This study aims to investigate test takers' strategies for the reading section of the Test of English for Thai Engineers and Technologists, or TETET, which is an innovative computer-based English for Specific Purposes (ESP) proficiency test. Five fourthyear undergraduate students who obtained overall high scores, particularly in the reading section, were selected to participate in the study. A stimulated recall interview and the reading section of the TETET were used as the two main instruments. The strategy rubric by Cohen and Upton (2006) was adopted in order to analyse the data. The results revealed that test management strategies were the most frequently used strategy type across all sub- sections of the TETET reading section, while test-wiseness strategies were the least frequently used strategy type. In addition, there was concordance between the types of strategies used and the item types in the sub-sections. These results provide evidential base for the construct validity of the TETET reading section and can be used as insights for further test development and revision.
