This presentation explores the uptake, impact and use of the Clilstore authoring tool and open access repository of ready-made educational resources for content and language integrated learning. The system has been undergoing constant development since its inception during the “TOOLS for CLIL Teachers” project and is currently undergoing extensive improvements by virtue of the “CLIL Open Online Learning” project. Both projects were co-funded by the European Commission. The analysis is based on the data obtained from a survey administered to registered users. A cross-section of educational practitioners who had registered with Clilstore was invited to provide feedback on a range of factors relating to the platform's functionality and the impact it had made to their professional practice. There were 61 responses with a sectoral breakdown of Secondary = 36%; HE = 28%; FE = 27%; Other (Primary, Community) = 9%. The authors will discuss the findings according to five broad categories: uptake, exploitation, uniqueness, innovation, and awareness. To conclude they will illustrate the system and highlight its potential benefits for both autonomous and guided learning.
