||In Hong Kong, reading has always been an important component in two of the major public examinations: the Hong Kong Advanced Level (HKAL) Examination and the Hong Kong Certificate of Education (HKCE) Examination. Because of this emphasis in the two examinations, a considerable number of English teachers assign much of their class time to activities related to reading. With regard to reading comprehension and reading tests in particular, this paper attempts to answer the following questions: - How might reading comprehension be accurately measured? - What role does expert judgement play in content validation of a reading test? To answer these questions, a reading test was designed and administered to 62 tertiary ESL students at the Hong Kong University of Science and Technology (HKUST). Nine teachers of English were asked to give their opinions of the test. The scores of the test takers and the views of the English teachers were analysed in detail.
