IEP Development -2nd Week Assignment for School Law

This assignment required me to dig deeper into IDEA and into the process of planning an IEP.  I have a better appreciation for the diagnostician at my school.  She mentioned that her number one job requirement is to stay current on Special Education laws.  Just reading the laws for this assignment is a little overwhelming.  I couldn't imagine being responsible in making sure all the teachers in the building and parents of special education students are current on the laws.   

EDLD 5344- School Law

I'm taking my 3rd master's class (in Administration).  There are many things to learn.  I have heard of Section 504 and IDEA (now IDEIA), but didn't know that there have been ammendments to them. And  this is my 6th year to teach.  Where is the lack of communication coming from?  If I'm required to follow the laws (IEPs are a legal document), shouldn't it be a requirement to let teachers know when something has changed?  I'm feeling a little frustrated at this point.
