The accelerated development of technology affects all aspects of society, including the education system. The use of information and communications technology has become an integral part of the teaching process. E-learning, as one of many achievements of information and communications technology, offers users many advantages. With its many advantages, but also limitations, it is considered essential for contemporary education. Learning Management Systems (LMS) enable the straightforward administration and implementation of e-courses, adapting them to the end user by creating the conditions for independently managing the progression of learning, teaching, and specialization, as well as, ultimately, (self)assessing. The Loomen online platform is the Croatian version of the Moodle e-learning system, which is frequently a part of preparing education workers for school system reform. The aim of this qualitative-quantitative research was to establish education workers’ satisfaction with the Loomen Moodle platform, along with an evaluation of the system’s usability. The research was conducted on a sample of 86 participants in six primary and three high schools on the island of Brač through an online questionnaire. The research results showed that user satisfaction among education workers who use Loomen can be defined as medium. Based on the research results, it can be concluded that the system is usable to a certain degree and that improvements are needed in order to adapt it to the capabilities and needs of its users.
