CARPENTERSVILLE – The online curriculum company that could oversee the day-to-day operations of a proposed online charter school throughout the Fox Valley has drawn many critics skeptical of the company’s for-profit status.

K12 Inc., a Virginia-based company that has developed and managed virtual learning schools across 27 states, has endured a firestorm from critics, who argue the company siphons tax dollars from public schools and has yet to produce superior academic results in the face of increasing profit margins.

The company soon could be used in the Fox Valley region, after the newly formed Illinois Virtual Learning Solutions recently proposed to start an online charter school for underserved students in 18 school districts, including Carpentersville-based District 300.
