You need to finish a “state-approved teacher education programs including a student teaching or intern experience.” There are a few on-line colleges where this can be done. After completing the course work you will have to student teach for a semester (sorry no getting around that). Somewhere during this time you will have to complete your Praxis Testing and start your application. There are new regulations for certification: you must have: a 3.0 GPA and academic preparation in math and English. Check at the PA Department of Education website for more information. Good luck!
