Participants will examine digital images of bones to determine whether they are of human or non-human origin.

Sample Description: A digitally downloadable .tif file that contains four to six images, each including a scale (L-ruler). With tests consisting of digital test materials, participants are not limited to only on-screen comparisons and may use any other method; however, due to differences in printing technology, CTS cannot guarantee the quality of images printed from digital media.

Digital test materials are made available in January.

Additional Information: Digitally downloadable test materials, as well as response forms for all test formats, are only available on www.cts-portal.com. The information necessary to access the test materials will be provided via email to the primary contact on file on the day of the test release.

This test is included on CTS' Scope of Accreditation to ISO/IEC 17043.
