Successful completion of the German-language CLS certificate course in May 2026
Our German-language Certified Lubrication Specialist (CLS) preparation course took place from May 4 to 7, 2026, at the OilDoc Academy in Brannenburg.
Immediately following this, on May 8, 2026, all participants took the official CLS exam administered by the STLE (Society of Tribologists and Lubrication Engineers)—the first time the exam was conducted online with proctors present on-site at OilDoc.
We would like to extend our heartfelt congratulations to all graduates on passing their exams and earning the internationally recognized Certified Lubrication Specialist (CLS) certification!
We are particularly proud of the successful graduation of our esteemed colleague Michaela Stephan from the OELCHECK Sales Department. As the only woman among a group of industry professionals, she passed the challenging CLS exam thanks to her energy, perseverance, and dedicated study. We say: Hats off to you and congratulations, Michaela!
Premiere: CLS Exam with In-Person Proctoring at OilDoc
A particular highlight this year was the CLS exam on May 8, 2026, which was held for the first time as an online exam with proctors present directly in the training rooms of the OilDoc Academy.
After consulting with the STLE, we were able to offer this exclusive exam opportunity due to high demand. Unlike standard webcam proctoring, the exam was administered on-site under supervision—a convenient and stress-free alternative for the participants.
This combination of an intensive preparatory course followed by an on-site exam allowed the graduates to immediately apply their newly acquired knowledge under ideal conditions.
