The simple answer is in most states, yes. It is assumed that parents have access to all materials regarding their children's education. Most states indicate that the parents are more than within their parental rights to ask for the meeting to be recorded, a copy of all documents discussed during the meeting and the minutes of the meeting. Before each meeting you should receive a copy of parental rights. Please peruse them and don't feel compelled to sign any form regarding your child's education at the meeting except for a record of attendance. Take time to review any and all information proposed.
