Allegheny Family Screening Tool
Evaluation evidence on the Allegheny Family Screening Tool found that screener overrides of the tool's recommendations reduced racial disparity in screen-in rates relative to the tool alone.[3]
What happened
Allegheny County's Family Screening Tool scores child-maltreatment referrals to support call-screening decisions, and is unusual for the depth of its public documentation: methodology reports, an independent impact evaluation, and sustained academic and journalistic scrutiny. That record includes findings on racial disparity in screen-in rates — and, notably, evaluation evidence that screener overrides of the tool's recommendations reduced the disparity relative to the tool alone, alongside long-running community and researcher criticism of using such tools at all.
The sociotechnical reading
AFST reframes "human in the loop" from a checkbox into a measurable component: here, the operator network demonstrably changed the system's equity behavior, in the protective direction. That cuts both ways — a system whose fairness depends on engaged overrides inherits every fragility of the humans doing the overriding (workload, deference drift, deskilling). It is the Atlas's clearest bridge to the deskilling and vigilance material in the Field Guide: the safeguard is alive, so it must be maintained like something alive.
The concepts used in this reading are defined in the Field Guide; the governance responses live in the Practice Library. A stylized system in this case's shape can be stress-tested in the PAN Lab.
