The SEALLL project focused on self-evaluation in lifelong learning, allowing participating adult learners to expand their learning horizons through considering the perspectives of others whilst retaining overall control of the learning process. Activities centred round the development of a modular framework of quality assurance dimensions, indicators and criteria, supporting self-evaluation in lifelong learning and enabling users to design their own evaluation process. In addition to the developed SEALLL self-evaluation tools, a Grundtvig In-Service Training (IST) course was developed alongside a manual for teachers and trainers, each providing techniques for the introduction and implementation of self-evaluation in adult learning.
