The city aims to add 60 charter schools in the next five years with support it's sought from the Bill & Melinda Gates Foundation. In December, the Chicago Public Schools inked a Charter-District Collaboration Compact (full 'Confidential — Not for Distribution' pdf) to allow it to compete for $40+ million in Gates Foundation funding. Needless to say, Chicago Teachers Union President and ex-HS chemistry teacher Karen Lewis is not pleased ("This will have disastrous results and people need to rise up and refuse."). So, is this a fool-me-once-shame-on-you, fool-me-twice-shame-on-me moment, or are we better off letting well-meaning billionaires continue to have at it with public education?
