Conducted for Arnold Ventures by Abt Global, the New Mexico Charter School Study: Findings Report collates the results of Abt’s evaluation of numerous charter schools in the state, several of which employ a whole-school dual language model. The study also created multiple logic models for use by practitioners, policymakers, and researchers, and led to ideas for making enrollment in charters schools more equitable.

Among the findings: the most rigorous analysis, a lottery study, found no statistically significant impacts on measured student academic outcomes for elementary-aged and middle school-aged students, nor on college enrollment for high school-aged students.  However, the less rigorous analysis–a quasi-experimental study–had mixed results, suggesting high school charters increased college enrollment and elementary charters reduced mathematics achievement.
