Abstract: This study examined the validity of the reading section of the English for Specific Purposes (ESP) test, the Test of English for Thai Engineers and Technologists (TETET), using the Rasch model in relation to Messick's (1989, 1995) six aspects of validity. Data were collected from 179 participants at a science and technology university in Bangkok, Thailand, and analyzed with WINSTEPS Rasch software version 5.4.1. The results indicated that the reading section generally met Messick's criteria, with strong evidence for content, substantive, and structural validity, and preliminary evidence for external, generalizability, and consequential validity. To distinguish it from general English tests, some items, particularly in the survival and internet reading sections, required revision to enhance content (representativeness and technical quality), and substantive aspects. These findings not only provide practical guidance for refining TETET and similar ESP assessments, but also highlight both the strengths and the limits of Rasch analysis in addressing a comprehensive validity framework. Future research should therefore complement psychometric findings with qualitative evidence to build a more complete validity argument. [ABSTRACT FROM AUTHOR]
