When Trust Becomes a Safeguarding Risk

By Tim Stokes, Sales Director, Matrix Security Watchdog

In early 2025, the education sector was confronted with a reminder that the people we place in positions of trust are not always who they claim to be. A former head of sixth form at a private school in Cheltenham was struck off after it emerged he had fabricated both a degree from the University of Cambridge and a record of service as a magistrate. Two credentials. Both false. Both unchallenged until it was too late.

For many schools and educational institutions, the immediate reaction may be one of disbelief. How could something like this happen? The harder question is: how confident are you that it couldn’t happen in your institution?

A Wake-Up Call the Sector Cannot Ignore

The Cheltenham case is not an anomaly. It’s the visible tip of a much larger and growing problem – credential fraud. 

Categorised as the fabrication or misrepresentation of qualifications job titles, professional memberships, and other background details, credential fraud is on the rise across every sector. But in education, the stakes are uniquely high.

Schools are hiring individuals who will spend hours each day in contact with children and young people. The trust placed in those individuals is pastoral, ethical, and in many cases legal. When that trust is misplaced, the consequences can be devastating and long-lasting.

Yet many institutions continue to reply on hiring processes that were designed for a different era and a different threat landscape.

The Fraud Landscape Has Changed Dramatically 

It would be a mistake to think of credential fraud as a fringe activity carried out by a small number of reckless individuals. The reality is far more organised, far more accessible, and far more convincing than most hiring managers appreciate.

The rise of diploma mills – organisations that sell fake or unaccredited degrees, diplomas, and professional certificates – has accelerated in recent years. A convincing-looking certificate from a prestigious institution can now be purchased online at a low cost, complete with verification hotlines and fabricated transcripts designed to withstand casual scrutiny.

AI has added a new and concerning dimension to this problem. Generative tools can now produce highly convincing forged documents that are increasingly difficult to distinguish from the genuine article through visual inspection alone. Candidates are also becoming more sophisticated in the way they construct fraudulent histories. Rather than elaborate fabrications that may unravel quickly, many now make targeted embellishments such as inflating the prestige of a real qualification, claiming membership of a professional body they once belonged to, or referencing a role at a previous employer that was more junior than stated. These partial frauds are harder to detect and are often designed specifically to pass surface-level checks.

The Limits of Traditional Hiring Practices

In my experience, many organisations believe their hiring processes are more robust than they are. But in practice, many of the steps traditionally undertaken – interviews, requests for original certificates, DBS checks, references – have significant limitations when it comes to detecting deliberate fraud.

Interviews are designed to assess capability, not uncover deception. References are frequently superficial. DBS checks are an essential safeguarding tool, but they reveal criminal history, not credential fraud. Visual inspection of documents tells you little about their authenticity in the age of high-quality forgeries and AI-generated paperwork.

The gap between what organisations believe their screening process delivers and what it actually delivers is where fraudulent candidate continues to operate – undetected, unchallenged, and in post.

In Education, the Cost of Getting it Wrong

Across many industries, a bad hire can be an operational and financial problem. In education, it’s a different story. A fraudulent hire in a school or college represents a potential safeguarding issue. A person in a position of trust, working with vulnerable young people, whose background, qualifications, and character have not been properly verified can, in the worst cases, represent a direct risk of harm.

And even when no direct harm occurs, the reputational consequences are severe and long-lasting. Leadership teams are scrutinised. Parents lose confidence. Ofsted and regulatory bodies take notice. Institutions will carry the shadow of incidents long after the individual has moved on.

What Robust Screening Actually Looks Like

Effective pre-employment screening goes well beyond document collection and reference chasing. It involves systematic, technology-supported verification of candidate claims – cross-referenced against authoritative data sources and designed to uncover discrepancies before they become problems.

The key principle is that verification must be active, not passive. Collecting documents and accepting them at face value isn’t screening. Confirming through independent and authoritative sources that the information a candidate has provided is accurate – that is screening. 

The Cheltenham case will not be the last of its kind. As long as credential fraud remains easy to commit and difficult to detect through standard hiring practices, motivated individuals will continue to exploit the gaps. Educational institutes should ask themselves whether their screening processes are designed to find fraudulent candidates.

In education, there is zero margin for error. If we allow corners to be cut in recruitment, we undermine the very values we teach. With the advancement of AI-generated fraud and deep fake, the human eye is no longer enough to spot a forgery. We must move from a culture of assumption to a culture of verification. True due diligence isn’t a hurdle to hiring – it’s the foundation of a safe, high-integrity learning environment.
