Many school systems in this country no longer teach penmanship, especially cursive writing. I strongly disagree with their decision to discontinue teaching penmanship.
The entire financial and legal system in the United States is based upon signature identification. Your driver’s license, passport and almost all forms of identification require a signature. If you have signed, witnessed and dated a document it is legally binding.
As a forensic document examiner (also called a handwriting expert), I testify in court regularly regarding the genuineness of signatures. I am also called upon to identify the author of anonymous letters by comparing the writing with known handwriting samples.
