I like tos end out parent/teacher conference reminders. I have included on this form a section for parents to return saying whether they can or cannot make the conference time. I can then follow up to reschedule the conference. This insures all parents can make it to a conference. At the bottom of the return form is a place for parents to write specific concerns, or items they would like to discuss at the conference. I find this helpful in giving me a 'heads up' so that I can gather data before a conference, rather than being caught off guard in the middle of a conference.
