When 60% of approved AI systems mix up prescribed drugs and nine out of 20 fabricate treatment suggestions, you don't have a model performance problem. You have an evaluation design problem.
The Office of the Auditor General of Ontario's recent audit of AI Scribe systems reveals what happens when procurement scorecards prioritize vendor presence over clinical accuracy. The result: systems that routinely insert hallucinated content into patient records while passing evaluation with flying colors.
If you're validating AI for high-stakes deployment, this template gives you a starting point for building evaluation criteria that actually measure what matters.
Purpose of the Template
This scorecard template structures pre-deployment evaluation of AI systems intended for clinical or other high-consequence environments. It's designed to prevent the evaluation failures that allowed inaccurate AI Scribe systems into Ontario healthcare settings.
Use this when you're:
- Evaluating vendor AI systems for procurement
- Designing acceptance criteria for internally developed clinical AI
- Auditing existing evaluation frameworks for adequacy
- Building validation evidence for regulatory submissions
This isn't a model card or technical documentation template. It's the scoring framework you use to decide whether an AI system is fit for deployment.
Prerequisites
Before you apply this template, you need:
Test data that reflects real-world conditions. The Ontario evaluation used simulated doctor-patient recordings reviewed by medical professionals. Your test set must represent the actual distribution of cases, edge conditions, and input quality your system will encounter.
Domain-qualified reviewers. Clinical AI requires clinical reviewers. You can't evaluate medical accuracy without medical expertise in the loop.
Clear performance thresholds. Define your minimum acceptable accuracy, recall, and precision before you score vendors. If you can't articulate what "good enough" means for patient safety, you're not ready to evaluate.
Regulatory context. Know which requirements apply. ISO/IEC 42001's controls for AI management systems, ISO/IEC 5338's lifecycle requirements, or SR 11-7's model risk management expectations may all inform your criteria.

How to Customize It
Adjust weights for your risk profile. If you're deploying in a jurisdiction with strict liability for AI errors, increase the clinical accuracy section weight to 60-70% and reduce operational readiness accordingly.
Define your safety-critical categories. The template lists common categories, but your clinical context determines what's actually critical. A mental health AI has different safety-critical fields than a radiology assistant.
Set evidence standards for bias testing. Specify: sample size per demographic group, statistical tests used, acceptable variance thresholds, and required documentation format.
Align minimum thresholds with regulatory requirements. If you're subject to the EU AI Act's high-risk requirements, your accuracy thresholds need to reflect Annex IV documentation standards and conformity assessment expectations.
Add domain-specific criteria. Radiology AI needs different evaluation criteria than clinical note generation. Include specialty-specific accuracy measures where relevant.
Build in validation evidence requirements. If you need to demonstrate SR 11-7 compliance, add a section requiring validation documentation that maps to conceptual soundness, ongoing monitoring, and outcome analysis.
Validation Steps
After you've customized the scorecard, validate it before you deploy:
Run a pilot evaluation. Score 2-3 systems you already understand well. Do the scores match your intuitive assessment of their fitness? If your best-performing system scores poorly, your criteria or weights need adjustment.
Check for gaming vulnerabilities. Can a vendor optimize for your scorecard while still producing unsafe outputs? The Ontario evaluation gave 30% weight to regional presence. That's easily gamed and clinically meaningless.
Verify reviewer agreement. Have multiple qualified reviewers score the same system independently. If they diverge significantly on Section 1 scores, your clinical accuracy criteria aren't specific enough.
Test against known failures. If you have access to AI systems that failed in production, score them retroactively. A good scorecard should have caught them.
Document your rationale. For each weight and threshold, write one sentence explaining why. "Drug information accuracy is 15 points because medication errors have immediate patient safety consequences and are difficult for clinicians to catch in review." This documentation becomes your validation evidence.
The Ontario audit found that accuracy contributed 4% to vendor scores while regional presence counted for 30%. That's not an evaluation framework. It's a procurement checklist that happens to mention accuracy.
Your scorecard determines what you deploy. Weight it accordingly.
