With the growing diversity of professions working in schools, interdisciplinary partnership and collaboration are growing quickly the world over. Apart from traditional teaching and learning concerns, awareness of children and youth mental health issues and socio-emotional wellbeing, grew readily since the 2000s. Rising in tandem with this trend is the number of psychologists, social workers, and counselors joining educators to support children and young persons in schools. Challenges such as misconception of roles, differing perceptions as well as cross-disciplinary misunderstanding threaten to prevent concerned professionals in working collaborative to help children and young persons in need. Fortunately, this aspect of interdisciplinary partnership in schools gains the much-needed attention in research from Asia and the Middle East to Europe and the Americas. Models and frameworks suggesting best practices for interdisciplinary collaboration emerged in school psychology, counseling and social work literature. Also growing in tandem is research in methods of measurement and evaluation of such collaboration as well as studies on pre-service professional training on interdisciplinary collaborative skills in the related disciplines.
