The document introduces 5 test-beds for the ROLE project, each focusing on transitions across different learning contexts. The test-beds have diverse user bases like employees, students, and lifelong learners, and purposes such as continuing education and transitions between jobs or university and work. Common goals across the test-beds are to take more learner-centric approaches, increase openness and responsiveness of learning environments, enable collaborative learning, and help with transitions across different stages of learning.
