Introduction: The most critical intervention to control SARS-CoV-2 infection requires appropriate knowledge and attitude towards the virus. Objective: To determine the level of knowledge, attitudes and practices of students of a health services' vocational school with regard to COVID-19. Methods: Cross-sectional study carried out between May and June 2020 in a university of the Turkish region. Data were collected through an online survey portal. Results: Four hundred and fifty-four questionnaires were completed and returned. Students of medical laboratory techniques and first aid and emergency medicine had significantly higher knowledge scores (p < 0.001). More than 43 % of the students (n = 201) used the TV as their main source of information on COVID-19. There was a positive attitude towards preventive measures such as avoiding crowded places and maintaining hand hygiene and social distance. Conclusions: Health services vocational school students have good knowledge and positive attitude towards COVID-19. The main sources of information were the TV and social media. For this reason, more attention should be given to these issues in the curriculum in order for science-based information sources to be used.
