Generally, the most common practitioners of character education in the United States are school counselors, although there is a growing tendency to include other professionals in schools and the wider community. Depending on the program, the means of implementation may be by teachers and/or any other adults (faculty, bus drivers, cafeteria workers, maintenance staff, etc.); by storytelling, which can be through books and media; or by embedding into the classroom curriculum. There are many theories about means, but no comparative data and no consensus in the industry as to what, if any, approach may be effective.
