The basic prerequisite for a successful translation is the translator’s exceptionally high level of linguistic competence (in both the source and target languages). Translators have usually acquired these skills from a university or college degree program. Broad-based knowledge in a wide variety of areas, refined intercultural competence and thoroughness in research are also key job requirements. Even before the translation project begins, translators must clarify basic aspects of the project, such as technical terminology, target audience, purpose (for example, a working translation or for publication) and other requirements with the client. Ideally, translators and clients remain in contact throughout the project. Translations into languages that are not the translator’s mother tongue are, of course, checked by expert native-speaking proofreaders.
