These data were collected to support the development of statistical approaches to the evaluation of handwriting as forensic evidence. Each enrolled participant provided handwriting samples at three data collection sessions, each at least three weeks apart. At each session participants completed a short survey and transcribed the contents of three prompts, each three times. This repository includes 27 scanned writing samples from each of 90 participants, making 2430 handwriting samples in total. In addition, survey data are available in table format including a few demographic variables and session specific information for each participant. Data were collected by researchers at the Center for Statistics and Applications in Forensic Evidence.


This work was partially funded by the Center for Statistics and Applications in Forensic Evidence (CSAFE) through Cooperative Agreement #70NANB15H176 between NIST and Iowa State University, which includes activities carried out at Carnegie Mellon University, University of California Irvine, and University of Virginia.
