Handwriting analysis is an effective and reliable indicator of personality and behaviour, and so is a useful tool for many organizational processes, for example: recruitment, interviewing and selection, team-building, counselling, and career-planning.
The science of graphology uses at least 300 different handwriting features in its investigative approach. The graphologist's interpretation skill is in the psychological art of understanding the particular blend of - a typical analysis will involve far less).
No single handwriting feature proves anything specific or absolute by itself; a single feature alone can only identify a trend handwriting features - an expert is able to see the writer 'step off the page'.

Graphology theory and history:
A person's handwriting - the script - and its placing on the page express the unique impulses of the individual: logically, the brain sends signals along the muscles to the writing implement they control. By examining a handwriting sample, an expert graphologist is able to identify relevant features of the handwritten script, and the way the features interact. The features, and interaction between them, provide the information for the analysis. (No single handwriting sample will exhibit all 300 different features. It is the combination of features, and the interaction between them that enable a full and clear interpretation.
The aim in using graphology to analyse a person's handwriting must always be positive. The interpretation should enable people analysed to use the understanding gained, to help them live their lives to the highest level of satisfaction that they choose. In a professional or organizational context, graphology can play an important part in enabling working relationships to be forged that will enhance the quality of the group or team performance.
