Although anyone CAN take any Praxis Exam, the primary purpose of Praxis Exams is to demonstrate mastery of your subject for the teacher certification process.
The Praxis Exam can help you land a job (or at least earn an interview) at a school which hires at least some teachers without certification. For example, I see you are from Roanoke Rapids -- there is a good charter school there (KIPP Gaston) which might well consider an unlicensed teacher who had earned an impressive Praxis School.
john recommends the following next steps:
- If your question is really "How do I get a teaching job without certification?" explore both charter schools and private schools.
- Before you take a Praxis exam, make sure you purchase and use a study guide.
