REVIEW OF LITERATURE
The literature in the fields of reading research and reading assessment research is vast and complex. In the following section, we review briefly those areas thought to have particular relevance to the current study. These include the idea of construct validity; theoretical models of reading; and inventories of reading skills and strategies. We begin with a brief review of the IELTS Academic Reading Test, including an account some of the changes that have been made to the test over the 20 years of its use.
