The 3rd GEDNAP Workshop will take place on 19 February 2026.
Attendees will meet in-person in the Hotel Moevenpick, Muenster (Germany) and remote attendees will dial in virtually. In addition to the presentation of the evaluation of the GEDNAP proficiency tests 70 & 71 there will be scientific presentations focussing on research & development in the field of forensic DNA analysis.
The online registration as a participant or as a speaker at the 3rd GEDNAP workshop is still possible.

The 2nd GEDNAP Workshop took place on 21 February 2025.
Attendees met in-person in the Hotel Moevenpick, Muenster (Germany) and remote attendees dialled in virtually. In addition to the presentation of the evaluation of the GEDNAP proficiency tests 68 & 69 there were presentations focussing on forensic DNA extraction and on the boosting field of forensic investigative genetic genealogy (FIGG).

The sending of certificates of attendance has been finished on 14 March 2025.

The GEDNAP Proficiency Tests 68 & 69 have started on 15 July 2024.
The deadline for result submission was 06 December 2024.
The evaluation of the results will be provided to the participants on 21 February 2025 during the 2nd GEDNAP Workshop (Muenster, Hotel Moevenpick).

The paper challenge files of the GEDNAP Proficiency Tests 68 & 69 (module 7, biostatistical calculations) haven been sent out today to the participants by email.
Both calculation methods that are recommended by P. Schneider et al. (2009) Int J Legal Med 123:1–5), i.e., LR and RMNE, are expected. Only the allele frequencies that were observed in the course of an ENFSI population study (source: “Europe” in STRidER_frequencies_2019-08-02, https://STRider.online) sh all be used. They can be downloaded from the GEDNAP website (https://www.gednap.org/wp-content/uploads/2020/09/STRidER_R2.zip). For rare alleles the recommendations (W. Ulbrich et al. (2016) Rechtsmedizin 26: 291-298) shall be followed. The frequency of rare alleles (fmin) shall be estimated according to the NRC report (1996). If the estimated fmin is below 0.001, one shall use the value 0.001. The calculation steps must be documented by a print-out. The employed software version must be named. Please note that the calculations have to be executed without the correction factor ‘theta’ (i.e. with a theta value of zero).
The deadline for result submission will be 06 December 2024.
The evaluation of the results will be provided to the participants in February 2025.

The GEDNAP Proficiency Tests 66 & 67 started in June 2023. The deadline for result submission was 04 December 2023.
The evaluation of the results was provided to the participants in February 2024 by means of the GEDNAP workshop.

A new release of STRidER (STRs for Identity ENFSI Reference Database), the expanded and enhanced version of the ENFSI STRbASE (2004-2016), is available here since March 30, 2020: https://STRidER.online).
In Germany it is recommended to use most recent the European allele frequencies as a standard. To receive periodic news and stay updated about STRidER, you may register here for the STRidER newsletter:

For the biostatistics modules of the GEDNAP proficiency tests in 2020 the recent allele frequencies [source: "Europe" in STRidER_frequencies_2019-08-02] will be used as well.

The deadline for result submission of the participants of the GEDNAP Proficiency Tests 70 & 71 ended on 05 December 2025.
The evaluation of the results will be provided to the participants during the 3rd GEDNAP Workshop on 19 February 2026 in Muenster, Hotel Moevenpick.

What’s New for GEDNAP 70 & 71?
We’ve made some significant enhancements to this year’s tests:
• Expanded STR Modules: Modules 1, 2, 5, and 6 now include an interpretation component, specifically addressing “Who has contributed to stain 1, 2, 3, and 4?”
• New Biogeographic Analysis Module: We’ve added Module 14, focusing on the biogeographic analysis of three reference samples.
• Quantitative Parentage Testing Evaluation: Module 13 (Parentage Testing) will now be evaluated quantitatively, providing a clear pass/fail result based on both STR typing and biostatistical analysis.
These updates aim to further enhance the comprehensiveness and utility of the GEDNAP proficiency tests.

Due to numerous late registrations and the new parentage testing module the result submission mode has not been activated so far. In the next week (i.e., week 45), entering results will be made possible. Participants will be informed immediately after activation.
