Most counselors are required to have a master's degree in counseling. Graduate level counseling courses are usually given by the department of education or psychology. During graduate school, counselors take classes and learn to work with clients. An experienced counselor supervises the work done with clients. Some colleges recommend that students who are interested in school counseling first obtain teaching certificates and classroom experience before entering a counseling program.
Volunteer work is a good way to get experience working with people in various counseling settings.
The Indiana Professional Standards Board is the state agency responsible for the licensing of school counselors in the state of Indiana. All states require that school counselors be certified to work in school counseling. Requirements vary by state.
