Quality Control

We take pride in the quality of our work and operate a universal quality control and peer-review process.  The work of every expert is checked by a second member of scientific staff.  In many larger cases, a number of our experts will be involved in various aspects of the analysis and checking procedures.  No work leaves the laboratory without these checks and reviews.

Quality control/checking is a key part of the Forensic Science Regulator’s Codes of Practice and Conduct for all forensic practitioners.

Regulation and international standards

J P French Associates is committed to meeting the highest possible quality standards.  Following the introduction of the Forensic Science Regulator, we are developing our practices in line with the FSR’s guidance and internationally recognised ISO standards for forensic laboratories and practitioners across the UK.  We are working with the Chartered Society of Forensic Sciences to achieve accreditation to the FSR’s Codes and ISO 17025; using a quality management system which has been developed by the CSFS, we are working to meet the requirements for accreditation and provide the best quality evidence.

JPFA staff played an integral part in the design of the Regulator’s Appendix to the Codes for Speech and Audio Analysis, and also the international code of practice for forensic phonetic and acoustic practitioners, implemented by the International Association for Forensic Phonetics and Acoustics (IAFPA)IAFPA code of practice.


Part of our commitment is to ensure a secure service. We have experience of handling sensitive materials, both in physical and digital formats, and work within an established security framework. Further to this, our laboratory has been assessed and certified for security, and all of our scientific and administrative staff have security clearance status. The laboratory has a secure CJSM email account through which we can receive instructions, documents and recordings. For more information, please contact enquiries@jpfrench.com.
