Can many iPads have a "master" Apple ID and a second, "personal" Apple ID?
The Apple Configurator app was designed for deploying large numbers of iOS devices within institutions like schools. The Apple Configurator documentation explains the three different supported configuration modes (Prepare, Supervise, or Assign), and a video introduction is also available. Based on the wording of your question, the either the Prepare or Supervise method will likely be the best choice.
