Teachers of adult literacy and remedial education held about 98,000 jobs in 2004. About 1 in 3 was self-employed. Many additional teachers worked as unpaid volunteers. Many of the jobs are federally funded, with additional funds coming from State and local governments. State and local governments employ the majority of these teachers, who work in adult learning centers, libraries, community colleges, juvenile detention centers, and corrections institutions, among other places. Others work for private educational institutions and for social service organizations, such as job-training or residential care facilities.
