Water Hygiene management is a high-risk, high-consequence discipline. Decisions made by Duty Holders, Responsible Persons (Water), Authorised Persons (Water), and technicians directly influence patient safety, regulatory compliance, and organisational liability.

A person who has been “trained” but is not yet competent may:

• Misinterpret monitoring data
• Fail to recognise early signs of deterioration
• Carry out tasks incorrectly or unsafely
• Miss critical escalation points
• Assume they understand the system when they do not

In healthcare environments, the gap between training and competency can translate into real harm. HTM 04-01, HSG274, and BS 8680 all emphasise the need for competent persons, not simply trained ones.

So how do we define competency in a way that is meaningful, measurable, and aligned with real-world performance?

The S.K.A.T.E. Model of Competency

Competency is multidimensional. It’s not a certificate, a job title, or a number of years served. It’s a blend of attributes that enable someone to perform safely, effectively, and consistently.

The S.K.A.T.E. model captures this perfectly:

Skill

The practical, hands-on capability to perform tasks correctly — from aseptic sampling (BS 7592) to temperature monitoring, flushing, TMV maintenance, and interpreting system behaviour.

Knowledge

Understanding the “why” behind the task: legislation, guidance, system design principles, microbiology basics, and risk factors.

Ability / Attitude

The personal attributes that shape performance: attention to detail, ownership, curiosity, willingness to escalate, and confidence to challenge unsafe practices.

Training

Formal instruction that introduces concepts, standards, and expectations. Training provides the foundation — but without the other elements, it remains theoretical.

Experience

Exposure to real systems, real problems, and real decision-making. Experience builds judgement, pattern recognition, and the ability to respond appropriately under pressure.

Why S.K.A.T.E. should matter to organisations

Relying solely on training creates a false sense of security. A certificate may satisfy a procurement checklist, but it doesn’t guarantee safe practice.

The S.K.A.T.E. model helps organisations:

• Assess individuals holistically
• Identify gaps training cannot fill
• Build structured development pathways
• Strengthen governance and assurance
• Reduce risk by placing the right people in the right roles

It also supports Responsible Persons (Water) in demonstrating due diligence — something increasingly scrutinised by auditors, regulators, and insurers.

Competency is a journey, not an event

Competency develops over time through mentoring, supervised practice, reflective learning, and exposure to varied scenarios. It requires feedback, assessment, and ongoing support.

Training courses can establish important foundations, but they cannot replace:

• Shadowing experienced engineers or consultants
• Real-world troubleshooting
• Understanding site-specific systems
• Learning from incidents and near misses
• Continuous professional development

In Water Hygiene, competency isn’t a badge — it’s a responsibility.

The role of the Authorising Engineer (Water)

An Authorising Engineer (Water) plays a pivotal role in bridging the gap between training and true competency. Acting as an independent assessor and advisor, the AE(W) provides objective scrutiny of both individuals and systems.

Through audits, interviews, and competency reviews, the AE(W) validates that Responsible Persons (Water), and their deputies possess not only the required training but also the demonstrable skills, knowledge, ability/attitude, and experience to manage water safety effectively.

This strengthens organisational assurance — confirming that competency is not assumed, but evidenced, maintained, and continually developed.

Final Thought

If we want safer systems and stronger compliance cultures, we must shift our mindset:

Training creates awareness. Competency creates safety.

The S.K.A.T.E. model gives organisations a practical framework to build, assess, and maintain competency — ensuring the people managing our water systems are not just trained, but truly capable.
