Vendor & Auditor Due Diligence

Four-Fifths Rule & Impact-Ratio Reading Guide (PDF + Companion Calculator)

Read what a vendor's published Local Law 144 bias audit actually reports — selection rates, impact ratios, the four-fifths reference point, and sex-by-race/ethnicity intersectional cross-tabs — with a plain-English PDF guide and an Excel companion for transcribing those already-published figures alongside their cited source. You never compute or certify an audit here; you read one that already exists and record what it says. The guide walks through each section of a typical audit summary and flags where a published summary is incomplete, stale, or ambiguous. Every number in the companion workbook is your own transcription of a public source you cite — no benchmark, default, or industry figure is supplied.
