Rereading this, I gave information that is confusing. And an annual review and a reevaluation are not technically one and the same.
The re-evaluation is required every 3 years. It can be done annually if the parent or the sd requests it.
The "informal means" I was referring to are the present levels of performance (e.g., often "grades" which means zero to me) and teacher check sheets.
Whether a new IEP or the annual review, all IEPs have the same content requirements. http://www.wrightslaw.com/bks/feta2/ch12.ieps.pdf and https://web.archive.org/web/20080512052619/http://a257.g.akamaitech.net/7/257/2422/01jan20061800/edocket.access.gpo.gov/2006/pdf/06-6656.pdf may be good resources for you.
I just really never can figure out how one is suppose to write effective IEPs if there's no objective means of measuring progress.
