Diane Ravitch is a prolific blogger. She posts frequently and includes lots of links to media outlets or other blogs. I can't keep up with her and don't always agree with her, but her blog does serve as a nice repository of education policy being considered across the country.
In a recent blog post she does a quick analysis of the most recent NAEP report. If her analysis is correct, the last 5 years have not been good for our nation's children. Here in our district, we've made significant achievement gains in the past 5 years. I know others have as well.
