Key Findings:

• Student–driven, independent study is the dominant mode of learning in online charter schools, with 33 percent of online charter schools offering only self-paced instruction
• Online charter schools typically provide students with less live teacher contact time in a week than students in conventional schools have in a day
• Maintaining student engagement in this environment of limited student-teacher interaction is considered the greatest challenge by far, identified by online charter school principals nearly three times as often as any other challenge
• Online charter schools place significant expectations on parents, perhaps to compensate for limited student-teacher interaction, with 43, 56 , and 78 percent of online charters at the high school, middle, and elementary grade levels, respectively, expecting parents to actively participate in student instruction
• These findings suggest reason for concern about whether the online charter school sector is likely to be effective in promoting the achievement of its students
