Labeling Experience

Cambridge English Certified Speaking Examiner

OtherText

As a certified Cambridge English Speaking Examiner, I systematically assessed spoken English output using standardized rubrics to ensure consistency and quality. I evaluated thousands of candidate responses across multiple language dimensions, providing high-volume, reliable ratings. This experience directly translates to preference labelling and multi-criteria AI output evaluation. • Applied consistent quality judgements to extensive spoken and written output datasets • Conducted regular calibration to minimize drift and maintain inter-rater reliability • Assessed dimensions such as fluency, coherence, lexical range, and grammatical accuracy • Directly relevant to RLHF, evaluation/rating, and annotation QA workflows
