Madtown Chris, via email:

The 2007 state testing data is out and I thought I’d take another look. Again I’m looking here at Dane County area schools only compared with each other and state-wide as well. The data you will see only includes non-poor students — you can read more about why below.
Some Madison Elementary Schools are Tops
As you can see, Madison schools are simultaneously excellent and terrible. The top 8 are MMSD schools as are 6 of the bottom 10. Wow!
Not only does MMSD have top elementary schools in the area but the top 8 are above the 95% percentile statewide. That means those 8 schools are better (with respect to my measurements) than 95% of the other elementary schools in Wisconsin.
Furthermore, MMSD schools Lowell, Randall, and Van Hise are the #1, #2, and #3 elementary schools STATEWIDE. Yes you heard right. According to my ranking those are the 3 best elementary schools in the state for non-poor students.
Of the top 25 schools statewide, 7 are MMSD schools. No other area schools make the top 25.
You might consider moving to one of those attendance areas because these schools and the students in them are really, really good.
