NYC Local Law 144 — Automated Employment Decision Tools (AEDT)
New York City Local Law 144 (effective 2023-07-05) requires annual independent bias audits and candidate notices for Automated Employment Decision Tools (AEDTs) used in hiring or promotion decisions affecting NYC residents. Ledgix evidences the bias-audit, impact-ratio, and selection-rate requirements with signed bias audit reports stratified by protected-attribute group.
Status: Full — every control resolves to an artifact Ledgix produces today following the Phase 3 bias-audit module shipping.
Scope
LL144 applies to employers and employment agencies using AEDTs to substantially assist or replace discretionary decision-making in employment decisions for residents of New York City. Coverage spans the annual independent bias audit (§ 5-303(a)), impact-ratio calculation (§ 5-302(b)(1)), selection-rate calculation (§ 5-302(b)(2)), public summary (§ 5-304), candidate notice (§ 5-305), and AEDT decision recordkeeping (§ 5-301).
Controls covered
| Field | Type | Required | Description |
|---|---|---|---|
| LL144-5-303(a) | bias_audits | Annual Bias Audit by Independent Auditor | Per-window signed bias audit reports with impact ratio and selection rate per protected category. |
| LL144-5-302(b)(1) | bias_audits | Impact Ratio Calculation | four_fifths_ratio field per group (ratio < 0.80 indicates disparate impact). |
| LL144-5-302(b)(2) | bias_audits | Selection Rate Per Category | approval_rate per protected-attribute group. |
| LL144-5-304 | bias_audits | Public Summary of Bias Audit Results | Summary-ready bias audit records with explicit pass/fail at 0.80 threshold. |
| LL144-5-305 | policy_snapshots / model_cards | Notice to Candidates and Employees | Versioned policies defining qualifications plus model cards describing assessed characteristics. |
| LL144-5-301 | events_jsonl / checkpoint_chain | AEDT Definition and Decision Records | Per-decision employment action records with agent_id, action_category, approval outcome, plus Merkle checkpoint chain. |
Evidence types referenced
- bias_audits — signed per-window audit reports with four-fifths, chi-square, and selection-rate data per protected-attribute group.
- policy_snapshots — versioned policies defining the qualifications/criteria used by the AEDT.
- model_cards — model cards describing characteristics assessed by the underlying AEDT model.
- events_jsonl — per-decision employment action records.
- checkpoint_chain — Merkle checkpoint chain proving immutable retention of AEDT decision history.
Known gaps (if any)
None — every control resolves to an artifact Ledgix produces today. Bias audits require tenant-provided subject_context tagging for demographic stratification; the independent-auditor step is performed outside Ledgix and typically attached as a signed document reference on the audit record.
