• Finds the level fast.Like ASER, the test starts in the middle — at two-digit addition — and moves up or down the Vana ladder until it finds the last skill the child can truly do. It stops the moment the level is found.
• Covers the spine of numeracy.From reading a one-digit number to division — the skills everything else stands on.
• The child does it alone.Every question is read aloud in Hindi. No hints, no ticks, no red crosses — the child never sees a "wrong". Two questions at each step, and a split always earns a third, so one slip is never a verdict.
• Two reports.A one-page report for the parent, in Hindi. A benchmark report for your organisation: each child's true level, set against the NIPUN Bharat expectation for her class, and how far she moved during your programme.

An adult hands the phone over and stays nearby — one adult can run ten phones at once — but no one helps with the maths.
