Social workers are among the largest group of professionals in the mental health workforce and play a key role in the assessment of mental health, addictions and suicide. Most social workers provide services to individuals with mental health concerns, yet there are gaps in research on social work education and training programmes. The objective of this scoping review is to examine literature on social work education and training in mental health, addictions and suicide.Using a scoping review framework developed by Arksey and O'Malley, we will search for literature through seven academic databases: PsycINFO, Sociological Abstracts, CINAHL Plus, Social Sciences Abstracts, Education Source, ERIC and Social Work Abstracts. Two independent reviewers will screen articles utilising a two-stage process. Titles and abstracts will be reviewed in the first stage and full texts will be reviewed in the second stage. Selected articles that meet inclusion criteria will be charted to extract key themes and they will be analysed using a qualitative thematic analysis approach.This review will fill a knowledge gap in social work education and training in mental health, addictions and suicide. Ethics approval is not required for this scoping review. Through dissemination in publications and relevant conferences, the results may guide future research and education in social work.
