Professor Hoot and the AI writing/speaking feedback are the only parts of Nest English that are not local. Before you turn them on, here is exactly what happens:

Four things you won't find together in any other free English test.
Most free tests just count your correct answers. This one runs a statistical model (Rasch) that re-estimates your ability after every answer, then serves the question that sits exactly at your level.
Every result comes with a ± margin and a reliability score for each skill. We don't know of another free English test that shows you the limits of its own accuracy.
Afterwards, review each question you missed and exactly why the right answer is right. A $65 test won't give you that.
No email. No account. No waiting, no ads. Your score, your full PDF report and your certificate are free and instant.

How the engine estimates your linguistic profile.
Solve grammar, vocabulary and reading questions that shift difficulty based on your answers.
Listen to a short passage and read a sentence aloud so the engine can estimate comprehension and fluency.
Download a PDF report mapping your composite score across CEFR and five international/regional indices.
Lightweight engineering built for a quick, honest estimate.
Each answer nudges the difficulty up or down, inspired by computer-adaptive testing concepts — a simplified version, not an official testing engine.
Uses your browser's built-in speech APIs for listening and speaking checks — no installs, no uploads. A typed fallback is offered if your browser doesn't support them.
Your answers, audio and history are processed and stored only inside your browser's local storage. Nothing is uploaded anywhere.
Transparency about the adaptive methodology and its limits.
A simple promote/demote ladder adjusts difficulty per answer. It is a simplified model, not a certified psychometric engine.
Your composite score is mapped to CEFR/IELTS/TOEFL-style ranges using publicly referenced comparison tables. Ranges are approximate and for guidance only.
Speech, answers and history stay in your browser whenever possible. Some browsers may use their own speech-recognition service, depending on browser and settings.
Everything you need to know about the adaptive assessment engine and speaking practice.
Take the adaptive diagnostic and get your five-skill English profile in about 15 minutes — free, private, and entirely in your browser.
The first four pages answer the most common free placement-test questions.
You have an unfinished test in progress.
The test ends as soon as your level is clear — usually around 25 questions.
Three short passages. Play each one up to twice, then answer two questions about it.
Read the sentence below aloud. If your browser can't listen, you can type it instead.
Transcribed by your browser's own speech engine. We store nothing.
This compares which words your browser recognized against the target — a word-match signal, not a native-pronunciation grade.

Nest English is completely free, requires no student accounts, and works on any device — making it ideal for classroom placement, homework, and self-study assignments.
Placement Test
Ask students to take the full assessment at the start of term to identify their level. No prep needed — the adaptive engine adjusts to each student automatically.
Progress Check
Assign a re-test at the end of each month. Students can download their PDF report and compare it to their first attempt to see genuine improvement.
Homework Assignment
Share the link below and ask students to complete the flashcard review or daily challenge. No account means nothing for IT to set up.
Mock Exam Practice
The Mock Exam mode simulates real test conditions: timed, fullscreen, no copy-paste. Great for building exam confidence before IELTS or TOEFL prep.
Copy the link below and share it via email, WhatsApp, or your learning management system.
An overview of the public scales we reference for comparison inside the engine.
Common European Framework — six bands from A1 to C2, widely used across Europe and beyond.
A 0-120 scale used mainly for academic admissions in North America and beyond.
A 0-9 band scale used for study, immigration and work across many countries.
A regional standardized English proficiency scale used by some national education systems.
A computer-based English test scored on a 10-90 scale.
An online English test scored from 10-160, accepted by a growing number of institutions.
Ranges shown are approximate public comparisons for self-guidance only and imply no official partnership with these test providers.
Most free English tests fall into one of two camps: short quizzes too brief to mean much, or longer tests that gate real feedback behind a sign-up form or a payment. We wanted something different — a genuinely adaptive diagnostic across five skills, with a report you can actually keep, that never asks for your email.
A simple adaptive ladder adjusts difficulty per answer across grammar, vocabulary, reading, listening and speaking, then maps your composite score onto public CEFR/IELTS/TOEFL-style ranges — clearly labeled as an estimate, never as a certified score.
Practice should respect your time and your privacy. No inflated stats, no fake testimonials, no data leaving your browser — just a tool that tells you, honestly, where you stand and what to practice next.
Professor Hoot is the wise little owl who guides the tour and keeps an eye on your streak. He never grades you, never judges a wrong answer, and — true to the species — is suspiciously alert if you happen to be studying between midnight and 4 AM.
Nest English is an independent project, built and maintained as a single self-contained file that runs entirely in your browser.
A few honest, practical reads about English testing and learning.

Real reading means holding an argument across paragraphs. Read at your natural pace, tap when you finish, then answer six questions. The text stays visible — this measures reading, not memory.

No black box. Here is exactly how the engine turns your answers into a level estimate — so you can judge the result for yourself.
Every question is tagged with one of six CEFR levels — A1, A2, B1, B2, C1 and C2. Answer correctly and the next question steps up a level; miss it and it steps down. This pinpoints your real level in fewer questions.
Each question carries a difficulty score based on its CEFR level. Your result is the ability level that best explains your actual pattern of right and wrong answers — a Maximum Likelihood estimate — so a single lucky guess or slip barely moves it.
Grammar, vocabulary, reading, listening and speaking are scored separately, then averaged into a single overall percentage. Skipping a module simply leaves it out of the average.
Your overall percentage is mapped onto publicly referenced CEFR bands and approximate IELTS/TOEFL ranges, shown in the table below.
A ± margin is estimated from how many questions you answered and how consistent your skills were. More questions and more even skills produce a tighter, more reliable range.
| Overall % | CEFR | IELTS | TOEFL iBT |
|---|---|---|---|
| 0–19 | A1 | 2.0–3.0 | 0–30 |
| 20–39 | A2 | 3.5–4.0 | 31–44 |
| 40–54 | B1 | 4.5–5.0 | 45–58 |
| 55–69 | B2 | 5.5–6.5 | 59–78 |
| 70–84 | C1 | 7.0–7.5 | 79–95 |
| 85–100 | C2 | 8.0–9.0 | 96–120 |
These mappings are approximate public comparisons for self-guidance only. Nest English is independent and not affiliated with Cambridge, IELTS, ETS/TOEFL or any official provider, and its estimate is not a certified score.
Privacy isn't a setting here — it's the architecture. Nest English is a single file that runs entirely on your device.
There is no backend. Your answers, score and report are generated locally and never leave your browser.
No email, no sign-up, no login. You can use every feature without identifying yourself.
No analytics, no third-party trackers, nothing sold to anyone. There are no ads in this tool.
We never record, store or upload your audio. But in Chrome and Edge the browser's own speech engine uploads your recording to Google to turn it into text. That is the browser doing it, not us — and we would rather tell you than hide it. You can skip the speaking module entirely.
Turning this off means puter.js is never even downloaded. Turning it on lets Professor Hoot and the AI feedback work — and sends what you write to Puter.
Your XP, streak, test history, flashcard progress and settings are kept in this browser's local storage so your progress survives between visits. Clearing your browser data — or using the button below — removes all of it permanently. Export a backup first if you want to keep it.
Every question you missed is saved here so you can learn from it. Stored only on this device.
