Bad experience with inconsiderate staff with attitude; supervisor even less helpful and with worse attitude Staff with attitude started bad experience ; provided my drivers license for ID ; Staff didn't except written certification of completion of training as prerequisite for testing ; Oakstone representative provided certificate of training but unacceptable by staff ! Finally allowed to take exam Passed exam but staff member lost my drivers license , needless to say they say exam maybe invalid due to lack of ID

The booking system is almost impossible… The booking system is almost impossible to wade through. It's like it was designed by someone that had never used a booking platform. Why companies use Prometric I'll never know. I tried to book an exam for one of my staff and ended up, after 30 minutes of circles, giving up. I'll be complaining to The CIOT about this too.

Horrible Service Can't believe CSI uses this terrible service. I logged in for my exam. Got my security check done. I waited for my proctor for over 15 minutes and no one showed, so I disconnected and tried to reconnect. Now it says my confirmation # doesn't work. Tried all the troubleshooting on Prometric website and after several attempts, finally got a person on chat who couldn't help me. They referred me back to CSI who says I have to reschedule my exam. And they wouldn't even do it right away. If you have other options, don't go through CSI.

Stay far away from this company...SCAM ALERT! I made my appointment in February 2024, paid my money to go to a site that is now closed. They just sent me a notice saturday evening before a monday morning onsite exam. They make no mention of a refund or where I can get it done. This was the last day for me before I have to send my results in for my university. This company is a scam. Notify your bank for a reversal of charges. Report to the BBB ASAP!

Absolute garbage Absolute garbage, just reading their brochure notifies you how invasive and unwaveringly authoritarian this setup is, leaving you with no power, and some random unknown individual (or even an AI with their updated services) having ultimate control over whether or not you are following their rules.
