I'm a first year teacher, and at my district, after the meeting is done and I've checked that all the boxes are filled in, I send the IEP to the district special education office, and someone there reviews it and lets me know if any other edits need to be made (like forgetting to add a date, or I changed the time on one part of the form but not the second part). After those are all completed, then it is finalized and the IEP is officially done.
I don't know if it's the norm, but I will often send the parents the draft at the same time I send it to the special education office, with a note that the finalized version will be mailed to them. Sometimes I'll even print out a draft for them to look at during the meeting that they can then take home with them, if I don't anticipate many changes because I already got input from all the team members prior to the meeting.
