NYC Local Law 144 · AEDT Bias Audit
Evidence-ready support for NYC Local Law 144 bias audits
Determine whether the system is in scope, prepare the required data, calculate the required selection or scoring results, document the audit method, and keep the evidence behind the result together.
In force since July 5, 2023. Formal bias audit, monitoring/readiness, and notice/disclosure support are separate workflows — not one legal verdict.
What Local Law 144 requires
Employers using an AEDT for NYC hiring or promotion decisions must meet three obligations, enforced by DCWP.
Annual bias audit
An independent auditor calculates selection or scoring rates and impact ratios by sex, race/ethnicity, and intersectional categories — before the AEDT is used and annually thereafter.
Candidate notice
Candidates must receive notice — including the AEDT used, the job qualifications and characteristics assessed, and how to request an alternative process — at least 10 business days before use.
Public disclosure
A Summary of Results — rates, impact ratios, source data explanation, unknown counts, audit date, and distribution date — must be published publicly and kept current.
Statutory penalties range from $500 for a first violation to up to $1,500 for subsequent violations per day. How daily-use and notice violations are counted depends on the violation class and the facts of your situation — scope and exposure are engagement-specific, not a fixed formula.
Three separate workflows
What HAIEC provides — and what it does not decide
A statistical signal is not a legal verdict. Each workflow produces evidence with explicit boundaries.
Formal bias audit
Audit support & calculation
Selection-rate and scoring-rate calculation, impact ratios, intersectional breakdown, documented exclusions, and the evidence chain an independent auditor reviews.
- EEOC 4/5ths-rule analysis
- Impact ratio calculation
- Intersectional category breakdown
- Documented audit method
Monitoring / readiness
Ongoing bias monitoring
Scheduled statistical monitoring of hiring decisions between formal audits — readiness evidence, not a substitute for the formal audit.
- ATS webhooks (Greenhouse, Lever, Workday)
- CSV upload for any system
- Threshold alerts
- PII hashed on ingestion
Notice / disclosure support
Candidate notice & disclosure
LL144-aligned notice workflows, delivery evidence, and hosted, versioned Summary of Results pages.
- Notice templates & timing
- Delivery tracking & proof
- Hosted disclosure pages
- Version history

How the audit workflow runs
From scoping to published disclosure, with the evidence bound at each step.
Scope the system
Determine whether the AEDT and its use are in scope: which decisions it supports, which candidates it touches, which data is required.
Prepare the data
Connect ATS webhooks or upload CSV. Candidate and job IDs are hashed on ingestion — raw PII is never stored.
Calculate the results
Selection rates, scoring rates, impact ratios, and intersectional categories are computed with a documented method and documented exclusions.
Audit, publish, monitor
An independent auditor reviews the analysis. The Summary of Results is published and versioned. Monitoring continues between formal audits.
Monitoring is not the formal audit
The monitoring engine produces ongoing readiness evidence — statistical signals between audits. The formal annual bias audit required by LL144 is a separate, engagement-scoped process conducted by an independent auditor. Independence is assessed and documented for the specific audit engagement; the platform itself is not the auditor.
Engagement, not a checkbox
Audit scope and pricing depend on the AEDT, the data, and the audit boundary — they are scoped per engagement, not sold as a self-serve subscription line item.
What the engagement covers
- AEDT scoping and data readiness review
- Documented calculation method and exclusions
- Evidence pack for the independent auditor
- Summary of Results publication workflow
What remains yours
- The legal determination of whether the tool is an AEDT
- Independent auditor independence — assessed per engagement
- Publication and notice decisions
- Interpreting a statistical signal as a legal verdict
Platform plans for ongoing monitoring are on the pricing page.
Scope review
Request a Local Law 144 scope review
Tell us about the AEDT and how it is used. We will scope the audit boundary, the data required, the calculation method, and the auditor relationship — then confirm what the engagement covers.

Get the audit boundary, the calculation, and the evidence — together.
Scope review first. Formal audit, monitoring, and disclosure support stay separate — so every result carries exactly the evidence it earned.
