The application takes real work, by our reading.
1. What to get ready
It asks for something outside the usual documents; read it below.
In their words: “A CSV of coverage gap scores for each census tract, uploaded on the Zindi challenge page, with a methodology writeup that is used to judge the two special prizes. Top 10 finishers must send their code within 48 hours of being asked.”
2. Dates
- Closes 31 October 2026, in 9 days.
- Aim to send it by 28 October 2026. Websites slow down near a deadline, and data runs out. Our advice
Download checklist (.txt) Send to WhatsApp
The download is a small text file. You can read it later without data. It also lists each condition they set, so you can tick yourself against them. WhatsApp sends the same list to you, or to somebody helping you.

Tips for applying for a competition
General advice from us, the same for every competition. It is not what this organisation says; that is above.
- Read the rules and the judging criteria first, and write to them.
- Check who owns your work after you enter. The rules usually say.
- Submit a day early. Upload pages are often slow near a deadline.
If there is an interview or a test
- If there is a final or a pitch, practise out loud and time yourself.
All our tips and messages to copy. Practise answering, with nothing kept. Received an offer? Check whether it is real, then read before you say yes.
