If you have a concern, start with the teacher privately. This gives her a chance to explain what really happened, which takes care of most problems. This has happened to me many times, such as the time a parent thought I favored abortion because I challenged her child to show me in Scripture why it is wrong. A simple discussion solved the misunderstanding. If you can t resolve the problem with the teacher, ask about the proper steps to follow.
Most schools have a formal procedure to handle disagreements.
Your interest in following their plan protects your reputation as a parent. Respect the teacher. Be careful to not go around, behind or over the teacher. Pray for the teacher. If you multiply your needs as a parent times the teacher s 25 students, you will feel the need to pray for her.
