Okay, This was for a high school class (see techfutures.org and opensourcessis.org)

Student configured their portals as seen on www.eduperform.com

Each team created a parent portal for the district with schools as child portals.  You'll see this reflected in the urls.

tfxtreme.eduperform.com

teamorion.eduperform.com

And

teamorion.eduperform.com/SchoolExample1

tfxtreme.eduperform.com/SchoolExample

Reporting is aggregated at appropiate entity level (distrcit , school, etc)

 If prompted, use l/p

Eduperform/Techfutures06.

 This prompt is for the Reporting Services Server. It will show a parameterized report of CST year over year scores (California Standardized Tests). We use the ReportXP module.

AD... We don't necesarrily require AD for Reporting Services...we just have it set up this way. It can be made for anonymous or authenticated access.

AD integratio is really helpful if you host the network for the school or district. If so, then your AD roles and groups can be leveraged.  In WCCUSD as in CA, this is often the standard setup. As an Academy like program for vocational focused students, we manage our own networks. 

We're planning on using the AD module and Authentication for our administrative Intranet and students when they login. Testing is happening this week...so I'll repost our findings.

The most important consideration for DNN school setup is module  and skin licensing. Depending on vendor, some modules and skins can be licensed for the server, the domain, a parent installation, and/or a child installation.  Your budget will help you make these decisions. The more portals to support, the more need for tools...So far, however, this scale issue is easily addressed, if planned for accordingly.
