How Much AI Training Is 'Sufficient'? The Proportionality Principle

Understanding the Issue

The amount depends on: AI system risk level, impact of AI-assisted decisions, staff technical background, and context of use. Receptionist using scheduling AI needs less than HR manager screening candidates.

This is a concern that affects businesses of all sizes. Small businesses may face higher relative impact because they have fewer resources to recover from AI-related problems. Understanding the issue is the first step toward managing it effectively.

The Proportionality Factors

Article 4 requires literacy that is 'sufficient' taking into account the technical knowledge, experience, education, and training of the persons, as well as the context in which the AI systems are to be used. This means the required level varies based on who the person is and what AI they use.

Proportionality prevents both under-training (not enough for the risk) and over-training (requiring expertise that isn't needed).

Practical Guidelines

For staff using low-risk AI (email tools, scheduling): 1-2 hours of basic awareness is likely sufficient. For staff using AI for client work (document drafting, analysis): 2-4 hours covering tool capabilities, verification, and data handling. For staff using AI for consequential decisions (hiring, credit, safety): 4-8 hours covering the above plus risk management, bias awareness, and oversight responsibilities.

These are guidelines — adjust based on your specific tools, risks, and team.

Documenting Proportionality

Document your reasoning for the training levels you provide. Explain why you determined that a particular level is 'sufficient' for each role or group. This shows regulators that you've thought about proportionality rather than applying a one-size-fits-all approach.

If challenged, you want to demonstrate that your training investment was proportionate to the risks involved.
