A speaking diagnostic for English speakers learning Japanese.
ii-5 is built around one belief: speaking proficiency is what most learners need to know about themselves, and almost nothing else measures it precisely. We do.
How ii-5 thinks about assessment.
- 01
Speaking-first
We measure what comes out of your mouth, not what you can recognize on a page. Pronunciation, grammar under pressure, register choice — the things that actually matter in conversation.
- 02
AI grading, human review
Every submission runs through a calibrated AI pipeline, then a certified grader reviews and finalizes. You get the speed of AI with the trust of human judgment.
- 03
Five dimensions, scored separately
A single score hides where you actually need work. ii-5 returns a per-dimension profile so the next step is obvious.
