The short version
A shared instrument for measuring Jesus-following, given away for free.
About seven minutes. Run under your own organisation's name, telling you where your people actually are on the journey — and, because hundreds of other organisations run the same shared instrument, how that compares to your country and the world.
What it measures
Three questions × four tiers.
Three questions — what we measure: do they follow Jesus, do they participate in his mission, does their world look different. Four tiers — how deep it has gone: exposure, response, formation, multiplication.
Every item in the survey carries exactly one question and one tier. Read across a row to see how far one question has travelled; read down a column to see what a whole group has and has not yet reached. The narrowing between columns is the diagnosis.

How someone moves through it
Nobody is asked to answer as something they are not.
One opening question sorts a respondent onto one of two honest tracks — already following Jesus, or not yet. From there both tracks are asked across the same four tiers, worded for where they actually are, so the depth of the journey is always measured the same way.
Someone exploring never contributes to the official Index — their answers feed a separate Exploration Index instead, kept apart from it entirely. At the end, anyone willing can add a few optional questions about their own journey.

Yours, under your name
Your logo, your colour, your consent process. To a young person it is their youth group asking — because it is.
Anonymous, always
No name, no email, no precise location, no birthdate. Consent — including parental consent — is handled by you, locally.
Free, permanently
Running the Index costs nothing, and it stays that way. Your standard report is included.

The one claim it ever makes
“Of those who have completed the Index — here are the results, and here is how you compare.”
Every score carries its sample size. No benchmark appears for a country until enough people there have completed the Index. No organisation ever sees another's results, and no organisation ever sees an individual response — not even its own respondents'.
