To begin a career in special education, you first must decide on a focus of study. The two main categories of special education are teaching and support services. To become a special education teacher, you must earn a bachelor's degree, along with a teaching certificate in special education. Once you have your degree, you must complete continuing education courses throughout your career to stay up to date. For support services, you may be required to earn a master's degree and must also seek out continuing education regularly.
