The aim of this thesis is the design, development and validation of a specific purpose test of English for Taiwanese tour guides (TG Test) on a trial basis. The existing TG test is a general proficiency test, and has a number of drawbacks with reference to the measurement of language use ability as a tour guide at work. The reasons for the use of a specific purpose test is that (1) performance varies according to the language use contexts, (2) a specific purpose test is clearer about the language use domain of interest, i.e., how Taiwanese use English as tour guides in their work, and (3) test performance is interpreted from the perspective of the test user. Central to testing language for specific purposes (LSP) is the notion that test content and test methods are derived from an analysis of a specific language use domain. Task authenticity, directness in test method, and criterion-referencing in terms of interpreting test performance are related to the LSP test design and development. Analysis of language use contexts and the workplace is a critical feature in the LSP test design. Collaboration with field experts is important in LSP test development. Test validation concerns the process of gathering evidence in support of the claim that the test measures the abilities it proposes for a given test purpose. Validity is viewed as a unitary concept (Messick, 1989). Validity inquiry includes collecting evidence of test interpretation, as well as examining the consequences of the test interpretation and test use. Messick's "facets of validity inquiry" will be the framework for the TG test validation. Preliminary results showed that the new TG test was empirically valid and broadly acceptable to the test users.
