The Judgement Index assessment
A unique online assessment that measures value-based behaviours and judgement capacity.

Scientifically validated – Mathematically proven
The Judgement Index is used globally to support and identify:

Recruitment + Retention

Leadership + Team Development

Risk, Safety + Compliance

Wellbeing Issues + Stress
The assessment
Unlike anything you’ve experienced before
With two sets of 18 abstract statements to order, and taking, on average, just 15 minutes to complete, the Judgement Index is a simple assessment for participants.
Because of the abstract nature of the phrases, the assessment forces the participant to reflect and sieve through their own value systems before deciding on an order, which is why it is not possible to predict a desired order and sequence or outcome.
What it measures
Going far beyond personality
The assessment empowers you to measure the value system and the judgement capacity and capability of an individual, and it does so with unswerving accuracy.
There are over 12 trillion possible outcomes from the Judgement Index and results can be shown for over 60 different indicators, looking at the participants work and self (personal) side, their internal, external and big picture values, along with their balance of values.
The reports
One assessment with many report options
From individual, sector or role specific reports, to leadership reports, to group and team reports, we can advise the best option for your needs.
The difference between The Judgement Index and personality assessments
People can have pleasing and engaging personalities. They may even have the skill sets, experience, and knowledge your organisation requires. Studies have shown that people are more likely to hire someone they feel is “like them” and we often hear people say they recruit on “gut instinct”
However, if the candidate does not possess good judgement – the determining factor in how every other talent and capability they offer is utilised – then successful outcomes are often not realised.
Personality assessments often categorise people into one of sixteen personality types.
In fact, someone who is a CEO and a particular personality type will no doubt find others with the same type serving life in prison. The differentiator between these people, one in prison and one regarded as a success is their judgement. Personality simple is not a good predictor of success – good judgement is.
The Science
From the value-science of Axiology
The Judgement Index is based on the work from Nobel Prize nominee Dr Robert S. Hartman, who was highly regarded as the father of modern Axiology.
Axiology is a value-science that looks at what and how we value. This can determine our strengths and development areas as we tend to focus more closely on the things that we value.
The Judgement Index team are proud professional members of the Robert S. Hartman Institute and are committed to their continued learning in Axiology
