This study draws upon findings from a cross-sectional survey of 278 social work students enrolled at one of six universities across Ireland. Multivariate multiple regression was used to examine the effects of being a past or current user of social work services, or a past or current unpaid carer, on their motivation to become a social worker. Most respondents were 23–30 years old and female. Wanting to help people and overcoming oppression were the main motivators to engage in professional training. Half identified as past or current unpaid carers, which significantly predicted motivation to become a social worker. Less than a third reported previous/current social work support due to witnessing domestic abuse, or the consequences of mental ill health or addiction as a child or adolescent. Others disclosed firsthand experiences of poverty, mental illness, addiction, bereavement or custody battles with ex-partners. Being a past or current service user significantly predicted motivation to become a social worker. The discussion suggests that universities explore ways to improve support for care experienced students or student carers to prevent withdrawals. Examples include a more robust and accessible mental health service, increased financial support, flexible approaches to assessment and meeting the requirements of placements.
