(Guest Post by Matthew Ladner)
So I went through the Arizona Board of Regents report on college graduation by high-school some more, and looked this time at the bottom to see whether charter schools were over-represented at the bottom as well as the top. A few caveats I eliminated alternative high schools from the list, as these schools are basically dropout recovery programs. Second, there is a lot of missing data for a lot of high schools, so this may not be the actual bottom 10, more like the bottom 10 for the schools we have data on. Another * goes to Metro Tech which is teaching career and technical skills which might keep graduates gainfully too busy to finish college in a six-year span (although many CTE students do eventually earn college degrees). Metro Tech may be great or it may leave a lot to be desired but I would not conclude much of anything from their place on this list.
My method for eliminating alternative schools was to look at the oldest available list from the Arizona Department of Education, having said that when you look at the website for the International Commerce High School it mentions serving adult high school students and my spidey sense tells me that it is an alternative school. The other charter school on the list (delightfully imo) closed.
Regular ole district high schools dominate the bottom of the list even more than charter schools dominate the top. John Oliver should do a segment on how horrible it is that bottom dwelling schools flounder indefinitely without any fear of closure.
