Resumen

Georgia Milestones End-of-Grade (EOG) assessment results for grades 3-8 — published annually (except 2020, cancelled due to COVID) at the state, district/system, and school level. The primary 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. English Language Arts rows additionally carry Reading Status metrics (pct_below_grade_level_lexile / pct_grade_level_or_above_lexile) from 2018 onward, anchored to grade-specific Lexile thresholds (520L for grade 3, 740L for grade 4, 830L for grade 5, 925L for grade 6, 970L for grade 7, 1010L for grade 8). 2016-2021 grade 6-8 rows split affected subjects into EOG / EOC / Combined variants to represent middle-schoolers taking end-of-course exams early (captured in the assessment_type column). 2022+ drops the EOC variants (moved to the georgia_milestones_end_of_course topic), adds a Standard Deviation metric per subject, and adds Physical Science for grade 8. 2024-2025 adds Student Growth Percentile (SGP) metrics — num_sgp_received, sgp_median, pct_sgp_low_growth, pct_sgp_typical_growth, pct_sgp_high_growth — reported on the parent ELA / Mathematics rows for grades 4-8.

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., 2025 = school year 2024-2025). 2020 is absent — the COVID-19 pandemic cancelled the administration. Descripción completa▾ Ending calendar year of the school year (e.g., 2025 = school year 2024-2025). 2020 is absent — the COVID-19 pandemic cancelled the administration.
`district_code`District Code	string	—	—	yes	3-digit GOSA district/system code (FK to districts dimension). 7-digit charter / state-school campus codes are preserved in full; 2015 school-level rows published under the bare charter SYSTEM codes 782/783 are promoted to the 7-digit campus code (system + school code), and the 2015 shared state-school code 799 is remapped to the unique 7991893/7991894/7991895 codes used from 2016. NULL for state-level rows. Descripción completa▾ 3-digit GOSA district/system code (FK to districts dimension). 7-digit charter / state-school campus codes are preserved in full; 2015 school-level rows published under the bare charter SYSTEM codes 782/783 are promoted to the 7-digit campus code (system + school code), and the 2015 shared state-school code 799 is remapped to the unique 7991893/7991894/7991895 codes used from 2016. 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.
`grade_level`Grade Level	string	—	—	no	Tested grade, 03 through 08 (Milestones EOG covers only grades 3-8). Descripción completa▾ Grade level, zero-padded 2-char string ('03'..'08'). Georgia Milestones EOG is administered only to grades 3-8. Same encoding as the other per-grade education topics. 6 valores permitidos▾ `03` `04` `05` `06` `07` `08`
`subject`Subject	string	—	—	no	The content area tested (english_language_arts, mathematics, science, social_studies, physical_science). Descripción completa▾ Snake-case academic content area: english_language_arts, mathematics, science, social_studies, physical_science (grade 8 only, from 2022 — 8th-graders taking the high-school Physical Science course early; bronze labels it 'HS Physical Science'). Bronze ships Reading Status and Student Growth Percentile (SGP) as parallel "subject" blocks, but those are metric families computed on the ELA / Mathematics test-taker population — the transform folds their metric columns onto the parent ELA / Mathematics row (pct_below_grade_level_lexile, pct_grade_level_or_above_lexile, num_sgp_received, sgp_median, pct_sgp_*) and drops the parallel rows. 5 valores permitidos▾ `english_language_arts` `mathematics` `science` `social_studies` `physical_science`
`assessment_type`Assessment Type	string	—	—	no	Marks regular EOG vs the 2016-2021 early end-of-course variants; use eog for year-over-year comparisons. Descripción completa▾ Differentiates regular EOG from the middle-school EOG / EOC / Combined triples that existed in 2016-2021 (middle-schoolers taking End-of-Course exams early: Mathematics 2016-2019, Science 2016-2021, English Language Arts 2018-2019 — never Social Studies). 2015 and 2022+ data is always `eog`. Filter assessment_type = 'eog' for the canonical comparison-safe year-over-year EOG-only time series. 3 valores permitidos▾ `eog` `eoc` `eog_and_eoc_combined`
`num_tested`Number Tested	integer	count	—	yes	Number of students who took the test. NULL when the source suppresses the cell ('--') for small populations. Descripción completa▾ Number of students who took the test. NULL when the source suppresses the cell ('--') for small populations.
`avg_scale_score`Average Scale Score	number	score	140–830	yes	Average end-of-grade scale score (140-830 scale); higher means stronger performance. Descripción completa▾ Mean scale score on the EOG scale. Georgia Milestones EOG scale scores span 140-830 across grades/subjects (per-grade min/max differ; the envelope runs from the grade-6 ELA floor of 140 to the grade-3 ELA ceiling of 830, per the GaDOE EOG Score Interpretation Guide); the contract enforces that range. NOT converted to 0-1 — scale scores are preserved as-is per education CLAUDE.md. Never published for eoc / eog_and_eoc_combined rows (the bronze EOC blocks ship no Mean Scale Score column).
`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 from 2022 onward; NULL for all earlier years.

`pct_below_grade_level_lexile`Percent Below Grade Level Lexile	number	proportion	—	yes	Reading Status: share of ELA test takers reading BELOW the grade-specific Lexile threshold (2018 onward).

The threshold is 520L / 740L / 830L / 925L / 970L / 1010L for grades 3 / 4 / 5 / 6 / 7 / 8 — documented here rather than encoded in the column name so the schema stays grade-agnostic.

`enrolled_tested_rate`Enrolled Tested Rate	number	proportion	—	yes	Share of enrolled students who actually tested. Published ONLY by the 2021 files (testing was optional during COVID, so participation is essential context); NULL for every other year. The 2021 grade-8 system file leaves this sub-header blank in the ELA-EOG block (a merged-cell artifact); the transform repairs the header so the published participation rates are preserved.

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.
