduate not only generates large personal benefits but confers a net gift (after costs) to the taxpayer of about $127,000. Come hear about this study.
