This course prepares fundamental principles and best practice of testing and assessment for English language teachers at the undergraduate level. It considers a range of concepts and skills of assessing learners’ English language proficiency. Issues such as testing methods, testing techniques, and evaluation measures are brought into class discussions and analyses. Students are required to work on different types of testing for different skills, including pronunciation, grammar, vocabulary, and the four macro language skills. A critical perspective on common testing methods and procedures is employed for the exploration of their limitations on validity and washback effects.
