The type of school that you would like your child to attend is also extremely important. For example, many private schools have a focus on a particular religion. Other private schools have a focus on a specific gender, such as an all boys school or an all girls school. If you would like your child to be able to better understand and appreciate your religion, a private school with a religious focus may be your best bet, and so on.
One of the many reasons why parents send their children to private schools is because of the student teacher ratio. In private schools, you will often find that the class sizes are smaller, but it isn't always guaranteed. If you want your child to be able to have a close relationship or a one-on-one relationship with his or her teacher, you will want to closely examine the student teacher ratio of your local private schools.
