Over the course of the project, a series of various tools have been utilised to support project partners in self-assessing 21st-century skills in non-formal science learning, and credentialisation of such learning. The tools were implemented from June 2019 to January 2021 and used by approximately 1200 learners, helping us to understand how 21st-century skills are used in non-formal and informal science learning by making these skills explicit to the learners.

From self-assessment tools focussing on the four core 21st-century skills (creativity, collaboration, communication, critical thinking), to the credentialisation tool, which was a digital badge and paper certificate, both created with the Open Badges specification, this document outlines these tools and their implementation within the SySTEM 2020 “testbed education programmes”—non-formal science learning programmes in eight practice partner locations.
