This paper explores the Centre for Insurance, Risk and Data Analytics Studies (CIRDAS) as a case study of online adult education which offers flexible upskilling and reskilling opportunities to employees across the Irish insurance sector. It explores how CIRDAS's agile programme development enabled flexible entry, exit and progression routes for work-based learners. It took an innovative approach to the co-creation of programmes with industry representatives and the granular transversal nature of micro-credentials they offered. The experience of learners is shared to demonstrate the effectiveness of CIRDAS in meeting both employer and learner needs for flexible, stackable work-based learning.
