Professional identity involves becoming a particular type of professional through learning, practicing, belonging to professional communities, and developing a digital identity. An individual's professional identity is shaped by their formal qualifications and ongoing professional development as well as experiences like collaborations, research, engaging with communities of practice, and using evidence-based practices. Professional portfolios can be used to document an individual's professional identity by collecting information on their knowledge, values, skills, influences, learning experiences, goals, and participation in professional networks.
