The bottom line on charter school studies

Don't believe the hype, regardless of what you think the hype is. Kevin Welner of the National Education Policy Center and CU-Boulder ( says that the CREDO studies essentially find no difference in charter and traditional public schools as measured with student outcomes. Also, the CREDO studies suffer from a few methodological issues that should dissuade us from believing they are the definitive word in charter school research. (Also, I like this post because Kevin mentions hierarchical linear modeling and, just for a moment, I wanted to think that all the readers would know what that was. Given that I don't really know much about HLM, that fantasy faded quickly.)
