Aims

01
The exchange of experience, quality control and stimulation of cooperation between the members
02
Making available scientific knowledge and findings in the field of interest
03
Organisation of scientific meetings ­– but such meetings will be held only after consultation with the ISFG

Membership

Membership of the English Speaking Working Group (ESWG) is open to all English speaking members of the ISFG and may be obtained by application to the secretary of the group. There will be no membership fee in addition to that payable to the ISFG.

To apply for membership, please complete this form and send it to the Secretary, Denise Syndercombe Court (denise.syndercombe-court@kcl.ac.uk), using the subject line as described in the form.

Proficiency Test

For many years, the ESWG has organized an annual proficiency testing programme with a special focus on relationship testing, including both wet testing and paper challenges. The programme is held once a year; in the most recent round, around 60 laboratories participated. It currently consists of three parts:

A
Wet Exercise
This exercise typically involves a paternity or maternity case. Each participating laboratory performs STR (or SNP) analysis to solve the case. All submitted genotypes are compared across participants, along with the calculated likelihood ratios (LRs) and conclusions.
B
Paper Challenge
This exercise presents a series of challenging kinship case questions, which may include expanded pedigree testing, mutation events, and lineage testing. Using the case descriptions and genotype data provided, each participant performs biostatistical calculations and reports LRs together with case conclusions.
C
SNP Exercise
Introduced in 2024, where each participants are ask to generate SNP genotypes from the provided samples. Any SNP typing method may be used. All submitted SNP genotypes are compared between participants. This exercise does not include kinship questions.

The registration deadline is normally in April. For further information or to sign up, please contact the head organizer Daniel Kling (daniel.kling@rmv.se).

Next meeting

The 2027 ESWG Scientific Meeting will be held in Sweden in May 2027.

Summary of the ESWG Members' Meeting 2026

In connection with the ISFG Congress in Montréal, Canada, in August 2026, the ESWG Member meeting was held. Approximately 50 members attended.

In brief, the Board was re-elected for another two-year term. ESWG's financial position is healthy and a discussion was held on how part of the funds could be used. The Board was tasked with taking the proposals from the discussion forward. A new membership application procedure was presented and approved. To apply for ESWG membership, applicants must complete an application form and submit it to the Secretary. This also applies to current members, who must reapply for membership (see details at our webpage). Daniel Kling presented a summary of the progress of the ESWG proficiency testing workshop. Lastly, a proposal was put forward by the Department of Forensic Genetics, National Board of Forensic Medicine, Sweden, to host the 2027 ESWG Scientific Meeting. The proposal was approved, and the meeting will be held in Linköping, Sweden, in May 2027.

Summary of the 2025 Scientific meeting

19th - 20th May

ESWG_2025_Meeting

The 2025 scientific meeting of the English Speaking Working Group, organized by the Department of Forensic Sciences, Norway, took place in Oslo, Norway, from May 19 to 20. It was an engaging meeting with around 70 participants and 25 scientific presentations covering topics such as forensic investigative genetic genealogy (FIGG), kinship analysis using SNP panels, epigenetic age prediction models, ancient DNA studies, and ethical considerations in donor conception. Adam Staadig from Sweden received the award for best presentation, which focused on experiences from the implementation of a SNP panel in casework. We thank Marguerethe Stenersen and colleagues for organizing this successful meeting!

Summary of the 2023 Scientific meeting

15th - 16th May

ESWG_2023_Meeting

The meeting was hosted by Denise Syndercombe-Court and colleagues at King’s Forensics at King's College of London. There were around 70 participants and 18 presentations covering various topics related to DNA analysis, genetics and kinship (such as biostatistics, SNP marker panels for kinship testing, investigative genetic genealogy, case reports, etc).
