The Single Central Record for supply teachers: what agencies must track

The Single Central Record is the document every Ofsted inspection and local authority audit goes to first. For a school with a stable staff list, keeping it current is a manageable, if tedious, administrative task. For a school working with an education supply agency and a rotating pool of supply teachers and TAs, it becomes considerably harder, and that is exactly where most gaps get found. This guide sets out what the SCR actually is, where the boundary between agency and school responsibility sits, and how to keep the record current when your candidate pool never stops moving.

What the SCR actually is

The Single Central Record is a single document (in practice, usually a spreadsheet or a system export) that lists every person working in a school, including supply staff, volunteers, governors and contractors with regular unsupervised access to children, alongside evidence that the required pre-appointment checks have been carried out. It is not a policy document. It is a record of fact: this specific check, on this specific date, with this specific reference number.

For supply staff, the SCR entry is only as good as the information the placing agency provides. A school cannot verify a DBS certificate it has never seen the details of, and it cannot record a check date it was never told. This is the structural reason so many SCR gaps trace back to agency-placed staff rather than directly employed staff, the information has to cross an organisational boundary before it can be recorded, and every handover is a point where detail can get lost or simplified.

Agency responsibilities vs school responsibilities

This is where confusion creates real risk. The school is accountable for its own SCR and for satisfying itself that appropriate checks are in place before a supply worker starts. The agency is responsible for actually carrying out those checks on the candidates it represents and for being able to evidence them clearly and quickly. Neither party can fully discharge the other's obligation, which is precisely why both sides need their own clean records rather than each assuming the other has it covered.

In practice this means an agency should be able to hand a school, on request, a clean summary per candidate: check type, date, certificate or reference number, and verifier. An agency that can only say "yes, we did the check" without being able to produce the specifics is putting the school in a position where it cannot properly complete its own record, which becomes the school's finding at inspection, even though the root cause sits with the agency.

The mandatory checks columns

Every one of these columns needs a date and a reference, not just a tick. An SCR that records "DBS: yes" without a certificate number and check date is not meaningfully different, from an inspection standpoint, to an SCR with no DBS entry at all, because it cannot be independently verified.

Common gaps found in audits

• Supply staff missing from the SCR entirely because the school assumed the agency was maintaining a separate record
• Check dates that predate the placement by several months with no re-verification in between
• No record of who at the agency or school actually verified each document
• Right to Work checks that were valid at onboarding but have since expired without a re-check
• Prohibition checks that were run once but never repeated for long-running placements
• Inconsistent formatting or missing fields that make the record difficult to audit quickly, even where the underlying checks were sound

Nearly all of these come down to the same root cause: a candidate pool that changes faster than a manual record can keep up with. A spreadsheet updated at the point of onboarding is accurate on day one and steadily less accurate every day after that, unless something is actively monitoring it and flagging what has changed.

Keeping the SCR current with a churning candidate pool

The practical answer is to treat the SCR as a live view of current status, not a one-time onboarding record. That means re-checking Right to Work documents as they approach expiry, monitoring DBS Update Service status rather than trusting the original certificate date indefinitely, and flagging any candidate whose compliance record has gone stale before they are booked into another placement.

It also means having a single source of truth rather than parallel records held by different consultants on different desks. A supply teacher who works across two or three schools through the same agency should have one compliance record that every consultant references, not three slightly different versions depending on who onboarded them first.

scout. maintains SCR data as a continuously updated record rather than a point-in-time snapshot, every candidate's DBS, Right to Work and prohibition check status is tracked automatically, and gaps are surfaced before a placement goes out, not discovered afterwards during an audit. For more on how the compliance tracking works day to day, see our guide on DBS checks for education supply agencies, and for the practical checklist version of this see our Ofsted readiness checklist.

Building an SCR process that survives staff turnover at the agency

One gap that rarely gets discussed is what happens to SCR record-keeping when the consultant who onboarded a candidate leaves the agency. If compliance detail lives in that person's inbox, their personal spreadsheet, or their memory of "I definitely chased that DBS renewal," it leaves with them. The record should be structured so that any compliance lead at the agency can pick up any candidate's file and immediately see what has been checked, when, and what is outstanding, without needing to ask around or dig through old email threads.

This matters more for supply agencies than for most other recruitment sectors, because the compliance record for a single candidate can span months or years and multiple schools, and desks change hands more often than client relationships do. A record that depends on institutional memory is a record that degrades every time someone changes role.

A simple monthly SCR health check

Rather than waiting for a school or an inspection to surface a gap, it is worth running a short internal audit on a fixed schedule:

• List every candidate currently on an active placement across all client schools
• Confirm each has a complete row on the SCR with no blank fields
• Check that DBS, Right to Work and prohibition check dates are all still within an acceptable currency window
• Spot-check three or four records at random for completeness, rather than only reviewing ones already flagged as a concern
• Note any candidate approaching a compliance deadline in the next 30 days and confirm a chaser is already in motion

Run consistently, this turns SCR management from a reactive scramble into routine maintenance, which is exactly the posture that holds up under an Ofsted inspection with half a day's notice.

Doing this monthly check by hand means someone manually cross-referencing a spreadsheet against every active placement; a system like scout. runs this same check continuously in the background and surfaces any incomplete row before it is ever due for review.
