Call your state's Department of Education to find out the procedures and requirements for certification. It is best to call since, in some states, requirements change frequently and websites and printed materials may be out-of-date. Some states offer free audits of your college transcripts and will tell you what additional coursework you need to fulfill certification requirements.
Confirm that your state is willing to accept coursework from an online or distance-learning institution.
Review any existing college coursework that you have and generate a list of courses that you need to fulfill your state's certification requirements.
Decide if it is best for you to complete the coursework needed for certification or if finding a complete certification program is better. If you already have most of the requirements, it may be best to complete the few courses you need and apply for certification. If you are missing many requirements--for example, if you haven't completed your Bachelor's degree or taken any courses in pedagogy--finding and completing an accredited education program that ends in certification may be more practical.
Search for an online university that offers a teacher licensing program. Check that the license covers the grade and content area that you want to teach. Both bachelor's and master's degree programs are available. Always be sure that the university is accredited.
Contact the program to find out the state in which you will be licensed. With respect to teaching certifications, most states have reciprocity with other states, meaning that licensure in one state will allow you to obtain licensure in your home state.
Contact your local Department of Education to confirm that they have reciprocity with the states in which you will be licensed by the programs that interest you most.
Double check that the courses you plan to take, if you are not completing a certification program, meet your state's requirements for certification.
