Massive open online courses (MOOCs) have emerged in informative and scientific literature as a revolution with great potential within the educational and training world. However, at the same time, there are discrepancies and questions about the pedagogical value and scope that this movement has on higher education. Therefore, the MOOC universe is the object of educational consideration among various authors and institutions in the globalised world, but some dimensions and implications of their evaluation still need to be assessed and analysed from different perspectives.

In this paper, we introduce a comparative overview of the quality indicators of two instruments for assessing MOOCs: Standard UNE 66181:2012 on quality management for virtual teaching, and the training analysis instrument for teaching models and strategies of online university courses (ADECUR). Lastly, we will introduce the development of a tool for assessing the quality of MOOCs based on the strengths of the two instruments examined.
