A couple of things on your question...
The Portal.. http://vt.portal.airast.org/, has just about everything you will need to get going .
Since your SU did do the assessment last year and I assume you have only upgraded things.. I am not sure how much "testing" you need to do. We had a readiness tool in place for a couple of years and now that function has kind of been absorbed into the portal.
Refer to the specs docs on this page: http://vt.portal.airast.org/resources/?section=technology
to see if your devices meet qualifications.. I would assume yes, based on last year results.

Subject: Preparing for SBAC
Being new to the school IT world this year, I have some SBAC questions for all of you. What do you do to prepare for SBAC's? How do you test your network? Is there a test site to go to in order to verify devices are ready?
Thanks for your help
