File: `data/nba_draft_hs_panel.csv`
Unit of observation: one drafted player-pick (typically 60 per draft year).
## Columns
| Column | Type | Description |
| --- | --- | --- |
| `draft_year` | int | NBA draft year (2016–2026 in this release). |
| `pick` | int | Overall pick number (1–60 typical). |
| `round` | int | 1 if pick ≤ 30, else 2. |
| `player_name` | string | Player name as in source. |
| `nba_team` | string | Drafting franchise abbreviation (Basketball-Reference). Empty for curated 2026 if not yet joined to a team table. |
| `college_or_prior` | string | College, G League, or international club / pathway listed as prior stop. |
| `high_school_finish` | string | **Finishing** secondary school / academy (last U.S. HS or prep program competed for). Empty if unknown or no U.S. HS. |
| `hs_city` | string | City/town of finishing school when available. |
| `hs_state` | string | U.S. state (name or postal abbr) or `intl` / non-U.S. label. |
| `school_type` | enum | See definitions below. |
| `school_type_method` | enum | How `school_type` was assigned (see below). |
| `ambiguity_flag` | string | Non-empty when classification is contested or pending review. |
| `notes` | string | Free-text caveats, prior schools, tuition citations (curated rows). |
| `place_median_hh_income` | number or empty | ACS 2024 5-year median household income for HS city/place (public rows; see `data/public_hs_town_income.csv`). Ecological town proxy — not family income. |

| `hs_source` | string | Provenance of HS attribution. |
| `bbref_player_url` | string | Basketball-Reference player URL when scraped. |
## `school_type` definitions
Mutually exclusive finishing-school buckets (same rules as the 2026 case study):
| Value | Meaning |
| --- | --- |
| `public` | U.S. public district or public magnet high school. |
| `local_private` | Catholic / Episcopal / Christian / independent **day** school that is **not** a national boarding / prep magnet. |
| `elite_prep` | National boarding prep, postgraduate academy, or alternative academy pathway used as finishing school (e.g. Link, IMG, Montverde, Oak Hill, Brewster, Wasatch, Overtime Elite, Sunrise Christian, Compass Prep). |
| `international` | No U.S. high school finish (overseas club / federation / academy pathway). |
| `unknown` | U.S. finishing school named (or missing) but **not** yet hand-reviewed for public vs local private; **or** HS attribution missing. |
**Do not treat `unknown` as a substantive pathway category in papers** — it is a data-quality status.
## `school_type_method`
| Value | Meaning |
| --- | --- |
| `curated_hand` | Human-reviewed (2026 case study). May include `public` / `local_private`. |
| `curated_override_csv` | Matched `sources/curated_overrides/school_type_overrides.csv` (name+state; web-sourced). |
| `auto_international_no_us_hs` | No U.S. HS on source and/or clear overseas pathway. |
| `auto_elite_prep_dictionary` | Finishing name matched curated elite-prep dictionary (`scripts/classify_school_type.py`). |
| `pending_public_private_review` | U.S. HS present; public vs local_private not assigned. |
| `missing_hs_attribution` | No finishing school string available. |
## Important measurement notes
1. **Finishing school, not birthplace or first HS.** Prior stops (e.g. public → Link Academy) do not change the bucket.
2. **No invented schools or types.** If sources disagree, keep the BBRef/curated finishing name and flag ambiguity.
3. **Income columns are optional** and currently sparse (2026 public-HS towns only).
4. **2026 coverage** may reflect a hand-built first-round-scale slate from the case study; confirm against the official NBA draft board when locking a paper sample.
