For administrative, communication, instruction and research purposes, RTA uses both Afrikaans and English to conduct its business. Students are entitled to indicate their language of preference and will be assessed in either Afrikaans or English. The RTA, accordingly, requires proficiency in either Afrikaans or English as a prerequisite to admission. Language proficiency includes reading, writing, speaking and listening. Students enrolled for programs with components of a practical nature, supervised practical or field work or Work Integrated Learning (e.g., as employed in the programs for ecclesial office-bearing ministries as pastors), may be required to complete assignments and formative assessment in other languages.

As gesture of our mutual unity, we take care of one another (as far as possible) in a common language. The RTA endorses the development of languages to achieve recognition and standing in academic discourses.
