COORDINATING THE ACTIVITY OF THE 
ACCREDITATION AND TECHNICAL 
DEPARTMENT FOR A DECADE has been 
a complex responsibility. The achievements of 
this period were possible only due to dedicated 
teamwork. The collaboration and communication 
of the Department team from the ISTA 
Secretariat, including the audit administrators 
and the contracted system auditors (SA) and 
technical auditors (TA), are our keys to success. 
Furthermore, the support and guidance of the 
ISTA Executive Committee (ECOM) and its 
Accreditation Working Group (AWG) must be 
commended.
The growth in the number of auditors and their 
expertise is summarised in the following table.
As can be seen, the total number of auditors 
increased to 33 (almost double) over 9 years and 
several categories of experts were introduced 
from 2019. In the same period, the number of 
system and technical auditors for standard tests 
increased, despite the fact that some colleagues 
decided to stop performing ISTA audits. Training 
and examinations of candidates to become ISTA 
auditors are also in progress, with the support of 
senior auditors and accredited members.
In the same period of time the number of 
accredited members increased, and at the end 
of 2025 there was a total of 161 laboratories and 
sampling entities already accredited.

The total number of accredited members 
increased by 36 over 10 years and there are four 
more members in the accreditation process, 
having been audited in 2025. It is thus estimated 
that there will be 165 accredited members in total 
in the first trimester of 2026. During the same 
interval, nine laboratories discontinued their 
ISTA accreditation (approximately one member 
per year on average).
At the proposal of ISTA members, from 2023 the 
Department has organised ten webinars focused 
on the requirements of the ISTA Accreditation 
Standard and important changes impacting 
accreditation status. They were received with 
great interest and each session hosted more 
than 200 participants from accredited and 
non-accredited members, as well as non-ISTA 
members. The sessions were also watched 
afterwards on the ISTA YouTube channel, and 
it is known that they are being used as training 
materials in several laboratories.
The webinar topics were:
• How to address non-conformities 
identified at ISTA audits (www.youtube.com/

• ISTA samplers monitoring (www.youtube.com/

• ISTA analysts monitoring (www.youtube.com/

and Directive Acc-D-06B, two sessions (www.

• Management review (www.youtube.com/

With the aim to promote quality assurance 
principles and the ISTA accreditation 
programme, 15 workshops were successfully 
organised. Ten were designed for beginners 
and five for advanced laboratories. Four out of 
15 were provided online and the other 11 were 
held in different regions of the world. In 2025 the 
first workshop on Quality Assurance and ISTA 
Accreditation for beginners in French language, 
was also organised. This was done as part of
