Mandatory reporting of child abuse and neglect is a complex yet essential responsibility tasked to many professional groups working with children, including the early childhood education and care (ECEC) workforce. This paper provides a narrative review synthesising the empirical literature on factors influencing ECEC educators' reporting of child abuse and neglect, including knowledge and training, attitudes, thresholds for reporting, work experience and context, inter-organisational co-operation and self-efficacy. These factors can act as barriers and facilitators to effective reporting practice and are likely to interact in dynamic yet modifiable ways. Findings from the review may be useful for informing future education and training initiatives for the ECEC workforce. Further research is warranted in this area.
