DNV-certified (EFPA)

Built on Jung's typology
Over a century of psychological research
Used in HR, leadership and coaching
Across real organisations every day
One assessment, fifteen ways to read your team.
Every team report opens with the Team Compass — eight roles on one wheel — and goes deep on communication, conflict, stress, leadership, decision-making and the pairs that make or break collaboration.
Every report includes fifteen analysis lenses:
Reports update automatically as the team changes — plus an insights tab where an AI assistant, grounded in your team's actual results, answers follow-up questions.
Lead each person the way they want to be led.
JTI gives leaders, HR partners and coaches a shared vocabulary for how different people think, decide, and respond to pressure.
Compose better teams
See where your team has range, where it's narrow, and which conversations to start before tensions appear.
Speak to who is listening
Adapt your message to how each person prefers to take in information and make decisions.
Defuse conflict early
Most team conflict comes down to type difference, not personality. The reports name the patterns and what to do about them.
The four type dimensions
Become more of who you already are.
Type isn't a box you fit into. It's a description of preferences you already have, written down in a way you can work with.
Self-awareness, plainly described
Your preferences for taking in information and making decisions, in language you'd use yourself.
Your less-developed sides
The parts of you that are quieter than the rest, and how to bring them on as you need them.
A direction, not a label
Use your type as a starting point for the next decision or conversation. It's not a fixed verdict, and it can develop with you.
Reports people actually read.
Every participant gets a long-form description of their type — strengths, growth areas, communication style, stress patterns — on screen, as a PDF, and as booklets you can put on the table in a workshop.
Deliver JTI in your organisation.

What makes JTI different
There is no shortage of type indicators. JTI has been independently reviewed against a European test standard and stays close to Jung's original work.
Independently reviewed
Certified by DNV against the EFPA Test Review Model, the European psychologists' standard for evaluating tests (Norwegian version, for development use). First certified 2017; the current certificate is valid until 2028.
Grounded in Jung's original typology
Built on Carl Jung's original typology, with the language modernised for today.
A complete practitioner toolkit
Assessment, reports, team analysis, booklets and certification live in one platform — from a single debrief to a full team programme.

“For 20 years I've used JTI in my career-change programmes, and over 11,000 people have found their right path. The most powerful moment is when someone realises they hadn't been failing because they weren't capable enough — but because the work didn't match their natural preferences.”
