Assessment
to international standards

We are the team of ISTOK — the Center for Applied Linguistic Research and Testing at MIPT. We make language assessment objective and convenient: no extra barriers, fast results, and the option to test from anywhere in the world.

Mission

A new generation of possibilities

Our mission is to make modern language diagnostics and learning accessible to everyone: a result you can trust, a process without undue stress that helps you move forward with confidence. ISTOK helps you not only learn your level, but find a starting point, confirm your language skills with an official certificate, and get recommendations for further development.

Adaptive difficulty — items adjust to the test taker's current level
Clear result — the CEFR assessment method, not one opaque score
Detailed results — thorough comments on errors available on request
Accessibility — no offline centres, no long wait for results
Offline format — we'll help set up your own testing centre at your university or company to international standards
Expertise — we've run over 20,000 ISTOK language tests at Russian universities

Who's behind this

The MIPT team and partners

The platform is built on an interdisciplinary approach. We've brought together professionals from different fields: language didactics, machine learning, mathematical statistics, corpus and psycholinguistics, neurolinguistics and social psychology. AI helps process results and reduce subjectivity, while the scientific foundation ensures the reliability and validity of the assessment.

Methodology

How we assess

CEFR

Our scale follows the European CEFR standard — the result is unified and makes sense to any teacher.

Adaptive algorithm

The test rebuilds in real time, adapting questions to each user's level. Item difficulty is determined with AI — this shortens testing time and builds an individual trajectory.

The role of AI

Written responses and speaking are graded by an artificial-intelligence language model.

Process transparency

ISTOK uses proctoring — a modern system for monitoring the test process via video recording.
