Summary

Implements Nevada's Child Care and Development Program (CCDP) — the DWSS child care subsidy funded through the federal Child Care and Development Fund (CCDF). The subsidy pays a provider-day rate (by region, provider type, and child age) up to the state maximum, less a flat income-tier family copay, capped at actual childcare expenses. Eligibility uses a two-tier State Median Income (SMI) test, Nevada residency, child citizenship, a $1M asset limit, and a qualifying-activity (Purpose of Care) requirement.

Closes #8664.

Source-precedence caveat: The July 2024 Policy Manual's copay (MS 170/180) and income-eligibility sections are outdated — they still describe the pre-October-2024 sliding-scale copay (0-7% of income) and a single 85% SMI eligibility test. The Oct 2024 flat-copay change documented in CC PT 06-25 and the two-tier SMI eligibility in the FFY 2025-2027 CCDF State Plan are authoritative for the current flat copay and the 41%/49% SMI tiers. The Policy Manual is used only for rules that were not superseded.

Eligibility

Income & SMI tiers

Nevada uses State Median Income, not the federal poverty line. nv_ccdp_smi returns monthly 100% SMI via the federal smi() helper, pinned to the October-1 chart effective date (the chart updates annually on Oct 1). nv_ccdp_income_eligible then applies the tier ratio to monthly SMI:

• New applicants (intake): countable income ≤ 41% SMI (income/smi_intake.yaml).
• Enrolled families (renewal/redetermination): countable income ≤ 49% SMI (income/smi_renewal.yaml). This is the renewal ceiling and matches the top of the published copay scale exactly.

The federal CCDF rules also define an 85% SMI mid-certification-period protection (45 CFR 98.21(a)(1)(ii)): a state may not terminate a family mid-certification until income exceeds 85% SMI. PolicyEngine does not track certification periods at the moment, so this mid-period protection is not enforced. The operative enrolled income ceiling in the model is the 49% renewal tier; the 85% protection is documented as a limitation in nv_ccdp_income_eligible, not modeled.

Benefit Calculation

subsidy = max(min(provider charge, state max monthly rate) − flat family copay, 0)
          capped at actual childcare expenses

• State max monthly rate = per-day rate × billed days, where the per-day rate comes from a base-rate table keyed by 2-region (Clark vs. rest-of-state) × provider type (center / family child care) × age group (infant / toddler / preschool / school-age). nv_ccdp_provider_rate looks up rates/center.yaml or rates/fcc.yaml; nv_ccdp_region derives the region from county; nv_ccdp_age_group derives the age band from age in months.
• Flat family copay (nv_ccdp_copay, keyed by % SMI): $0 (≤32.99% SMI), $90 (33-42% SMI), $150 (43-49% SMI). Waived (set to $0) for TANF-NEON referrals (is_tanf_enrolled), CPS/foster placements (is_in_foster_care / receives_or_needs_protective_services), and homeless households (is_homeless).
• Per-child reimbursement is summed over eligible children in care, the family copay is subtracted once at the family level, and the result is floored at 0.

Requirements Coverage

20 of 20 in-scope requirements are covered.

(Supporting input enum nv_ccdp_provider_type and the nv_ccdp_enrolled input boolean each have their own test.)

Not Modeled

Microsimulation note

nv_ccdp returns $0 in microsimulation because meets_ccdf_activity_test is an unpopulated input flag in the CPS microdata (false for every unit), so nv_ccdp_activity_eligible is false everywhere. This is the same data-input artifact that affects sibling CCDF state programs (e.g. wv_child_care_subsidies is also $0 in microsim for the same reason). It is a known microdata input gap, not a formula bug. The full benefit pipeline — both regions, both provider types, all four age groups, all three copay tiers, both enrollment states, and the copay-waiver path — is verified through the unit and integration tests, which set meets_ccdf_activity_test: true (or is_homeless: true) and produce the expected non-zero benefits.

Verification TODO

• Confirm the per-day provider rates against an operational rate sheet (The Children's Cabinet / Las Vegas Urban League), as distinct from the CCDF State Plan base-rate table and the 2022 Market Rate Survey.
• Confirm the age-band month cutoffs (25 / 37 / 60-month boundaries, currently following the sibling CCAP convention) and the daily→monthly billing convention (21.67-day full-time-month proxy — Nevada does not publish an explicit conversion).
• Confirm the CC PT 06-25 effective-date label (Oct 1, 2025) against the 2024-10-01 parameter effective dates (the flat-copay structure took effect Oct 1, 2024).
• Confirm the 32.99% vs. 33% SMI copay boundary and the full MS 306 counted/excluded income source list.
• CI passes.

Test plan

• 101 unit + integration tests pass locally (policyengine-core test policyengine_us/tests/policy/baseline/gov/states/nv/dwss/ccdp/ -c policyengine_us -v).
• CI passes.
