The scoring process depends on whether you have taken a test of ability or a personality questionnaire.

With ability tests, your performance is compared with that of a large number of other people have taken same test previously.   For example, to know that you got 22 questions correct out of 30 doesn't actually tell you very much. Rather more interesting would be to know, for example, that only 5% of the large group of people who had taken the test previously had obtained a better score than this. In technical terms, we would say your score was "at the 95th percentile" – in other words, you have done as well or better than 95% of the other people who had taken the test previously. If you score was at the average level for the group, then we would say that you had scored at the 50th percentile – i.e. you have done as well or better than half of the group who had taken the test previously.

Generally speaking, an ability test report will explain your performance in such comparative terms and this will give you a basis for finding out how well you have done in comparison with other people.

Personality questionnaires and similar assessments are scored to give you a profile.  These assessments normally look at a number of different aspects of behaviour, preference or attitude, and together these aspects form your personal profile.  Some of these assessments may involve comparisons with groups who have previously taken the assessment, as with ability tests, whereas others will look at the relative importance to you of the different aspects assessed by the questionnaire.
