Sentence repetition testing (SRT) is a methodology for investigating patterns of community-wide bilingualism. It is a screening device for testing for bilingualism in an entire community, and it is a valid test for second-language proficiency. High correlations have been found between the performance of second-language speakers on SRTs and descriptive estimations of second-language proficiency. These two methodologies give promise of being reliable in the assessment of language proficiency in low literacy rate contexts.
