Forensic examinations and comparisons of handwriting are performed by analyzing several features, including allograph construction, alignment, pen pause, fluency, arrangement, punctuation, and pen pressure. In the present study, documents with the same content and written by 60 healthy volunteers in their native language, second language and, a language they did not know (as indicators of their educational level) were examined. These documents were compared in terms of forensic document examination parameters using a magnifier with an LED desk lamp and an optical glass lens. Statistically significant differences were identified in allograph construction, fluency, and punctuation (p = 0.001, p = 0.000, and p = 0.002, respectively). Handwriting was found to reflect a person's command of language and to provide dues regarding their education level, because the use of writing increases with education, and the level of language affects allograph construction, fluency, and punctuation.
