Go to your local social services, welfare or employment office and ask for information about state- or federal courses for speakers of English as a second language or for native adult speakers who need improved literacy skills. ESL or adult language skills courses may involve online coursework, one-on-one tutoring or group classes.
Check out churches and local nonprofit agencies that offer human services assistance, and inquire about English language learning programs offered free to the public. In addition, visit your local library and ask about free courses sponsored by library patrons or offered via partnerships with local schools or nonprofit organizations.
Check out English language learning websites that allow you to study English free at your own pace, such as the U.S. Department of Education’s U.S.A. Learns website, the BBC Learning website and the Englishlink site.
