About IKO

An independent, global academic olympiad.

The International Knowledge Olympiad promotes excellence in education, critical thinking and international collaboration in Mathematics and English — identifying and nurturing academic talent, and encouraging intercultural exchange among students, educators and institutions.

Independent governance

Run by the IKO Academic Board — educators and subject experts who set the syllabus and approve every paper.

One official language

English is the official language for all communications and examinations, with translated papers where needed.

Held annually

A single set of unified standards, procedures and regulations applied the same way in every member country.

Open to every school

Any recognized school can take part through the official portal or a national Country Representative.

Two subjects, one standard

Rigorous, fair, and globally benchmarked.

Every paper is written by an international panel and scaled across regions, so a score means the same thing everywhere.
