We are excited to announce that the Call for tasks for IOI 2027 is officially open!

The scientific committee for IOI 2027 would love to invite everyone (except potential contestants) to submit their task proposals. If you know anyone who might be interested in creating tasks for IOI 2027, please share this announcement with them.

We welcome tasks of all difficulty levels, and we especially appreciate submissions of easy tasks. Original and creative easy tasks can be very challenging to create, and we always need more of them. We also welcome submissions across a variety of task types, including batch, communication, and output-only tasks as well as novel task types that have not appeared in IOI before.

You can submit your tasks through the following website, where you will also find more details about the submission requirements and the submission process: https://ioi2027.de/contest/call-for-tasks.

The deadline for the call for tasks is 31 December 2026, 23:59 UTC+14.

For any questions, please reach out to [email protected].
