I recommend you take the questionnaire two or three times. This is because the model attempts to represent something that is in constant flux:your personality. Each time, you should find that your responses, while maybe different in terms of the actual four-letter code returned, are broadly similar when it comes to which aspects are emphasized.

APT, the Association for Psychological Type, reports that it is normal for any one individual's responses to vary by up to 25 percent at different times.

Think of the result not as a fixed defining quantity, but as a representation of the relative strengths of various motivators upon you.

How to take the Questionnaire

There are only twenty questions so it's worth really pondering on the answers, allowing your inner sense to come into play as well as your immediate reaction.

In each case, you have to choose your preference, and its strength, by selecting a point between two, not necessarily related, statements. Click on the button that most closely represents you.

What the test is trying to gauge is the relative strength of internal motivators, so expect to be challenged. Your preference can range from marginal (in the center) to emphatic (at the ends).

If you omit an answer, the test will distort your result in an unpredictable way.

When you've answered all the questions, click on the "Submit" button.
