Eligibility

Requirement	Source	How Modeled
Child under 13 (or 19 if disabled)	State Plan §2.2.1 (p. 20)	al_ccsp_eligible_child
Initial income ≤ 180% FPL	State Plan §2.2.4 (p. 24)	al_ccsp_income_eligible with al_ccsp_enrolled = False

Hard cap ≤ 85% SMI	45 CFR 98.20 + State Plan §2.5.2 (pp. 24, 35-39)	al_ccsp_income_eligible
Asset limit ≤ $1,000,000	State Plan §2.2.6 (p. 27)	is_ccdf_asset_eligible (federal CCDF helper, reused)
Activity ≥ 15 hrs/week	State Plan §2.2.2 (pp. 21-23)	al_ccsp_activity_eligible
Immigration	45 CFR 98	is_ccdf_immigration_eligible_child (federal CCDF helper, reused)

Alabama residency	State Plan §2.2 (p. 20)	defined_for = StateCode.AL

Family unit ≈ SPMUnit (PE's SPMUnit may include unrelated cohabitants that AL excludes; documented as known approximation).

Income Calculation

• Gross monthly income — no deductions ("Regulations allow for no deductions to gross income" — Fact Sheet)
• Counted sources: see income/countable_income/sources.yaml (employment, self-employment, farm operations, SS, pensions, unemployment, workers' comp, TANF, SSI, state supplement, interest, dividends, alimony, veterans' benefits)
• Excluded: child support received, spousal support received, room rent
• Weekly→monthly multiplier: 4.333 (regulatory literal per Fact Sheet, NOT WEEKS_IN_YEAR/MONTHS_IN_YEAR — per CT C4K precedent)

Family Fee (Copay)

Weekly per-child fee, sliding scale by FPL band. Effective Jan 1, 2024.

Initial tier (9 bands, 0-180% FPL):

FPL band	Fee/week/child
≤100%	$0
101-110%	$18
111-120%	$21
121-130%	$24
131-140%	$27
141-150%	$30
151-160%	$33
161-170%	$36
171-180%	$39

Continuing tier (181-200% FPL):

FPL band	Fee/week/child
181-190%	$42
191-200%	$45

Copay waivers (REQ-021/022/023/024):

• ≤100% FPL (encoded in fee table $0 band)
• Family with disabled child (§3.3.1(iv))
• Head Start / EHS enrollment (§3.3.1(v))
• Foster care / protective services (§3.3.1(vi))

NOT waived: homeless families (homelessness only waives the eligibility test via the protective-services pathway, not the copay — per §2.2.2(f) and §3.3.1(iii)).

Provider Rates

486-cell rate matrix transcribed verbatim from Provider Rate Chart:

• Provider types: Center, GFDC (Group Family Day Care), FDC (Family Day Care), INFORMAL (flat $40/wk cap)
• Regions: 9 (Huntsville, Tuscaloosa, Mobile, Ft Payne, Birmingham, Talladega, Montgomery, Dothan, Opelika)
• Age categories: Infant/Toddler (<36mo), Preschool (36-60mo), School-Age (≥60mo)
• Quality tiers: Base + STAR 1-5 (~2% over Base per STAR; transcribed cell-by-cell, NOT derived — published rates show rounding inconsistencies)
• Part-time (≤25 hrs/wk): ½ × full-time rate
• County → region lookup masked by state_code_str == "AL" (per WA-PTE lesson) to prevent non-AL households crashing on missing keys

Benefit Calculation

Per-child weekly subsidy = max(0, min(provider charge, max weekly rate) − per-child copay).

Per-child monthly subsidy = weekly subsidy × 4.333 × al_ccsp_eligible_child.

Family-level copay split equally across eligible children. SPMUnit benefit = sum of per-child monthly subsidies.

Coverage

28 in-scope requirements / 28 implemented (100%). 9 NOT-MODELED items documented as known limitations.

Not Modeled

• 7% federal copay cap (45 CFR 98.45) — State Plan §3.1.1 acknowledges family total may exceed 7%; fee table is source of truth
• EHS-CCP as distinct from Head Start (proxied via is_enrolled_in_head_start)
• TANF-Other Relative and Special Needs protective-service eligibility categories
• Granular job-training / GED / internship enrollment status
• Irregular / temporary income exclusion (§2.2.5)
• McKinney-Vento homelessness flag (uses is_homeless Household variable instead)
• CMA discretion / outreach / intake operations (§2.4, §2.5.3)
• Job-search-alone activity
• Priority / waitlist categories (§2.3)
• 12-month continuity / mid-period income changes (§2.5.2)
• Kinship care EXCLUDED from protective services per §2.2.2(f) (informational, not a modeling gap — §3.3.1(vi)'s "kinship care" phrasing treated as descriptive of the federal CCDF list, not AL-specific inclusion)

Test plan

• 103 tests pass locally
• make format clean
• CI passes
• Regulatory reviewer verifies: disabled-parent activity exemption (not in §2.2.2 text but standard cross-state convention per SC/VA), 7% copay cap omission, protective-services member coverage

Verification TODO

• Confirm Provider Rate Chart effective date (chart is undated on its face; defaulted to 2024-01-01)
• Confirm Provider Rate Chart hosting on alacourt.gov is the current/canonical version
