Read only template that prevents altering any data?

Greetings!  We are using Primavera 14.2.0.0 in an academic environment.  We need our students to access all of the default projects that come embedded with the software however it's critical that the original data remain undisturbed.  We have tried the "read_only" template however it permits considerable editing and alteration.  In the user account set-up, we have also unchecked every check box and modification option without success.

Does anyone have a suggestion as to how we can display all of the project data without disturbing the content?.
