Aim: This article aims to present a study protocol that represents a tool developed for a learning needs assessment. With a pilot study, based on the presented concept of a model study, we will be able to assess what mental health learning content is not yet part of formal higher education for professionals working in community mental health centres, but has been identified as necessary for inclusion. The presented tool is transferable with appropriate modifications. The goal is to conduct multiple research with the same basic tool at all levels of the educational system and in continuing professional education for all professionals who work with people. Methods: The learning needs assessment study protocol presented uses both quantitative and qualitative research approaches. It is expected that the research will be conducted in several interrelated phases that holistically cover the needs assessment process. Results: The pilot study will provide insight into the advantages and disadvantages of the prepared learning needs assessment tool. Through the research study, the learning needs of professionals working in community mental health centres, will be identified. Conclusion: Professional mental health care workers must be equipped with the necessary knowledge, skills, attitudes, and values to perform their work with quality. By implementing appropriate mental health learning content in educational processes from pre-school education to higher education and further to continuing professional education, we can impact the mental health of the entire population. Since this can lead to acquiring the competencies necessary to care of one’s own mental health and that of others, it can be considered an important public health intervention.
