You need to be licensed to teach in public schools. All states require you to have at least a bachelor's degree and a certain amount of supervised practice teaching experience. Some states also require that you have a master's degree.

Part of the licensure requirements of many states includes one or more tests such as the Praxis exams. Passing these exams helps show your competency to teach. You will likely take the Praxis II subject assessment in elementary education. You may also take the Praxis III, which tests your knowledge of general education theories and teaching methodology.

Getting a bachelor's degree prepares you to teach at the K-12 level. If you want to teach adults in a community college, or if you want to teach at the university level, you need to earn at least a master's degree as well.

Some programs offer part-time study options so that you can continue to work while you're in school.

Students use computers to learn and evaluate educational software programs and to develop customized training to meet the needs of students with special needs.
