This document summarizes the implementation of a competence-based blended learning program at the Dutch Tax and Customs Organization. The goals were to train employees efficiently and keep their skills up to date. A blended model was designed using e-learning, self-study, group meetings, tasks and assessments. Teachers and students found the active learning approach engaging but time-consuming to implement. Initial results showed customized learning paths and modular curricula were effective. Refinements were needed around author support, teacher training and communication.
