§ 05 - Editorial notes
Company overview
Codility (Codility Limited), founded in 2009 by competitive-programmer Greg Jakacki and headquartered in London with engineering and product teams in Warsaw, is a technical hiring platform. Its products - Screen (work-sample coding assessments), Interview (live technical interviews, including an AI Copilot), and Skills Intelligence - are built around I/O-psychology methodology, deterministic auditable scoring, and integrity controls (identity verification, behavioral monitoring, cheating-app and plagiarism/AI-code detection). The company advertises SOC 2 Type II, ISO 27001, GDPR compliance, and WCAG 2.2 AA accessibility, with EU/US data residency on AWS.
Regulatory exposure
Assessment tools used to substantially assist employment decisions fall under EU AI Act Annex III (high-risk), NYC Local Law 144 (AEDTs), and emerging Illinois/Colorado AI laws, and Codility markets directly to EU and NYC employers. Codility's stated posture reduces some exposure: it says no AI or machine learning makes an automated hiring decision, scoring and integrity risk levels are deterministic and rule-based, and a human always decides - which is designed to keep tools outside the strictest AEDT/Article-22 automated-decision triggers. However, deployer obligations (bias audit, human oversight, transparency, adverse-impact monitoring) still attach to customers, and Codility's own EU AI Act alignment is described as a roadmap ahead of the August 2026 deadline rather than completed conformity.
Path to a higher score
The largest gaps are independent, published bias evidence and formal AI-Act artifacts. Codility could raise its score by commissioning and publicly posting an independent third-party bias/NYC LL 144 audit (e.g., BABL AI, Warden AI, Holistic AI) rather than customer-specific analyses gated in its Technical Manual; publishing the Technical Manual and adverse-impact methodology; releasing a model card for its AI-detection and AI-Assistant components; pursuing ISO 42001; and providing an EU AI Act Article 27 Fundamental Rights Impact Assessment template and completed conformity documentation for deployers.
§ Regulatory frame
What applies to assessment ai.
Assessment is the most-regulated surface in AI hiring. NYC LL 144, EEOC and OFCCP frameworks, Illinois HB 3773, and EU AI Act Annex III §4 all apply, with overlap on bias-audit obligations.
