Parent involvement is greatly influenced by the extent to which schools and teachers reach out to parents. Charter schools may be uniquely situated vis-à-vis traditional public schools to create the school organization and policies that can encourage teachers to reach out more. The authors examined the extent to which organizational and teacher-level characteristics account for cross-sector variation in teacher outreach using a matched sample of charter and traditional schools. Teacher efficacy, parent empowerment in classrooms, and home-school contracts accounted for some, but not all, of the higher levels of teacher outreach in the sample charter schools. Specific factors promoting teacher outreach were not limited to the charter sector.
