Definitely mention the core subjects -math, language arts, science, etc. Have someone help you write the letter, if necessary. Contact OFTP to have comments on it. Show in your correspondence a positive attitude, confidence and successful approach being taken in your program. When school board officials have something to put in a file, they are more content.
School boards get fearful when there is no contact.
If a visit is demanded, arrange for one on neutral ground . Take the initiative. Take along an OFTP representative. Do not let them question your child alone. However, do not volunteer a meeting and do not volunteer information.
