Early-career midwife attrition (30–67%) threatens maternity care, well-being, and workforce stability. The three-year METIS project supports sustainable transition-into-practice through Eportfolio-based interventions. It enhances job application skills (WP2), facilitates employment transition (WP3), and trains mentors in Eportfolio use for career guidance (WP2-3). These efforts aim to improve maternity care, workforce retention, and alignment with EU regulations (WP4).
