Query: Elusive Longer-Run Impacts of Head Start: Replications Within and Across
  Cohorts   Using an additional decade of CNLSY data, this study replicated and extended
Deming's (2009) evaluation of Head Start's life-cycle skill formation impacts
in three ways. Extending the measurement interval for Deming's adulthood
outcomes, we found no statistically significant impacts on earnings and mixed
evidence of impacts on other adult outcomes. Applying Deming's sibling
comparison framework to more recent birth cohorts born to CNLSY mothers
revealed mostly negative Head Start impacts. Combining all cohorts shows
generally null impacts on school-age and early adulthood outcomes.
