Global CoVEs initiative bases its intervention on SAT the Self-Assessment Tool, designed to produce and manage evidence necessary for the continuous improvement of Skillman CoVEs. SAT is a quality control and development tool implemented alongside all the CoVEs activities and for further use, to improve the excellence level of each CoVE and of the platform, targeting the progresses indicated in the Maturity model for CoVE development and grouping the performances under the three clusters of Teaching and learning, Cooperation and partnerships and Governance and financing/funding.
