K12 Inc. respects the work of CREDO, Mathematica, and CRPE. The online charter school study they issued affirmed much of what K12 has known about the demographics of students who transfer to full-time online schools. These students are generally more at-risk, more economically disadvantaged, and more likely to enter online charters after having struggled or failed in traditional schools. The study also made it clear that tens of thousands of students in online charter schools are succeeding. The study relies on older state standardized test data from before 2012.
However, the “virtual twin” methodology in the study, which attempts to compare performance of students who transferred to online charter schools to that of students in traditional schools, does not control or account for several key factors unique to typical full-time, statewide online public charter schools, including: persistence and performance over time, date of enrollment, the effect of mobility, and the reasons why children leave their local school.
Because the study does not include those important factors, it cannot accurately match or “twin” students who transfer to online charter schools with those who stay in traditional schools. They are very different students

Nevertheless, we understand the academic challenges that face online charter schools, and we have taken vigorous actions over the past two years to meet these challenges with results not reflected in this study. We have invested millions of dollars into new academic initiatives, instructional and assessment programs, teacher hiring and training, and student support services, all for one purpose: improving students’ academic outcomes. We are making progress, as noted in our annual Academic Report and multiple published reports on individual school progress and the effectiveness of new instructional programs. State test results have recently stabilized or improved in key areas. Several K12-managed schools have improved performance and outcomes, and perform well compared to demographically similar school districts. Students are achieving significantly better results over time, demonstrating the positive impact of persistence.
