Panini Linguistics Olympiad 2022


The Panini Linguistics Olympiad is the Indian national program for selection and training of the candidates who represent India at the International Linguistics Olympiad (IOL).

The program is coordinated by Microsoft Research Labs India, International Institute of Information Technology Hyderabad, JNU Delhi and the University of Mumbai & is actively supported by regional coordinators across the country including Chennai Mathematical Institute, IIT Guwahati, SNLTR Kolkata, and IIT Patna.


Round 1

It is a national level test which typically comprises of about 5-6 problems to be solved in 4 hrs.

These problems are all self-contained, i.e. unlike other competitions, all the data you need to crack the whole thing, is in the problem itself, thus, you are expected to sharpen logic and develop your own techniques to solve problems from languages all over the world and uncover new features, that you might not have thought of before.


Round 2

Is typically a 7 to 10 day camp, for the top 25-30 seniors and 5-10 juniors selected in that year

It was hosted by Microsoft Research Lab, Bangalore till 2015, after which International Institute of Information Technology, Hyderabad took over.

In between this week of fun, contestants compete in a mid test and an end test which determine wether they are selected to participate in the IOL International Linguistics Olympiad.



If you are studying in grade 6, 7, or 8, you are eligible to appear for the Junior contest.

If you are studying in grade 9, 10, 11, or 12, you are eligible to appear for the Senior contest.

However, if you have attended the Invitational Round Camp in any previous year, you can appear only in the Senior contest.
