I am applying for a librarian job where I work (a public school). Although the job listing does not list IT experience as one of the required knowledge, I know that the current librarian spends a large part of her time repairing the hundreds of computers in the building. This includes troubleshooting hardware and software problems, upgrading Windows, etc. I have a reputation in my workplace for being able to fix computer problems, but I'm going up against other applicants who can say the same. Is there some kind of qualification I can earn that will demonstrate to employers that I can keep their software/hardware running, which will be understandable to a hiring team that isn't in IT?
