Questioned Documents

The CTS Questioned Documents Examination proficiency test is designed to reflect actual casework. The complex and challenging scenarios are constructed to accommodate a range of laboratory capabilities. Samples vary from ink markings to impressed writings to identification of a printing process. For those seeking a narrower focus, the Handwriting Examination proficiency test is designed solely for the examination and comparison of handwriting. High-quality digitally-produced photographs or digital images downloaded directly from our portal offer multiple exemplars and allow your personnel to really work this case.
