The median annual wage of adult literacy and General Education Development (GED) teachers, also known as adult basic and secondary education and literacy teachers and instructors, was $46,530 in May 2010. The median wage is the wage at which half the workers in an occupation earned more than that amount and half earned less. The lowest 10 percent earned less than $27,090, and the top 10 percent earned more than $83,580.
Classes are held at times when students are not at work, so many teachers work in the mornings and evenings.
