This talk will focus on lessons learned teaching the use of QGIS software through various workshops in Slovenia. Workshops must have strait forward learning path with useful results – let’s make a map. The learning process for workshops must follow client organizations requirements and must be tailored to their needs, from basic QGIS skills to using geodatabases with PostGIS and PostgreSQL or to using mobile apps to enhance their own workflow. Workshops are roughly divided into three levels respectively beginner, advanced and professional and enable new users from current level of competence towards a better level of competence. I especially prefer beginners, because they can be taught FOSS4G from the scratch. The users must have an option to ask questions at any time of the course. It is necessary to modify existing courses or add new content to follow the QGIS development and also to follow new open data datasets. Open data are also important part of the teaching and the combination usually intrigue new users to see the added value to their knowledge and work. Teacher must be flexible to answer any question regarding QGIS and open data and the answer ‘I don’t know’ is also good. This means I will give answer later when I will look up the topic. QGIS workshops also give me a chance to give tasks to participants to check their level of knowledge and sometimes give them different perspective on analysis to solve.
