Resumen

Georgia Milestones End-of-Course (EOC) assessment results for high-school core content areas, published for each of up to three administrations per school year (Winter mid-year retest, Spring primary, Full-Year aggregate) at the state, district/system, and school level. Core metrics are the count of students tested, the mean scale score, and the share of students at each of the four achievement levels (Beginning, Developing, Proficient, Distinguished Learner) plus the two cumulative shares. Literature subjects add a Reading Status split against a per-course Lexile threshold (9th Grade Literature 1050L through 2020; American Literature 1185L). Student Growth Percentile (SGP) metrics appear in the source layout from Spring 2024 but carry data only from the 2024-2025 school year (Algebra: Concepts & Connections and American Literature). Full-Year 2020-2021 uniquely includes enrolled_tested_rate, reflecting COVID-era participation drops.

Granularidad de fila: Una fila por year, district_code, school_code, administration, subject.

Métrica clave

avg_scale_score — Average Scale Score (score, 140–820)

Variables

Todas las columnas de la tabla de hechos. El código es el nombre exacto del campo que devuelve la API.

Columna	Tipo	Unidad	Rango	¿Nulo?	Descripción
`year`Year	integer	—	—	no	Ending calendar year of the school year (e.g., 2024 = school year 2023-2024). Winter administrations are stored under the school year they fall inside: Winter 2014 EOC is the 2014-2015 mid-year retest, stored as year=2015. Descripción completa▾ Ending calendar year of the school year (e.g., 2024 = school year 2023-2024). Winter administrations are stored under the school year they fall inside: Winter 2014 EOC is the 2014-2015 mid-year retest, stored as year=2015.
`district_code`District Code	string	—	—	yes	3-digit GOSA district/system code (FK to districts dimension). School-level rows for State/Commission Charter campuses use the 7-digit campus code (system 782/783 + school code) — 2015-2017 bronze published those rows under the bare system code and they are promoted here. NULL for state-level rows. Descripción completa▾ 3-digit GOSA district/system code (FK to districts dimension). School-level rows for State/Commission Charter campuses use the 7-digit campus code (system 782/783 + school code) — 2015-2017 bronze published those rows under the bare system code and they are promoted here. NULL for state-level rows. Se une a districts; agrega sus columnas de etiqueta.
`school_code`School Code	string	—	—	yes	4-digit GOSA school code (FK to schools dimension, composite with district_code). NULL for district- and state-level rows. Descripción completa▾ 4-digit GOSA school code (FK to schools dimension, composite with district_code). NULL for district- and state-level rows. Se une a schools; agrega sus columnas de etiqueta.
`administration`Administration	string	—	—	no	Which test window the row covers: winter retest, spring primary, or the full-year aggregate. Descripción completa▾ Which of the three publications a row comes from: winter = mid-year retest, spring = primary end-of-year administration, full_year = fall+winter+spring aggregate. The three slices are distinct cohorts, not duplicates. 3 valores permitidos▾ `winter` `spring` `full_year`
`subject`Subject	string	—	—	no	The high-school course tested (e.g. biology, us_history, american_literature_and_composition). Descripción completa▾ Snake-case EOC content area. The tested slate changed over time: 8-10 subjects through 2020 (incl. 9th Grade Literature, Physical Science, Economics, two algebra and two geometry courses); 5 standard subjects in 2021-2023 (gold year 2021 also carries the folded one-off Full-Year 2020-2021 8th-grade Physical Science administration as physical_science, so it shows 6 values); 3 in 2024 (american_literature_and_composition, biology, us_history — the 2024 Algebra: Concepts & Connections sheets are empty templates); and the 4-subject slate (adding algebra_concepts_and_connections) from 2025. 11 valores permitidos▾ `9th_grade_literature_and_composition` `algebra_concepts_and_connections` `algebra_i` `american_literature_and_composition` `analytic_geometry` `biology` `coordinate_algebra` `economics_business_free_enterprise` `geometry` `physical_science` `us_history`

`avg_scale_score`Average Scale Score	number	score	140–820	yes	Average end-of-course scale score (about 400-650 in practice); higher means stronger performance. Descripción completa▾ Mean scale score on the Georgia Milestones EOC scale. Reported scores span roughly 400-650; the contract enforces the full published EOC scale range of 140-820 (per-course bounds differ; Biology spans the full range per the GaDOE EOC Score Interpretation Guide). Preserved on its natural scale.
`scale_score_std_dev`Scale Score Std Dev	number	—	—	yes	Standard deviation of the scale scores — a dispersion measure, NOT a bounded score. Units are scale-score points; the value is always >= 0. Exempt from unit/range checks (it has no fixed upper bound). Published only by Spring 2015 system-level files, Winter 2021 files, and every file from Spring 2022 onward; NULL elsewhere.

Notas y limitaciones

Manejo de NULL

Las celdas suprimidas (muy pocos estudiantes para reportar) son NULL, nunca cero.
El cero es un valor real y reportado.

Limitaciones

Suppressed cells are NULL (not zero). State rows have NULL district_code and school_code. District rows have NULL school_code.
