The Covid-19 pandemic poses a new challenge in the adoption of ICT in education. The need for educational institutions to develop standards and implement quality assurance in digital education has suddenly gained new significance. The aim of this study is to evaluate the learning experiences of nurse educators in Slovenia acquired during a nine-week modular online course on the design, delivery and evaluation of online study units, based on a quality standard for digital education developed for this purpose. A mixed methods approach was used. The evaluation of the nurse educators’ learning experiences was examined quantitatively (cross-sectional study) and qualitatively (focus group). The Cronbach’s alpha for the entire questionnaire was 0.921, indicating that the internal consistency of the questionnaire developed for evaluation was excellent. The thematic analysis identified three main themes. At the end of the course, the nursing teachers expressed their desire for additional courses in which they could gain and deepen their knowledge of the preparation, implementation, and evaluation of the educational unit with the help of digital technology.
