Ipsative tests are based on forced choice questions and responses. Each choice is scored. These scores can only represent the relative strengths of the person being tested and cannot be compared to any other individuals. Such tests can typically be identified in the marketplace by the test asking the person to ‘describe themselves’. This type of test would not normally be used in recruitment and selection.

Normative tests measure quantifiable characteristics on individual scales. These scales can vary independently. Also the scores can measure the characteristics of an individual against confirmed patters of normality (e.g. normal distribution or Gaussian distribution). Normative testing allows people to be compared to particular groups, populations, or jobs.

Normative testing generally has a higher validity than ipsative.
