Annex IV Template: A Complete Guide

What is an Annex IV template?

An Annex IV template is a structured document framework that providers of high-risk AI systems must complete to demonstrate compliance with EU AI Act requirements. Article 11 mandates that all high-risk AI systems come with comprehensive technical documentation covering nine specific sections. The template ensures you don't miss critical compliance information.

Unlike generic compliance checklists, an Annex IV template walks you through the exact documentation structure regulators expect, reducing ambiguity and minimizing the risk of rejection during notified body review.

The template requirement applies to providers of high-risk AI systems — companies that develop, integrate, or modify AI systems before placing them on the EU market. It does not apply to deployers (organizations using AI systems), though deployers of certain Annex III systems must conduct a FRIA (Fundamental Rights Impact Assessment).

What should an Annex IV template contain?

Annex IV specifies nine mandatory documentation sections. A complete template must address all of them:

1. System purpose and intended use

Describe what your AI system is designed to do, its primary function, and the context in which it will be used. Include the target users (law enforcement, credit institutions, HR teams, etc.) and any limitations on intended use. This section should be clear enough that a regulator can immediately understand what the system does.

2. Development process and methodology

Document how the system was developed, including the architecture, algorithms used, design choices, and integration approach. Explain the AI development methodology, any third-party components, and how the system was built to meet high-risk requirements.

3. Training data characteristics

Provide comprehensive information about the training data: size, origin, collection methodology, data preprocessing steps, and statistical properties. Explain how data was labeled, validated, and selected. Include details on data imbalance, outliers, and any known biases in the training dataset.

4. Testing and validation results

Document all testing performed: unit tests, integration tests, validation tests, and stress tests. Report performance metrics (accuracy, precision, recall, F1 score, etc.), testing methodology, test datasets used, and results under various conditions. Include performance across different demographic groups to demonstrate fairness and non-discrimination.

5. System performance and limitations

Detail the system's performance boundaries: accuracy rates, latency, throughput, and resource consumption. Explicitly state known limitations, failure modes, and circumstances where the system may perform poorly. Include any edge cases or scenarios where human intervention is required.

6. Risk management and mitigation

Document your risk management system (Article 9 compliance). Describe identified risks, risk assessments performed, mitigation strategies implemented, residual risks, and ongoing monitoring procedures. Include risk assessment documentation and evidence of how risks are managed throughout the system lifecycle.

7. Data governance and quality

Explain data governance practices (Article 10 compliance). Describe data quality measures, data retention policies, mechanisms to prevent data drift, and procedures for updating training and validation data. Include information about data provenance, consent, and legal basis for data use.

8. Human oversight and oversight procedures

Document human oversight mechanisms (Article 14 compliance). Explain how humans monitor system outputs, identify failures, and intervene. Include training procedures for human operators, decision-making workflows, and circumstances triggering human review. Describe technical measures enabling meaningful human oversight.

9. Post-market monitoring

Describe your post-market monitoring plan (Article 72 compliance). Document how you monitor system performance after market deployment, procedures for collecting user feedback, incident reporting mechanisms, and processes for addressing identified issues. Include timelines for data analysis and corrective action.

Free vs. paid templates: What's the difference?

Not all Annex IV templates are created equal. Understanding the difference between generic templates and AI-generated documentation is crucial for compliance.

Generic PDF templates

Free or low-cost PDF templates typically offer: (1) Static structure — a fixed list of sections copied from Annex IV verbatim; (2) No guidance — minimal explanation of what each section requires or how to fill it; (3) Outdated context — templates created months or years ago don't reflect current regulatory guidance or notified body expectations; (4) One-size-fits-all format — no consideration of your system's unique architecture or industry.

AI-generated, role-specific documentation

Conformy and similar AI-powered tools generate documentation that is: (1) Dynamic and contextual — questions adapt based on your system type, industry, and risk profile; (2) Authoritative guidance — each section includes explanations of regulatory requirements, best practices, and common pitfalls; (3) Always current — AI tools can update instantly as guidance evolves; (4) Role-specific — templates tailored to your company's role (provider, importer, distributor) and your system's characteristics (biometric, law enforcement, HR, etc.).

Generate your Annex IV documentation

Instead of starting from a blank PDF template, use Conformy's AI-powered documentation generator to create tailored, authoritative Annex IV documentation in minutes.

Here's how it works:

1. Classify your AI system using our free tool. Answer a few questions about your system's purpose, capabilities, and risk factors. We'll determine if it's high-risk and what requirements apply.
2. Review your compliance requirements. See which articles (9, 10, 14, 17, etc.) apply to your system and what documentation is needed.
3. Generate Annex IV documentation. Answer detailed questions about your development process, training data, testing, and monitoring. Our AI compiles your answers into a structured, publication-ready Annex IV document.
4. Download and share. Export your documentation as PDF or DOCX, review it with legal counsel or a compliance specialist, and submit to your notified body.
