Material available from SBAC web site
I am waiting, like many of us, for the release of the final Mathematics Content Specifications from the Smarter Balanced Assessment Consortium. If you haven't reviewed the draft specifications, click here. In the meantime, I thought I would point out some of the other materials available at the Consortium's Web site (http://www.k12.wa.us/smarter/).
The Consortium recently began development of the Mathematics Item Specifications. This document, alongside the content specifications, will provide valuable information about the future SBAC tests. The Consortium released draft portions of the specifications from the first two "Showcases," including sample items. I think these documents will give you an early look into how items for the SBAC assessments will be designed.
