The document discusses evaluation in ESP (English for Specific Purposes) courses. It addresses four main questions: 1) What should be evaluated? 2) How can ESP courses be evaluated? 3) Who should be involved in the evaluation? 4) When should evaluation take place? There are two main types of evaluation in ESP - learner assessment and course evaluation. Learner assessment is important for determining what language skills students already have and what additional instruction they require. Course evaluation helps to assess whether the course is achieving its intended objectives. Key aspects of evaluation include placement tests, achievement tests, questionnaires, discussions, and interviews.
