An adaptive test built on Item Response Theory — the same psychometric standard behind TOEFL and IELTS. Fifty minutes, six skills measured independently, one certificate that holds up.
Each skill converges on its own ability estimate before the six are combined. You see exactly where your English is strong, and exactly where it is not.
Every answer moves your ability estimate. The next question is always chosen to tell us the most about where you actually are — so the test gets harder or easier in real time, never wasting your time on questions far from your level.
Your ability estimate (θ) starts at zero — roughly B1 — with wide uncertainty. The first questions are chosen to learn the most, the fastest.
Fifty adaptive items across the two skills bring your standard error down sharply. By this point your rough CEFR band is already visible.
Two receptive skills, tested independently, either confirm the estimate or reveal a meaningful gap between what you read and what you hear.
Based on your estimate so far, you receive a task at the right level of challenge — not a generic prompt every test-taker sees.
Six independent scores, one overall CEFR level, and a certificate with a verifiable ID — ready in minutes, not weeks.
Not just a letter grade. Every skill, scored on its own scale, so you and anyone reading it know exactly what to expect from your English.
IELTS and Cambridge cost $200–250 and take weeks. QEPTA costs less than dinner and returns a result before you've finished your coffee.
