Securing different pages by CAS Attributes

Currently the best way to do this is to hook into authorizer_custom_role to assign specific roles to your students and fac/staff, and then create custom post types with custom capabilities that allow viewing by certain roles.

Alternatively, you can use postmeta (or any custom fields plugin) to specify which roles have access to a page, and then enforce this in your page templates.
