The TEF speaking test is conducted through an interview between a candidate and an interviewer-examiner, but the conduct of the latter may represent a possible threat to the reliability of the test. It has been shown that despite many measures taken to minimize variability in the assessment, discrepancies in several aspects may be present among examiners. This study aims to observe whether these discrepancies are found among TEF examiners. A total of 10 participants took part in the research and the thinking aloud technique was used. The results show that discrepancies are present. Examiners may award the same score for the same performance but with varying interpretations, and vice versa. Some may be positively influenced by their familiarity with the candidate’s accent. Others may make irrelevant inferences to make sense of the difficulties faced by candidates. Finally, the interviewer’s attitude when talking to the candidate may be perceived differently and have a negative impact on the score.
