Add Nevada Child Care and Development Program (CCDP)

[hua7450]

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.

Regulatory Authority

• CC PT 06-25 Annual Income Changes (eff. Oct 1, 2025) — current income chart and flat copay tiers. PDF (3 pages; intake chart p.2, renewal chart p.3)
• Child Care Policy Manual (July 1, 2024, MTL 01/24) — care-level age brackets (MS 631) and the base reimbursement-rate table (MS 633.2 Licensed Provider Daily Rates, 1-Star, p.107), plus activity/Purpose of Care categories (MS 400), residency (MS 218), child citizenship (MS 214), age limits (MS 210/211), income types (MS 306), deductions (MS 302), copay waivers (MS 163/181), and the $1M asset limit (MS 320). PDF (156 pages)
• FFY 2025-2027 CCDF State Plan (ACF-118) — two-tier SMI eligibility (§2.2.4 / §2.5.5) and the $1M asset limit; its per-day base-rate table (Tables 1-2, pp.54-56) corroborates the Manual MS 633.2 1-Star rates. PDF (296 pages)
• 2022 Child Care Market Rate Survey (eff. Apr 1, 2022) — 75th-percentile provider rates by region, provider type, and age, the survey basis for the published rates. PDF (92 pages)

Source-precedence caveat: The July 2024 Policy Manual's copay (MS 170/180) and income-eligibility sections are outdated — they still describe the pre-October-2024 sliding-scale copay (0-7% of income) and a single 85% SMI eligibility test. CC PT 06-25 explicitly supersedes these ("Subsidy eligibility remains at or below 41% of SMI for initial intake … and at or below 49% of SMI for renewal"; "The CCDP Policy Manual will be updated to reflect this change with the next manual release"). The Oct 2024 flat-copay change and the two-tier 41%/49% SMI eligibility are therefore authoritative; the Manual is used for the rules it did not supersede (rates, ages, citizenship, residency, income types, POC, waivers).

Manual verification (2026-06-21)

Verified the implementation page-by-page against the 156-page July 2024 Manual, cross-checked against the State Plan and CC PT 06-25.

Confirmed exact: child age < 13 (MS 210), special-needs age < 19 and its definition (MS 210/211), child-only citizenship with parent status not required (MS 214), Nevada residency (MS 218), care-level brackets 0/12/36/72 months (MS 631, "care level changes on the child's birthday"), subsidy = min(charge, state max) − family copay (MS 163), copay waivers limited to TANF/NEON + CPS/Foster + homeless (MS 163/181), and the $1M asset limit (MS 320). All 16 daily rates match the Manual MS 633.2 1-Star table (Clark + Washoe) and the State Plan Tables 1-2.

Income engine confirmed: PolicyEngine's federal hhs_smi for Nevada × 41%/49% reproduces the CC PT 06-25 income chart to the exact dollar for every household size (1-12); the copay bands break at 33% / 42% / 49% SMI.

Corrections made in this round:

• Clark center school-age daily rate $48 → $46 — the Manual MS 633.2 1-Star value (p.107). This is the only cell where the State Plan ($48) and the Manual (1-Star $46) differ; all other 15 rates match both. The rate tables now cite the Manual MS 633.2.
• Citation fixes: special-needs age now cites MS 210 (p.36, where "until age 19" appears); activity now cites MS 400 (p.76); asset limit cites Manual MS 320 (p.75); income-type codes corrected (tips are 306.48 not 306.43; disability insurance is 306.9; SSI is exempt in Nevada, 306.40).
• Documented as deferred: the MS 302.1 Average Cost of Care deduction and the foster/CPS household-of-one income exclusion (see Not Modeled).

