What Is HARNO?
HARNO (Haridus- ja Noorteamet — the Estonian Education and Youth Board) is the government agency responsible for administering official Estonian language proficiency exams. These exams are formally recognized by the Estonian government for all legal and administrative purposes, including residency applications, citizenship (naturalization), and employment.
Prior to 2020, the exams were administered by the Integration Foundation (Integratsiooni Sihtasutus). HARNO took over the mandate and has since updated the test formats to align with the Common European Framework of Reference (CEFR). The exams are available at A2, B1, B2, and C1 levels — each with distinct legal implications for expats living in Estonia.
Key fact: Estonia has one of the strictest language integration policies in the EU. Approximately 25-30% of Estonia's population is Russian-speaking, and language requirements affect hundreds of thousands of people. HARNO exams are not optional for long-term residents — they are a legal requirement for many categories of stay and work.

HARNO Exam Structure — All 4 Sections
Both A2 and B1 exams test the same four core skills, but with different complexity levels. Understanding exactly what each section requires is the foundation of effective preparation.
Kuulamine — Listening Comprehension
20-25% of total score
You listen to recorded dialogues, monologues, announcements, and conversations. Tasks include selecting the correct answer from multiple choice, filling in missing information, and matching statements to speakers. At A2, speech is slower and vocabulary is limited to everyday situations. At B1, conversations are at natural speed covering work, travel, social, and administrative topics.
How to prepare:
Listen to Estonian radio (ERR Vikerraadio), Estonian TV news (ETV), and podcasts. Use OpiFluent's voice conversations to build your ear for natural speech. Practice dictation — write what you hear, then check. HARNO publishes sample audio files on their website that closely mirror exam format.
Lugemine — Reading Comprehension
20-25% of total score
You read texts of increasing complexity — notices, short articles, instructions, informal messages, and newspaper extracts. Tasks include true/false/not stated questions, multiple choice, matching headings to paragraphs, and finding specific information. At B1, texts include formal language, administrative vocabulary, and nuanced opinion pieces.
How to prepare:
Read Postimees, Delfi, or ERR news in Estonian daily. Start with shorter articles and use vocabulary tools to look up unknown words. Build vocabulary systematically — OpiFluent's 1324 Estonian words across 22 topics covers the core CEFR vocabulary for A2-B1. Focus on administrative and formal vocabulary for B1.
Kirjutamine — Written Production
25-30% of total score
You produce written text: typically a semi-formal or formal letter, email, short article, or form-filling exercise. At A2, the task is a simple message or letter (80-120 words). At B1, you write a structured piece with clear paragraphs, appropriate register, and correct grammar — typically 150-200 words. Case endings and verb conjugation errors are penalized.
How to prepare:
Write short texts in Estonian every day and get them corrected — either by a tutor, a language exchange partner, or AI feedback. Learn the standard letter format in Estonian. Master the 14 grammatical cases — the writing section rewards accuracy. OpiFluent's chat feature lets you practice written responses with AI feedback.
Rääkimine — Speaking
25-30% of total score
The speaking section is conducted with a human examiner and consists of two parts: a monologue (1-2 minutes on a given topic) and an interactive dialogue (role-play or discussion with the examiner). At A2, topics are everyday situations: introducing yourself, describing your home or work, asking for information. At B1, you need to express opinions, compare options, and handle unexpected questions.
How to prepare:
This is where most candidates underperform — they study grammar but never actually speak. OpiFluent's AI voice conversations (VoiceChat mode) let you practice speaking Estonian for unlimited sessions, with the AI responding naturally and correcting your mistakes. Practice the speaking section format specifically: 2-minute monologues on topics like "My work," "My neighborhood," "Estonian culture."
Scoring and Pass Requirements
| Section | A2 Weight | B1 Weight | Min. Pass Score |
|---|---|---|---|
| Kuulamine (Listening) | 25% | 25% | 60% |
| Lugemine (Reading) | 25% | 25% | 60% |
| Kirjutamine (Writing) | 25% | 25% | 60% |
| Rääkimine (Speaking) | 25% | 25% | 60% |
| Overall pass threshold | — | — | 60% each section |
Critical: You must pass each section individually with at least 60%. Failing even one section means failing the entire exam — regardless of your scores in the other three. Many candidates pass listening, reading, and writing but fail speaking. Prioritize speaking practice.
How OpiFluent ExamSim Prepares You
OpiFluent includes a dedicated ExamSim (Exam Simulator) feature built specifically for the HARNO A2 and B1 exam format. Here is what it includes:
Kuulamine (Listening) simulation
AI-generated audio dialogues in Estonian at the appropriate speed and vocabulary level for A2 or B1. Multiple-choice comprehension questions mirror the real exam format. The AI can adjust difficulty based on your performance.
Lugemine (Reading) simulation
Reading passages from everyday contexts: notices, letters, short news articles, administrative texts. Questions test both global comprehension and specific detail retrieval — exactly as in the real HARNO exam.
Kirjutamine (Writing) practice
Prompted writing exercises with AI evaluation. Write a letter to a neighbor about a noise problem, an email to your employer requesting time off, or a short description of your neighborhood. The AI identifies grammar and case errors.
Rääkimine (Speaking) simulation
This is the most valuable feature. OpiFluent's voice AI simulates the speaking section: you give a 2-minute monologue on a given topic, then engage in a dialogue. The AI plays the examiner role and provides feedback on fluency, vocabulary range, and grammatical accuracy.

Frequently Asked Questions
How do I register for the HARNO exam?
Registration is handled through the HARNO website at harno.ee. You create an account, select your exam level (A2 or B1), choose a test date and location (Tallinn, Tartu, Narva, and other cities), and pay the exam fee. The fee is currently €60-80 depending on the level. Bring your ID document to the exam — the same ID used during registration.
Can I take the HARNO exam online?
As of 2026, the HARNO language proficiency exams must be taken in person at a certified testing center. The speaking section requires a physical examiner. Some preparatory courses and mock exams are available online, but the official exam itself requires in-person attendance.
What happens if I fail one section of the HARNO exam?
If you fail one or more sections, you must retake the failed sections. You do not need to retake sections you passed. There is a minimum waiting period of 3 months between attempts for the same section. Section results are valid for 2 years — you can pass sections in different exam sessions and combine them for overall certification.
How is the speaking section evaluated?
The speaking section is evaluated by a trained HARNO examiner using a standardized rubric covering: range of vocabulary, grammatical accuracy, fluency and coherence, pronunciation and intelligibility, and task completion. You are not expected to be perfect — the evaluator is assessing overall communicative competence, not zero-error performance. Being understood and maintaining conversation is more important than avoiding all mistakes.
Do I need the HARNO exam for EU citizenship?
The HARNO exam is required specifically for Estonian citizenship (naturalization) at B1 level. EU citizens residing in Estonia are not required to pass the language exam for residency, but they may need it for employment in certain roles. Non-EU nationals typically need A2 for long-term residency and B1 for naturalization.
