Cambridge English for Schools offers: - an approach centred around the whole educational context of learning English at school - links across the school curriculum to other subject areas throughout the course, and to other classes in different countries - content and concepts related to learners' ages and levels of ability - an organisation which takes into account the realities of teaching English at school: mixed abilities, mixed motivation, time available, and class size - material which has been developed and successfully piloted in collaboration with teachers and classes in many parts of the world. The course consists of four levels, plus a Starter level for learners with little or no previous English. Level 1 assumes that learners will be familiar with a range of basic vocabulary and grammar, although this is revised and evaluated thoroughly in the opening units.
