Abstract: Test fairness is one of the overriding concerns in language test research and development. And how teachers conceive and implement test fairness is of critical importance in ensuring test fairness. This paper, by means of a questionnaire survey, looks into the perception and practice of teachers with regard to test fairness. The results show that teachers were aware of test fairness in some aspects and had practiced accordingly, while in other aspects teachers were not clear and thus failed to adopt adequate measures. Finally, the paper proposes that proper training be provided to teachers so as to raise their awareness.
