The Home Language Code is located in the student profile, the family tab, and the LEP tab, but these do not update each other so you have to remember to add/edit all three sections. It would be a lot more helpful if they would update in all 3 locations when one of them is updated, because it is hard to remember that there are 3 different places to add/edit it and the code should usually be the same in all 3 locations as well.
