The Premier Chrome Extension Manager is a system that provides an organization with maximum flexibility to dynamically assign Premier Chrome Software licenses to users as needed. These licenses are so easily managed that your organization is allowed to assign them to an individual, NOT a specific piece of hardware or device. When it comes to having access to any of our applications, users can install the Premier Literacy Chrome Tools onto any device that supports Chrome and Chrome extensions.
Volume Licenses are purchased directly from Premier Literacy. For secure access, Premier Literacy provides your organization with a user name and password that is unique to your account. Once your Chrome Extension Manager account is setup, your organization can quickly assign (and re-assign) licenses to any person at any time. This makes it much easier to manage your total number of licenses across all individuals who may need access throughout the year.
The Premier Chrome Extension Manager always puts you in full control of your literacy tools. Premier Chrome licenses go wherever you go and you can use the extensions anywhere at anytime: school, home, work.
One License lets your students access all of Premier Literacy Extensions
