The skill sets required for the successful completion of projects have changed dramatically in recent years. Employers now expect project practitioners to possess a balanced mixture of soft and technical skills. The use of group-based assessments in higher education institutions (HEIs) is becoming increasingly important to develop the demanded project management competencies. This study aims to identify best practices for designing and administering group-based assessments through a systematic literature review (SLR) followed by interviews and focus groups. A database search is conducted, inspired by the guidelines of the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses). The research is in work-in-progress. It is expected that the higher education sector will benefit from the outcomes of this research as the identified best practices will guide academics to design group-based assessments rigorously and systematically.
