About the Team

The Short Term Service (STS) is an innovative, multi-agency pilot at the front door of children’s services, designed to help families earlier, make better decisions faster, and prevent unnecessary escalation into statutory intervention.

Operating as a time-limited, 10-working-day assessment and brief intervention model, STS brings together social care professionals and embedded specialists to rapidly understand risk, need and family context, and take purposeful action.

This is a small, high-impact, multidisciplinary team working alongside the Initial Response Hub/MASH.

Our approach is:

• Child-centred and safeguarding-led
• Evidence-informed and analytically robust
• Multi-agency from day one

Following a time-limited assessment and brief intervention, the team will support clear, confident decisions to:

• Step families down to early help or community support
• Close cases where needs are met
• Escalate appropriately where risks require statutory intervention

STS is a focused, action-oriented service designed to reduce drift, improve family experience, and strengthen decision-making at the earliest point.

This is a 12-month pilot with strong senior sponsorship and real opportunity to shape system change, working at the heart of front-door transformation.
