You, as an academy Admin, can set terms and conditions for your academy's use. Users that match the criteria you set, would have to "agree" in order to be able to continue with the academy's usage.
To define your terms and conditions navigate to your admin panel, from Admin > My Academy, and select "Academy Terms".
You have the option to change the Title and add your own wording instead of "Terms and Conditions". Then continue and fill in the description of the terms. Once you are done with the description select the jobs and units or above units that these terms will apply or select that the terms will apply to all members of the academy.
Don't forget to enable the "Are these Terms & Conditions active?" before saving if you want your terms to be active!
