Leveraging Self-Sovereign Identity for Certifying Extra-Curricular Competencies and Skills in University Programs

Traditional academic degrees often fail to capture the full range of competencies students acquire throughout their university education, particularly those developed through laboratory activities, internships, volunteering, and other extra-curricular experiences. This limitation hinders students’ ability to differentiate themselves in increasingly competitive labor markets and complicates employers’ identification of candidates with balanced technical and transversal competencies. To address this challenge, this paper presents a design-oriented research study proposing a Self-Sovereign Identity (SSI)-based framework for the decentralized issuance and verification of academic micro-credentials. The proposed approach combines a structured methodology for generating micro-credentials with a decentralized architecture supported by a prototype implementation based on SSI technologies. The framework enables universities, lecturers, and other trusted entities to issue verifiable and tamper-resistant credentials that students can securely manage, control, and share through SSI wallets. Unlike existing approaches, which typically focus either on secure credential infrastructures or on the pedagogical value of micro-credentials, the proposed framework integrates both technological and educational perspectives while explicitly supporting the certification of extra-curricular and soft skills. The system supports the creation of granular and portable competency profiles while enhancing transparency, authenticity, interoperability, and trust in credential management. Furthermore, the paper discusses key challenges associated with large-scale adoption, including trust management, governance, scalability, interoperability, and issuer credibility. The results suggest that SSI-based micro-credentialing represents a promising approach for improving the recognition of both technical and transversal competencies, contributing to better alignment between higher education outcomes and evolving labor market demands.
