Jasperactive Digital Literacy (IC3) product - Yes, fully Web-based and platform agnostic.

Jasperactive Microsoft Office Specialist product - pending late 2020 release. Announcement

Running the current version of Jasperactive MOS on anything other than a Windows PC/laptop is not advised given that the courseware runs “live-in-the-application” (LITA) – i.e. local installation is required, and Chromebooks (non-business industry devices) have no hard drive.

If purchasing industry rated devices for your business CTE certification program is an option, Microsoft has some great education device offerings for under $250 each; your IT would have to update the OS and install Office 2019 Pro Plus, then Jasperactive MOS would work.

Note: U.S. and International Jasperactive clients only (non-Canada clients) - your license includes Jasperactive MOS with GMetrix. GMetrix has indicated plans to release, by September 1st, a Chromebook compatible platform for MOS learning. Please talk with your Certiport rep about this further. As for Jasperactive, we too plan to address this device need, with a projected timeline of between Nov-Dec this year. Lastly, Microsoft Web Apps are missing key exam objectives and domains in its current functionality. If these are addressed, this too will provide additional platform options.
