The most common scenario is for a principal to work with the teachers and guidance counselors to create classrooms that are balanced in all ways, including boys/girls, slow/fast learners, special needs, and so on.
In which type of learning environment does your child excel? Sharing this information with your child's school can help him adjust in those first days. For instance, does your child stay on task, or does he need strong guidelines? Does he tend to make friends easily, or is he withdrawn?
Above all, be careful about listening to gossip about a particular teacher. Your child's learning needs should be what matter, not what a neighbor has to say about a teacher with a strict reputation.
