Forensic practice is more and more under scrutiny, both from the general public and the scientific community. Press reports about forensic examination in criminal cases regularly question the scientific foundation of forensic science and challenge the results of its analysis and interpretation (Hsu, 2015). In 2016, a report from the President’s Council of Advisors on Science and Technology (PCAST) entitled “Forensic Science in Criminal Courts: Ensuring Scientific Validity of Feature-Comparison Methods” (President’s Council of Advisors on Science and Technology, 2016) was released. This report emphasizes the importance of the validity of methods for the credibility of forensic science. In their 2017 annual report, the UK forensic science regulator also stressed the importance of the validity of the methods in the accreditation process:

The accreditation system is predicated on organisations being: a) accountable for the quality of their work and, b) able to demonstrate through regular audit and through evidence of staff competence and method validity that they are sustainably competent to produce reliable results.
