Transition from school to ...?

Transition services are an important part of IEPs for students who have disabilities and are 16 years of age and older. The word transition is defined by Webster's as " a passing from one condition, place, etc.  to another".  With this definition in mind, I am puzzled as to why this "passing" seems to be a one sided issue.  The school district is responsible for transition planning with the student on post secondary goals and is required to provide transition services that help the students to reach for these goals.  The problem with this is that rarely are there representatives from community agencies available during the transition pre- planning meetings nor do they usually attend the actual IEP meetings for these students. Where is the receiving side to this issue?  Our focus as teachers is to prepare these students to be as independent as possible and to become productive/active members in society. We are helping them to explore their post secondary options but we as teachers need the input from the actual agencies that will be serving these students when they leave the school system at 22. It seems to me that there needs to be a step in between schools and the communtiy. Maybe an interagency collaboration team that can truely represent the bussinesses, schools and programs that these students will be participating with in their communities. Where is the coordination between school and the community agencies? We seem to be dropping the baton at the handoff of these students during the "race" called transition.
