Yes, and the part that makes it worth listing is that somebody can check it.
Every certificate has a public verification page. An employer opens the link and sees the name on the certificate, what it was earned for and the count behind it, without an account and without taking your word for it. Getting the link is free on every plan: open Achievements in the profile menu, select the share icon on an earned certificate, and choose Copy link or Open credential.
Get the name right first
The verification page shows the name on the certificate, so it has to be your real name rather than a username. You can set it once, and after that it is fixed, which is what makes the page worth trusting. See Your profile and certificate name before you share anything.
Where it goes on a CV
A certificate belongs under the heading your other credentials are under, and the verification link belongs next to it so nobody has to ask. On LinkedIn the share menu has Add to LinkedIn, which fills in the certification entry for you. That option is Pro; Copy link is free, and pasting the link into LinkedIn by hand gets you the same entry.
How to describe it
Describe it as what it is. It is a simulator: you worked a help desk queue, with the tickets, the tools, the callers and the write-ups, and the certificate records how many you resolved correctly. That is practice and it is verifiable practice, which is a real thing to say in an interview and a much better thing than implying it was a job.
What it answers is the question every entry-level IT candidate gets asked and cannot answer: what have you actually fixed. Having a Workstation OS imaging run, a mapped drive that would not reconnect and a printer nobody could find in the list to talk about is the point of it.
If the role asks for hands-on experience you do not have yet, saying “I have worked several hundred simulated tickets across accounts, hardware and mail, and here is the record” is both honest and more than most applicants bring.
Specializations
Certificates are the ladder. Specialization badges sit beside them in Achievements and say where the work was: fifty resolved tickets in one category earns that category’s badge, for example Network Specialist or Access Specialist, and fifty in every category earns Full Spectrum. That is the sharper line when a role has a focus.
The public page verifies the certificate and the ticket count behind it. The badges are in Achievements for you to quote. See Points, tiers and badges.
