Apprentices pass the professional practice during their occupational preparation, which comprises active involvement into the working process. From the point of view of health protection of the youth and complying to work safety, it is important to create the working conditions, which respect their body parameters. Upon this reason, anthropometric measurements were carried on at secondary vocational schools in Banská Bystrica and Kysucké Nové Mesto. Altogether, 295 apprentices aged 15-20 years were measured. Results gained from 17 years old apprentices were compared to the results of measurements of the same parameters in 17 years old students of grammar schools. Drawn upon our results, we can point out to the fact that it is suitable to use body parameters of future users for the purpose of arrangement and assessment of working places and classrooms for apprentices.
