So the 2:1 was in the draft, discussed at the meeting as staying in the IEP, and was deleted from the final version. There definitely needs to be a explanation in the PWN as to why something agreed to was removed from the IEP.
With a case manager leaving their job between having an IEP meeting & getting the final draft to the family, I would hope that the LEA would be the person to do the edits on the IEP so it's someone who was at the meeting.
