Hello there! We had a similar issue with our office staff last winter. It is tough to plan training sessions when you do not know their baseline knowledge. I ended up using Examinizer
https://examinizer.net/ to map out everyone's technical abilities. It functions as a wonderful online platform for language and professional skills testing. They have a specific module that covers standard digital tools and basic workflows. The test takes about twenty-five minutes. The final scoring dashboard helped me see exactly who needed extra support. It saved us from wasting money on unnecessary training classes.
