The provision of English language learning for those with other first languages who have settled in the UK. The Adult ESOL Core Curriculum of 2001 outlines the skills, knowledge, and understanding that non‐native English speakers need to demonstrate as set out in the National Standards drawn up by the Basic Skills Agency. The adult ESOL curriculum, which relates to Adult Literacy Standards and English as a Foreign Language, separates the skills of speaking and listening, to reflect the tendency for ESOL students to understand more than they can speak. ESOL learners constitute a diverse group of students in terms of the disparity in their cultural, educational, linguistic, and economic backgrounds. ESOL practitioners are therefore required to meet the challenge of planning and delivering differentiated but inclusive teaching and learning sessions. Teachers of ESOL have, since 2004, been required to gain specialized practitioner qualifications at level 4 on the National Qualifications Framework. See also basic skills.
