The Slovenian Institute for Adult Education developed the Offering Quality Education to Adults (OQEA) project as an incentive to develop quality in adult education so that we could give advice to different educational organisations regarding self-evaluation of their quality and searching for paths towards further development. 

We started to develop the project in 1999 and the first organisations that educate adults joined us in 2001. In 2011 project Offering Quality Education to Adults celebrated the tenth anniversary of its operation in practice.
