This link is to a statement from the president of the National Council of Teacher of Mathematics on Common Core State Standards and how they will be assessed. http://www.nctm.org/about/content.aspx?id=30169
This is a link to the conference report by the Joint Task Force on the Common Core Standards that is referenced in the article. http://www.mathismore.net/resources/MovingForward/MFT_Final_Report.pdf
In my opinion, some of the key recommendations in the report:
Recommendation 1.: Ensure the standards for mathematical practice are embedded within the assessments.
Recommendation 5.: Utilize research based strategies to investigate approaches to assessment item development.
Recommendation 6.: Support long term sustainability of assessments and an evidence based approach to appropriate revisions of the assessments.
Recommendation 9.: Develop and apply a means of accurately describing curricular emphasis and alignment in existing curricular/instructional materials with regard to the standards for mathematical practice and the content standards. Engage the full range of curriculum developers in alignment discussions, and if materials are not
well aligned, revise them.
Recommendation 16.: Request and lobby for policy level changes to slow the timeline and process of implementing the assessments, given the complexity of the task.
Overall, the report from the Joint Task Force seems carefully thought out and the suggestions are ones that would help to make positive changes. Here's hoping that is the case.
