Research has demonstrated links between sociodemographic background and educational achievements in vocational education and training. Student achievements may be additionally impacted by individual characteristics specifically relevant to the domain of the professional training. In the context of professional culinary education, student achievement may be related to their olfactory ability as the human sense of smell is involved in food perception and preparation. However, whether sociodemographic factors and olfactory ability predict educational achievements has not been directly compared in the context of culinary vocational education, which formed the aim of the current study. To identify the strength of these predictors, we measured participants' odor detection threshold, discrimination and identification ability with the "Sniffin' Sticks" test battery and assessed individual significance of olfaction via a self-report survey. In addition to olfactory measures, sociodemographic data (student and parental educational background, financial status) were also analyzed to determine if they predict theoretical and/or practical exam scores. The results demonstrated that a student's educational background was a significant predictor of scores in the theoretical (but not practical) exam. Parental educational background, financial status, and olfactory ability did not predict exam scores.
