STEM is the acronym of Science, Technology, Engineering, and Mathematics fields. STEM education refers both to teaching and learning in the above-mentioned disciplines, but especially to teaching and learning a new discipline based on the integration of Science, Technology, Engineering, and Mathematics. The present survey aims to investigate the opinion of a sample of 110 respondents, students from Romanian universities, taking into account: a) their experience in STEM fields during high school studies; (b) the engineer's profession and the engineer's skills; c) the factors that influenced their option to study one of the STEM fields. The results show that the respondents have been interested in STEM fields since secondary and high school; this interest determined them to choose to continue their studies in a STEM field. Also, the majority of respondents agreed that the choice of their university specialisation was influenced by the teachers who taught them the subjects that they study at the university during their school years. The data also show that the students are convinced of the importance of the engineer's profession as well as of the engineering knowledge and skills.
