According to a new study from the National Education Policy Center (U.S.), children who enroll in a K12 Inc. cyberschool are more likely to fall behind in reading and math, move between schools or leave school altogether. This research is important as K12 Inc. is the nation’s largest virtual school company, operating 48 full-time virtual schools in 2011-12 and providing services and support to dozens of other schools that offer online classes. Some of the biggest problems the study found were K12 students’ low math scores, reading scores, and on-time graduation rates.
