Here's a resource that I found really helpful because it has a lot of ideas for assessing students. It's "Authentic Assessment: Getting Started" by Connie Greenleaf.

Sorry that I can't get you more at the moment. I have to go do a teacher observation in ten minutes.
Let me know what you think of the resource.
