How we measure, and what it cannot tell you.

We write short, plain-language assessments that help a person notice patterns in how they think, feel and work, and help an organisation understand the conditions its people work in. They are not clinical tests, they do not diagnose anything, and a result is a starting point for reflection rather than a verdict about who you are.

Two commitments run through everything: say only what the answers support, and protect the person answering. For individuals that means your results are yours. For organisations it means an employer sees group findings, never a person's answers.

The individual library has 100 assessments across 10 areas of life, 10 of them free. Each has 10 questions and takes three to five minutes. Questions describe everyday situations and ask how true they are for you, usually on a five-point scale; a few style assessments ask you to choose between descriptions instead.

Every assessment measures a small number of named dimensions, each made of a group of questions. Some questions are worded in reverse and scored the other way round, so that agreeing with everything does not produce a high score. A result reports the dimensions and an overall band, and the report explains what each dimension is and which end of it is the healthier one for this assessment.

The wording of every question, the scale, the scoring rules and the report text are versioned. Each saved result records the versions it was produced with, so a result can always be explained by the rules that made it, even after those rules change.

Alongside your answers we record how long each question was on screen. It is used only to judge how much weight a set of answers can carry; it is never shown to anyone else and never used to identify you.

The organisation programme measures 10 workplace dimensions with a 30-question Foundation Scan, then follows ten anchor questions through the year in shorter pulse rounds. Answers use a five-point agreement scale with a "not applicable" option, and are scored from 0 to 100.

Results are reported only for groups of at least 7 people, and a smaller group is combined with others rather than shown. Free-text comments are read by a person, stripped of anything identifying, and released only as themes. The workplace guide explains the year in full.

Each assessment is reviewed before publication for what it sets out to measure, for wording that could cause harm or be read as clinical, for whether people understand the questions, and for copyright and data protection. The records of those reviews are being compiled and will be linked from this page.

No Calmtree assessment has yet been validated through a pilot study. Validation needs response data: how answers spread, how consistently the questions in a dimension agree, whether results repeat over time. We will publish that work as it is done. Until then, scores describe your own answers. They are not compared with a population, and we do not describe them as percentiles or norms.

• A result reflects how you answered on one day. Mood, recent events and how generously you read yourself all move it.
• Self-report measures what you notice and are willing to say, not what someone else would observe.
• Nothing here is a diagnosis or a substitute for a doctor, psychologist or counsellor. If a result worries you, or something feels urgent, please speak to a qualified professional.
• Workplace findings describe groups, not individuals. They must not be used to make decisions about any one person's hiring, pay, promotion or employment.
• Example scores on this site, including sample reports, are illustrative and labelled as such.
