What kind of training is required to be a civilian employee / resident on a starship?

The Enterprise D in TNG has civilian employees on board, such as Mot the barber, Ms. Kyle the school teacher, and Guinan's wait staff in Ten Forward. There are also families on board.

What training are they required to complete in order to be permitted to live on a starship (apart from training required for their own careers)?

Are they required to have training in basic ship functions and emergency procedures (in case of a ship disaster), or in basic combat training (in case the ship is boarded by hostiles)? If so, is this training normally completed prior to becoming a resident on the ship, or is it typically completed on board?
