Background: This study investigates the social impact of a policy requiring university graduates to pass an English proficiency test by examining the consequences of test use in the workplace in Taiwan. Methods: Interviews were conducted with 19 business people in charge of recruiting potential employees in 17 industries across Taiwan. All these 19 employers hired the graduates from a technological university in southern Taiwan. These interviews sought to discover the importance of English certification as an element of job hunting, the opinions of businesses regarding various certification tests, and their attitudes towards the exit requirement. Results and conclusions: Findings indicate that although these employers were favorably disposed towards this policy, only 13% of them required English certificates as a hiring criterion. Another finding was that 53% of employers regarded the certificates as evidence that applicants who possessed them were diligent and likely to be hard-working employees. These informants interpreted tests differently from testers, focusing on cultural notions of what personal qualities tests highlight rather than on language ability. Due to this and other factors, the impact of the test remained weak.
