“Assessment which is explicitly designed to promote learning is the single most powerful tool we have for both raising standards and empowering lifelong learners.”
(Beyond the Black Box, Assessment Reform Group, 1999)

In 2004, a major Assessment for Learning (AfL) project titled the AfL Action Research Project began in 25 primary schools. Supported by CCEA and the Education and Library Boards (ELBs), over the next three years this extended to 65 primary and post-primary schools. The AfL Action Research Project encouraged teachers to experiment with aspects of AfL methodology by adapting the theory and principles of formative assessment to suit their own teaching context, in particular the research of Dylan Wiliam and Paul Black (Inside the Black Box). The emphasis was on building confidence and expertise. Teachers in each ELB had the support of a CASS officer and the opportunity to meet and exchange ideas within learning groups.
