§ The result
Versant by Pearson leads XOR on all 7 criteria.
Versant by Pearson finishes 19 points clear of XOR under rubric v1.0 — 49 against 30 — across the Assessment and Screening cohorts. Versant by Pearson leads every one of the 7 criteria, XOR none of them, and the closest of the 7 is FRIA Support, Versant by Pearson 30 to XOR 25. One criterion, Article 11 Technical Documentation, is both the widest raw gap (Versant by Pearson 63, XOR 20) and the heaviest weighted swing, and at 20% weight it makes up 44% of the weighted advantage Versant by Pearson holds across the 7 criteria it leads.
Vendor profile
Versant by Pearson
Versant by Pearson is a suite of AI-scored English proficiency tests (plus spoken Spanish, French, Arabic and Dutch) that automatically score candidates' spoken and written responses on Pearson's Global Scale of English within minutes, used by employers such as contact centres and BPOs to screen applicants and benchmark staff through the ScoreKeeper dashboard.
Vendor profile
XOR
XOR is a text-first conversational-AI recruiting platform that pre-screens and scores high-volume and hourly candidates with recruiter-defined knockout/scoring questions over SMS, WhatsApp, and Messenger, then auto-schedules interviews on the recruiter's calendar.
§ The record
Versant by Pearson is filed under Assessment AI, XOR under Screening AI. They record no secondary category in common.
Both are in scope of NYC LL 144, Illinois HB 3773, EU AI Act and Colorado AI Act. Only Versant by Pearson is in scope of Mobley v. Workday.

Weighted delta is the raw difference times the criterion weight, so the 7 figures above sum to +19.5 — the difference between the two totals before either is rounded. Shares are of 19.5 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads +19 beside that +19.5.

§ Evidence
Cited sources and documented absences, criterion by criterion.
An absence is a finding, not a blank: the reviewer looked for a named artefact and recorded that it is not located. Where a source sits is a fact about hosting only.