Eligibility

Requirement	Source	How Modeled
Child under age 13	Manual MS 210	nv_ccdp_eligible_child: age < child_age_limit (13)
Special-needs child under age 19	Manual MS 210/211	nv_ccdp_eligible_child: where(has_developmental_delay | is_disabled, age < 19, age < 13)
Two-tier SMI income test	CCDF State Plan + CC PT 06-25	nv_ccdp_income_eligible: new applicants ≤41% SMI (smi_intake), enrolled families ≤49% SMI (smi_renewal), keyed off nv_ccdp_enrolled
Nevada residency	Manual MS 218	defined_for = StateCode.NV on the eligibility and output variables
Child U.S. citizen or eligible non-citizen (parent citizenship not required)	Manual MS 214	nv_ccdp_eligible_child reuses federal is_ccdf_immigration_eligible_child
$1,000,000 family asset limit	Manual MS 320; 45 CFR 98.20	nv_ccdp_eligible reuses federal is_ccdf_asset_eligible (gov.hhs.ccdf.asset_limit)
Qualifying activity (Purpose of Care 410-470)	Manual MS 400 series	nv_ccdp_activity_eligible: meets_ccdf_activity_test | is_tanf_enrolled | is_homeless | protective-care child (existing status hooks; no new POC enum input)

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; verified to reproduce the CC PT 06-25 thresholds to the dollar). 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. The per-day rate comes from the Manual MS 633.2 Licensed Provider 1-Star daily-rate table, keyed by 2 regions (Clark vs. all other counties, using the Washoe 1-Star rates as the lowest-percentile representative) × 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. (QRIS star tiers 2-5 and the lower Carson/Douglas and Rural area rates are not separately modeled — a conservative simplification documented in nv_ccdp_region.)
• Flat family copay (nv_ccdp_copay, keyed by % SMI): $0 (≤32.99% SMI), $90 (33% up to 42% SMI), $150 (above 42% up to 49% SMI). The $90/$150 break is at 42% (encoded 0.4201), confirmed from the CC PT 06-25 chart. 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.

Not Modeled

What	Source	Why
85% SMI mid-certification hard-exit protection	CCDF State Plan; 45 CFR 98.21(a)(1)(ii)	We don't track certification periods at the moment, so the mid-period protection is not simulatable; the operative enrolled ceiling modeled is 49% SMI.
Average Cost of Care deduction	Manual MS 302.1	Deferred — narrow child-only Kinship-Care / child-only-TANF / SSI-children population ($425/$398/$358/$209 by care level) we don't track at the moment. Documented in nv_ccdp_countable_income.
Foster/CPS household-of-one income exclusion	Manual MS 216.4.3.1 / 216.4.4.1	Nevada treats a foster/CPS child as a household of one with the traditional household's income not counted (served at 100% subsidy regardless of family income). It applies only to foster/CPS children, not all children. Their copay and need-for-care are already handled via the protective-care pathway; the income exclusion is documented as a limitation in nv_ccdp_income_eligible, not implemented.
Mid-certification continuity past age 13/19	Manual MS 210/211	No certification-period tracking at the moment.
Activity-hour verification and overlapping-schedule computation	Manual MS 400 series	We don't track activity-hour verification or per-parent schedules at the moment (administrative).
12-month certification period / continuity windows	Manual; federal CCDF	We don't track certification time windows at the moment.
Job-search 90-day/year limit + POC funding availability	Manual MS 430	We don't track per-category funding availability or job-search day counts at the moment.
Part-day / fractional-day rate adjustments and per-child fee ordering	Manual MS 641/654	We assume a full-time month; no part-day rule modeled.
Per-child copay waivers	Manual MS 163	Waiver applied at the whole-family level instead.

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

• Per-day rates verified against the Manual MS 633.2 1-Star table (p.107) and the State Plan Tables 1-2 (pp.54-56) — they match except Clark center school-age, where the Manual's $46 is now used.
• Age-band month cutoffs confirmed against Manual MS 631 (Infant 0-1 / Toddler 1-3 / Preschool 3-6 / School-Age 6-13 → 12/36/72-month cutoffs).
• Copay $0 floor confirmed at 33% SMI and the $90/$150 break at 42%; full MS 306 counted/exempt income list verified (SSI exempt in Nevada; tips fold into wages 306.48).
• Confirm the daily→monthly billing convention (21.67-day full-time-month proxy — Nevada publishes no explicit daily-to-monthly factor; MS 311 uses a weekly ×4.3 income factor, implying ~21.5 days).
• Optionally confirm rates against an operational rate sheet (The Children's Cabinet / Las Vegas Urban League), distinct from the Manual MS 633.2 table.
• CI passes.

Test plan

• 115 unit + integration tests pass locally (policyengine-core test policyengine_us/tests/policy/baseline/gov/states/nv/dwss/ccdp/ -c policyengine_us), including after merging upstream main.
• CI passes.
