The admissions card measured 1503px on a live school page — half the height of every section put together, and nearly three times the next largest — with its default view rendering as four tiles adrift in about 1080px of blank card. The cause was a layout trick meeting content it was never sized for. The admissions views are stacked in one grid cell so switching them never shifts layout, and the hidden ones keep their box: only visibility is dropped. That works while the views are comparable. The distance view added in #102 carries a chart, a table and a map, came to 1402px against the tile grid's 316px, and pinned every other view to its height — including the one that renders by default, which nobody had clicked. Rather than only unpinning it, the detail moves out. Every other topic on the page is a section with a nav entry, and "how close did we need to live, and would we have got in?" is a topic, not a variant reading of the intake figures. The headline number stays on the Admissions tile where the intake story is; the record behind it now lives in a Distance section directly below. admissions 1503px -> 554px distance new -> 743px (median section on the page is ~528px) Three further changes, each of which also makes the content better rather than only shorter: * The map renders on request. Before a postcode is entered it is a circle drawn round a school, and it costs a Leaflet bundle and 240px to say so; a successful check opens it automatically, which is the point at which it starts answering something. Map height 320px -> 240px. * The chart appears only at the four published years that let the summary state a direction. Below that we already refuse to call the series a trend, and a line through three points asserts one regardless of what the sentence beneath it admits. The table carries those years anyway, with the reasons a line cannot show. * Three caveat paragraphs become one. They said walking-route twice and made the same point about priorities in two voices. It now sits in CutoffDistanceDetail rather than inside the check, so it still renders for a school with coordinates missing, where there is a table but no map and no check. The new e2e guard asserts no section exceeds 2.5x the median section height. Measuring the card's internals cannot catch this: the tile grid is flex: 1, so it absorbs the stretch and every box still looks full. The first version of this test targeted an arbitrary primary, passed against the live bug, and proved nothing; pointed at a school that actually holds cut-off history it fails on staging with "#admissions is 1459px against a 526px median".

Key Metrics (KS2)
The application tracks these Key Stage 2 performance indicators:
| Metric | Description |
|---|---|
| Reading Progress | Progress in reading from KS1 to KS2 |
| Writing Progress | Progress in writing from KS1 to KS2 |
| Maths Progress | Progress in maths from KS1 to KS2 |
| Reading Expected % | Percentage meeting expected standard in reading |
| Writing Expected % | Percentage meeting expected standard in writing |
| Maths Expected % | Percentage meeting expected standard in maths |
| Reading, Writing & Maths Combined % | Percentage meeting expected standard in all three subjects |
Quick Start
1. Clone and Setup
cd school_results
# Create virtual environment
python -m venv venv
source venv/bin/activate # On Windows: venv\Scripts\activate
# Install dependencies
pip install -r requirements.txt
2. Run the Application
# Start the server
python -m uvicorn backend.app:app --reload --port 8000
Then open http://localhost:8000 in your browser.
The app will run with sample data by default, showing 110 primary schools (66 in Wandsworth, 44 in Merton) with 5 years of KS2 performance data.
3. (Optional) Use Real Data
To use real UK school performance data:
-
Download Key Stage 2 data for the years you want (2019-2024)
- Select "Key Stage 2" as the data type
-
Place the CSV files in the
data/folder -
Restart the server - it will automatically load and filter to Wandsworth & Merton schools
Note: The app only displays schools in Wandsworth and Merton. Data from other areas will be filtered out.

Scheduled Jobs
Geocoding Schools (Cron Job)
School postcodes are geocoded by a scheduled job, not on-demand. This improves performance and reduces API calls.
Setup the cron job (runs weekly on Sunday at 2am):
# Edit crontab
crontab -e
# Add this line (adjust paths as needed):
0 2 * * 0 cd /path/to/school_compare && /path/to/venv/bin/python scripts/geocode_schools.py >> /var/log/geocode_schools.log 2>&1
Manual run:
# Geocode only schools missing coordinates
python scripts/geocode_schools.py
# Force re-geocode all schools
python scripts/geocode_schools.py --force
