In the US, the common handwriting style taught in the late eighteenth and early nineteenth centuries was the English Old Round Hand style. The letters are often up on the board and we have models of lower case and upper case printed and script letters. We are shown as children drawings of letters and asked to simulate them by drawing matching letters.

The action of writing requires a complex series of skills we begin learning in grade school. Then imagine being able to rule every one of them, except one, out from having written an excerpt of writing. Imagine the number of people in the world. It is a subjective test, totally affected by the examiner’s experience level. That said, some experts may require more evidence or different material to reach a similar conclusion. It is the subjective observations of a document examiner that determine whether two writings were made by one individual. If you wrote it on a piece of paper 10 times, none would exactly overlay another. It varies even within the same writer or written document. With fingerprints or DNA, you have an absolute identification. Handwriting is a form of forensic science that is somewhat unique. It is for these reasons that the handwriting of a mature individual is identifiable. It is difficult to change movements quickly in order to create different style letters. Writing skills take a long time to develop in a person and as such they tend to exert a strong influence on the writing of an individual. Writing skills learned over a short period of time will continue to develop and evolve as the writer develops further skills. The person is essentially applying the motor and coordination skills they know from their own language and using them artistically to draw the second. If we think of a person immersing themselves into a second language, they begin writing in that language after only a few lessons. It takes time to develop the coordination of arm, hand and finger movements necessary to write script. It takes the average person many years to become able to write so that others can decipher the words.
