This thesis deals with a translation of three texts from Croatian language into English. The first source text talks about art history and museology and it is taken from an exhibition catalogue written by a curator and the exhibition author from City Museum of Rijeka. The second text is focused on education, precisely, the impact of project-based teaching on the attitude change among students towards the teaching plan in biology. The third and the final text deals with shipbuilding and engineering and it is an excerpt from a textbook about the technology of the construction of ship hull. After every translation of the text there is a detailed analysis and a commentary introducing some difficulties and stumbling blocks that had arisen in the process of translation. The main part of the translation, workflow, is the Genre Analysis from which I used 11 points that I found most important – genre, source, audience, purpose of writing, authenticity, style, level of formality, layout, content, cohesion and the terminology of the subject. The final part of the thesis consists of a conclusion that summarizes fundamental characteristics and problems of the translation process and the knowledge that a translator has to have in order to face these challenges.
