How to Hire a Social Worker
Licence and registration checks, where to find social workers, the assessment and case-recording skills to test, a case work sample and red flags.
The short answer
Hiring a Social Worker comes down to verifying holistic assessment of need and risk, using the frameworks your service follows, safeguarding knowledge and confidence in making and following up referrals and clear, factual and timely case recording that separates observation from opinion before you commit interview time. The process below runs 5 stages, screens on evidence rather than résumé claims, and scores every candidate against the same criteria.
- Watch for: Licence or registration that cannot be verified, has lapsed or carries conditions they did not mention
- Watch for: Talks about service users in judgemental or dismissive language
- Score on: Quality of risk analysis in the case study, including what they would check before acting
- Score on: Accuracy and neutrality of the sample case note

Applying for a role like this? Practise the assessment free →When you hire a social worker, the first question is which kind: child and family, adult social care, hospital and medical, school, mental health or clinical therapy roles each need different training, licences and temperament. In the US, licence levels are set by each state board and often tied to an ASWB exam. In the UK, social workers must be registered with the regulator for the nation they practise in. This guide covers where to find social workers, how to check their licence or registration, the skills to assess, a case-based work sample, red flags and onboarding.
Why this role matters
Social workers make decisions that affect people's safety, housing, health and family life, often under time pressure and with incomplete information. They assess risk, coordinate with health, education, police and courts, and write records that may be read in a tribunal or court years later. A good social worker builds trust with people who are wary of services and makes defensible decisions. A poor fit leads to missed risk, weak records and burnout across the team.
Where to find candidates
- NASW (National Association of Social Workers) and its JobLink job board in the US
- Field placement students from CSWE-accredited BSW and MSW programmes, who can join after graduation
- In the UK, BASW (British Association of Social Workers) and specialist sector job boards, checking each candidate on the Social Work England, SSSC, Social Care Wales or NISCC register
- Idealist and other non-profit job boards for community and advocacy roles
- Specialist social care recruitment agencies, for locum cover while you recruit permanently
- Referrals from practice educators, supervisors and partner agencies who have seen the candidate's casework
Skills to look for
Red flags
- Licence or registration that cannot be verified, has lapsed or carries conditions they did not mention
- Talks about service users in judgemental or dismissive language
- Case notes in the work sample that mix opinion with fact or omit who said what
- Cannot describe a time they escalated a safeguarding concern and what happened next
- Treats supervision as a box to tick rather than a place to reflect on decisions
- Claims experience in a specialism, such as child protection or hospital discharge, but cannot describe its processes
The interview process
- 1
Licence or registration check
Confirm the state licence level (for example LMSW or LCSW, names vary by state) on the board's website, or check the UK regulator's public register. Complete the criminal record and safeguarding checks the role requires.
- 2
Practice interview
Ask about a complex case they held: how they assessed risk, who they worked with and what they would do differently. Panels often include a team manager and a senior practitioner.
- 3
Case study work sample
Give a short anonymised referral with conflicting information. Ask for an initial risk analysis, a plan for the first visit and a sample case note. A job simulation of the real assessment and recording work is one option when you have several candidates.
- 4
Service user or partner involvement
Where your organisation does this, include people with lived experience or a partner agency in a short conversation with the candidate. It shows how they talk to people outside the profession.
- 5
References
Speak to a recent supervisor or practice educator about decision-making, recording quality and how they use supervision.

Common questions
What licence does a social worker need?
In the US it depends on the state and the role. Many states have bachelors, masters and clinical levels, often linked to the ASWB Bachelors, Masters or Clinical exam, and clinical therapy roles need the clinical licence. In the UK, social workers must be registered with Social Work England, SSSC, Social Care Wales or NISCC.
Should I hire an LMSW or an LCSW?
Hire an LCSW, or your state's equivalent clinical licence, when the role involves diagnosis or independent therapy. For case management, child welfare or hospital roles, a masters-level licence is often enough. Check your state board's scope of practice rules.
How do I assess a social worker's judgement before hiring?
Use a short anonymised referral and ask for a risk analysis, a plan and a case note, then discuss their reasoning. References from a supervisor who has read their records are the best check on real practice.
Can I use agency or locum social workers?
Locums can cover vacancies, but continuity matters to the people you serve. Use locum cover while you recruit, and check registration and references for locums with the same care as permanent staff.
