The article doesn't address the situation compared to other states. Understandable since WI is in the crosshairs of many critics at the moment. If you look at the .pdf from the Department of Education website, the same one that this article cites, you will see that Wisconsin is better than 32 states and tied with three others.

Also at the end of it Wisconsins graduation rate is consistently over 90%. Plus Wisconsin's ACT scores are also consistently among the 2nd and 3rd in the nation. If that doesn't put the issue to rest then your beef must be with teachers in general and not WI teachers.
