From STA: 

"Teaching at a private school can be tremendously rewarding work.  Small classes of college-bound students help create a fertile teaching environment where teachers can make a powerful difference in the lives of students.

Southern Teachers can help new teachers get one of these great jobs.  We work with almost 600 private schools around the South, and they list thousands of jobs with us each year.

In order to place candidates in appropriate positions—jobs where they have the potential to be successful and impactful—we interview every candidate and speak with their references.  Understanding what a candidate can do and wants to do helps us pursue the most suitable opportunities for them.

Candidates should proceed to our website to begin an application.
