You could but personally I would have an ID for the table that is Autonumber and an EmployeeID / TechID field that is indexed no duplicates.
The TechID is for your use. You may want that displayed in forms, reports,  badges, etc.
The Table ID is for Access to use.  You don't care what that number is.  It's only for relationships between tables.

I couldn't have said it better myself, Scott. :)

David Richard has a killer set up in the ABCD he is developing.  What you are trying to do he goes step by step on this.  Well worth the money.

good advice Scott, Also I have been going through Richards training and has been as you say worth the money. So next question If I have multiple types of training should that be broken into separate tables? the fields in the tables tend to grow so maybe just one table with all the records with the training type as a selection from a second table.

One table if it's the same "type" of a thing. Just make a field to differentiate them.

Got it! thanks
