School of One is an online program that was piloted in 3 schools.
Two of the three schools have dropped it, but the Bloomberg administration plans to expand it to more schools.
School of One was developed by Joel Rose, who was TFA, Broad Academy, Edison, then worked for Chis Cerf and Joel Klein at the NYC Department of Education. The NYC Parent Blog describes the history of the School of One here and points to some important ethical issues.
Time magazine cited School of One as one of the best inventions of 2009, before it was implemented.
It won a $5 million grant from the US Department of Education as one of the most innovative programs in the nation.
The city put $9 million into the program so far, and previously projected the cost at $46 million. It will be added to four more schools, with the help of the federal grant.
