PIMSER strongly recommends the AAAS science assessment for middle school science test questions. Test items are sorted by subject and topic, and each question lists common misconceptions and a breakdown of how hundreds or thousands of students responded to the items. It can be found at assessment.aaas.org
Math Assessment Project
The project is working to design and develop well-engineered assessment tools to support US schools in implementing the Common Core State Standards for Mathematics (CCSSM).
