Continuous Auditing (CA) is a methodology for issuing audit reports simultaneously with, or a short period of time after, the data is entered into the information system. The possibilities and challenges of CA have been researched previously. However, limited studies focus on the practical application of CA maturity models. In this study, we bridge this gap by developing a maturity model, including measurements to evaluate the current state of an organizations’ CA. To accomplish this goal, we adopted a focus group approach to create the maturity model in multiple iterations. During these iterations, the model was developed in concurrence with three pension funds, one accountancy firm, one mortgagor and two consultancy firms for the pension market. This resulted in a maturity model, which consists out of five maturity levels and four capabilities. The maturity levels are: 1) initial approach, 2) ad hoc approach, 3) defined approach, 4) managed approach, and 5) optimized approach. The four capabilities are: A) systems, B) data, C) organization, and D) people.
