To be certified to teach in public schools you must meet the state's requirements for the area in which you want to teach. All states recognize the teacher education programs at the undergraduate and graduate levels in their colleges and universities. Teacher education programs include coursework in content areas, methods of teaching and learning theory, as well as student teaching. Once you have completed a teacher education program you can be certified by the state to teach. If you're still in college, you should sign up with your school's career services office.
Many school districts recruit on campus.
Other school districts ask the career services office to send resumes of qualified candidates. Some schools even have online and telephone services that allow school districts to automatically screen applicants by viewing their resume on screen or listening to a profile on the phone. Another way to obtain a teaching position is by simply applying directly to various schools at which you would like to work. If you don't know where to turn, call your city's school district or education department and ask for information and an application. But the most common way college graduates obtain teaching positions is by word of mouth and contacts from their department or college.
