OP also make sure you're not going in there with guns blazing. Remember, you catch more flies with honey than you do vinegar. While I get that you're frustrated, you should really try to remain calm but assertive. Explain why you're there and that you are providing them with all the proof and paperwork they need to release records for your child. If they choose to continue being bumheaded, then politely show them a copy of the state law barring them from withholding the childs records. I would also work to be there at a time when the teacher will be present as well as the principle and any other staff member in their office. Shake hands, introduce yourself etc. That way everyone sees you, knows that you're not a raging loon, and that you are willing to do whatever is necessary to be a strong positive influence in your childs academics and medical care. Remember, BE NICE or you will lose any possibility of positive communication with everyone involved.
