Georgia Alternate Assessment (GAA) achievement-level results for Georgia public school students with significant cognitive disabilities, published by the Governor's Office of Student Achievement (GOSA). The GAA is a separate assessment from Georgia Milestones, taken by students whose IEP team determines they cannot access the general assessment. A tidy achievement-level fact per (entity x demographic subgroup x subject) with counts and percentages at up to four achievement levels plus two derived cumulative shares. 2011-2018 is the portfolio-based 3-tier GAA 1.0 (no distinguished tier — those metrics are NULL, not 0); the Milestones-aligned 4-tier GAA 2.0 begins in 2019. Coverage: 2011-2019, 2022-2024 (2020-2021 COVID testing suspensions). The source also publishes a 2004-2007 participation-only summary; that different measure family (participation, not achievement) is intentionally excluded from this table.

**Filterable categorical columns** (comma-separated values union; multiple columns AND together):
- `subject` — one of: `english_language_arts`, `mathematics`, `science`, `social_studies`

**Detail levels available:** districts, schools, states (default: `schools`)

**Year coverage:** 2011–2024 (no data for: 2020, 2021)

**NULL handling:** suppressed cells are NULL (not zero); zero is a real value.

**Source:** Governor's Office of Student Achievement (GOSA)
