Although online education is a paramount pillar of formal, non-formal and informal learning, institutions may still be reluctant to wager for a fully online educational model. As such, there is still a reliance on face-to-face assessment, since online alternatives do not have the deserved expected social recognition and reliability. Thus, the creation of an e-assessment system that will be able to provide effective proof of student identity, authorship within the integration of selected technologies in current learning activities in a scalable and cost efficient manner would be very advantageous. The TeSLA project provides to educational institutions, an adaptive trust e-assessment system for assuring e-assessment processes in online and blended environments. It will support both continuous and final assessment to improve the trust level across students, teachers and institutions. The system will be developed taking into account quality assurance agencies in education, privacy and ethical issues and educational and technological requirements throughout Europe. It will follow the interoperability standards for integration into different learning environment systems providing a scalable and adaptive solution. The TeSLA system will be developed to reduce the current restrictions of time and physical space in teaching and learning, which opens up new opportunities for learners with physical or mental disabilities as well as respecting social and cultural differences. Given the innovative action of the project, the current gap in e-assessment and the growing number of institutions interested in offering online education, the project will conduct large scale pilots to evaluate and assure the reliability of the TeSLA system. By the nature of the product, dissemination will be performed across schools, higher education institutions and vocational training centres. A free version will be distributed, although a commercial-premium version will be launched on the market.
