This year, my son will make the big transition from elementary school to middle school. The shift is making all of us a little bit nervous. My son is not the most social of sorts, preferring to limit his interactions with children to those who he already knows and with whom he is comfortable. Over the years, I've learned that it's essential to know how to help your child adjust to their new school based on their temperament, corresponding to the environment they're entering. Having changed schools frequently myself, I can tell you it's no easy thing to do.
There are a few things parents can do to help ease their child's transition that are universal regardless of temperament. You can and should tour the school before the first day. This helps your child avoid the awkward search for the bathroom, library, office, cafeteria, and so on. You should also try to speak with the teachers and the administration. It will help you gauge the overall attitude and environment of the school, as well as preparing them for what to expect with your child (particularly important for parents like me whose children have special needs). You can make sure they get the best night's sleep possible, and you can maintain your morning routine as much as possible. All of these will impact how your child transitions to a new school.
Education Corner noted that each child is unique, but that new school anxiety is experienced by every child at some level. How you prepare your child is going to depend on their temperament. I contacted Montessori elementary teacher Deetz Hanna of South Carolina, and she tells Romper that our children are unique — "Some kids transition easily, and for some it takes them a while to feel comfortable. I think consistency and routine are hugely important in establishing comfort. We fear the unknown, or what it feels like we can’t control."
