CLS Recertification

You paid a lot of effort and money into becoming a "Certified Lubrication Specialist"?

Then you are one of about 1500 lubrication experts worldwide who do not only take care of lubricants, but also the application and therefore the client itself.

Your expert knowledge shall stay up-to-date on a long term basis – therefore the vailidity of your CLS certificate is restricted for only 3 years.

STLE certifications are valid for three years after you pass the Certified Lubricant Specialist™  exam. Prior to the end of this period, you must complete the requirements below to renew your certification.  If you do not renew your certification within the given time frame, you will have to retake exam.

In addition a renewal fee has to be paid to the STLE.

Alternatively, you can, of course, also retake the CLS exam.

If you want to renew your certification, please apply for it directly at the STLE Website

If you keep especially an eye on the easy to handle requirements 1, 2, 6, 7 and 8 from the beginning, you will have an uncomplicated recertification procedure!
