Training and Development Policy Wiki

We are working on developing content for integration into an entry-on-duty system that will help new employees become oriented to the Bureau. Has anyone else developed content for this purpose? We are looking for ideas as to what types of content might be of greatest value. We already have plans for an acronym list/game, virtual tours of facilities, stories of other employees' first day on the job, video welcome from the Director, etc. but are open to other ideas. We also are thinking about a Facebook or social media site for new employees and are wondering whether anyone else has done this and whether it was successful.
