This document outlines different types of assessment used in English language teaching, including informal assessment, formal assessment (testing), and self-assessment. It distinguishes between evaluation, assessment, and testing, and describes first, second, and third generation tests. First generation tests were subjective and focused on grammar, while second generation tests objectively tested discrete points through multiple choice. Third generation tests integrate objective and subjective formats to emulate real-life language use through tasks like role plays or information transfers. The document also discusses principles of testing including reliability versus validity and competence versus performance.
