English as a Second Language (ESL) instruction is a critical service provided by the Inner London Education Authority (ILEA). ILEA operates 19 adult education institutions serving 275,000 part-time students in a 12-borough area where 131 different languages are spoken. To provide immigrant adults for whom English is a second language with the linguistic means to participate as fully as they wish in British society, ILEA's Language and Literacy Unit provides a wide variety of classes at all times of day in many locations. Approximately 400 part-time ESL teachers, trained in ILEA inservice programs, provide adult institute classes, off-site classes, linked skills ESL classes combining skills and language training, bilingual employment skills classes, ESL for the unemployed, industrial language training, summer schools, and career awareness. In addition, Further Education colleges combine ESL training with study skills, life skills, and job training. The ILEA program also includes provisions for home tutoring, baby sitting, and student recruitment and referral. Based on a brief evaluation, recommendations include providing a structured curriculum, student assessment and evaluation, professionally developed instructional materials, and extended child care facilities. Appendices include a list of teacher training courses and a description and example of linked skills classes. (SB)
