There is no college or graduate level program in this region specifically designed to train adult basic education teachers. The obvious answer is by working in the field over a period of time. You can get experience by volunteering as a tutor or in some other capacity at a program. You might initially get a small part-time job through which you can gain the experience that will be helpful in going for other positions. In general, no.
Different programs have different priorities in their hiring.
In some settings, such as workplace education, pay may be higher, while in other settings, such as at community-based organizations, the pay scales may be lower. A few programs provide life insurance and retirement benefits. Classes for adults are held mornings, afternoons, and evenings, depending upon the program. Therefore the number of hours and work schedule will vary from job to job. Some teachers might work during the day, or only evenings, and some might work a combination of day and evening hours.
