Benchmarks: Phase 2

Trying to hone my benchmarks down to something comprehensive that I can use for assessment, here's what I've come up with so far for 5th grade. It would mean changing my thinking from how students do each week to how they do over a 5 month period, and it's certainly more rigid and less applicable to students' creativity, innovation, and effort. It seems to reduce their work to a set of skills--an idea at which I bristle--but it could still be useful, and it's what my administration is asking for.

The 2nd half of the document includes all of the criteria/understandings that go into each column, which would vary by grade, though most of the column headings could be the same for 3-5 and for k-2. 

The other big question is whether it's doable to assess 750 kids for 14 different elements that have so many sub-elements...

How do you assess students? Do you have a set of benchmarks you use?
