When we talk about the need for education in academic integrity, the implied recipient of such education is commonly students. This paper argues that to strengthen academic integrity, it is crucial to work with the faculty as well. Since 2014 a unit for pedagogical development at a Swedish university has conducted a project with the aim of enhancing knowledge of academic integrity. In 2014, a survey on academic integrity was sent out and the results were used to develop a new systematic holistic approach with several new measures to promote academic integrity. The aim of these measures regarding faculty was to strengthen faculty members' knowledge on academic integrity, to remind them of their duty to report cases of suspected misconduct, as well as to provide different tools and ideas to improve the academic integrity of their students. The undertaken measures have led to a noticeable increase in reported cases of plagiarism. In 2018, a follow-up survey was sent out. The present paper discusses this systematic approach to promote academic integrity, the measures taken, and the results of the surveys.
