Every person has distinctive characteristics and qualities, which influence their thinking, preferences and behaviour. The DISC Personality System is a tool that aims to help individuals increase in effectiveness as they identify and capitalise on strengths, whilst recognising potential limitations and blind spots.

DISC is a four-quadrant behavioural model based on the work of William Moulton Marston Ph.D. (1893 – 1947) to examine the behaviour of individuals in their environment or within a specific situation. The acronym DISC stands for the four personality styles represented by the letters: Dominant, Influencing, Steady, Compliant.
