Deterministic Eligibility and Compliance for the Public Sector.

Compile statute, regulation, and program policy into governed decision packages. Determine eligibility and enforce compliance deterministically — with full provenance, statute-linked reason codes, and an immutable audit trail. AI assists at build time; every determination is reproducible and defensible on appeal.

The problem in government

Eligibility decisions are inconsistent — and appealable

Caseworkers apply the same statute and policy manuals differently, so identical applicants receive different determinations. Denials get appealed and overturned at fair hearings. Eligibility rules should be deterministic and auditable — not dependent on which office or worker handles the case.

Policy is trapped in statute and manuals

Eligibility criteria and program rules live in codes of regulations, state plans, and policy manuals that no system can execute consistently. Sertainly compiles them into governed, versioned decision packages with citations back to the governing clause.

Rule changes and audits require reconstruction

Income limits, benefit tables, and program rules change every year — often mid-year. Proving which rules applied to a determination made last spring means weeks of archaeology. Every decision should replay against the rules in force on its own effective date.

How Sertainly Helps

Benefits Eligibility Determination

Program rules — income and asset tests, household composition, categorical eligibility — compiled into deterministic decision packages linked to the governing statute and policy manual.

  • Income and asset threshold tests against program-specific limits
  • Household composition and categorical-eligibility rules
  • Structured evidence request when verification documents are missing
  • Full trace with statute and regulation citations for fair-hearing appeals

Licensing & Permitting

Professional licensing and permitting requirements compiled into governed decision packages — eligibility, disqualifying conditions, and renewal rules executed the same way every time.

  • Requirement checks against statute and administrative code
  • Disqualifying-condition and background screening rules
  • Renewal, continuing-education, and reciprocity determinations
  • Version-pinned rule logic with source-regulation provenance

Program & Grant Eligibility

Eligibility for assistance programs, grants, and subsidies evaluated deterministically by applicant profile — with traceable reason codes for oversight.

  • Eligibility criteria evaluation by applicant and entity profile
  • Funding priority and tier rules with transparent scoring
  • Duplication and conflict-of-benefit checks
  • Reason codes traceable to program rules for IG and oversight review

Tax Credit & Eligibility Determination

Tax credits, deductions, exemptions, and liability rules compiled into deterministic decision packages — computed against the code in force for the relevant tax year.

  • Credit and exemption eligibility against statutory thresholds
  • Liability and withholding calculations with traceable reason codes
  • Every determination computed with the rules in force for its tax year
  • Signed trace with code citations for examination and appeal

Appeals & Audit Defensibility

Every determination carries a signed trace and replays against the exact rules in force on its effective date — so a decision made last year is reproducible today.

  • Signed decision trace for fair-hearing and administrative appeal
  • Reproduce any past determination against the rules in force on its date
  • Reason codes cited to the governing statute or regulation
  • Immutable audit trail for oversight, IG, and legislative review

Benefits eligibility: SNAP determination

An application is submitted for evaluation. Sertainly runs the program’s income and verification tests and returns a deterministic determination with full trace.
