The other model is a full-time online charter school like the Wisconsin Virtual Academy. About 90,000 children get their education from one of 185 such schools nationwide. They are publicly financed, mostly elementary and middle schools.

Many parents attracted to online charters have previously home-schooled their children, including Mrs. Weldie. Her children—Isabel, Harry and Eleanor, all in elementary school—download assignments and communicate intermittently with their certified teachers over the Internet, but they also read story books, write in workbooks and do arithmetic at a table in their basement. Legally, they are considered public school students, not home-schoolers, because their online schools are taxpayer-financed and subject to federal testing requirements.

Despite enthusiastic support from parents, the schools have met with opposition from some educators, who say elementary students may be too young for Internet learning, and from teachers, unions and school boards, partly because they divert state payments from the online student’s home district.

Other opposition has arisen because many online charters contract with for-profit companies to provide their courses. The Wisconsin academy, for example, is run by the tiny Northern Ozaukee School District, north of Milwaukee, in close partnership with K12 Inc., which works with similar schools in 17 states.

The district receives annual state payments of $6,050 for each of its 800 students, which it uses to pay teachers and buy its online curriculum from K12.

Saying he suspected “corporate profiteering” in online schooling, State Senator John Lehman, a Democrat who is chairman of the education committee, last month proposed cutting the payments to virtual schools to $3,000 per student. But during legislative negotiations, that proposal was dropped.
