If you are putting training material together for NEW officials, wouldn't it be best to have them concentrate on the Federation rule book and not worry about the differences in the other codes? At least not yet.
No question focus on the NFHS rules (other than Texas and Mass.) is the primary focus, but especially on the level most new(er) officials work, confusion by coaches and spectators about what they see at upper level games fuels much of the confrontations that create problems.
There are literally hundreds of differences, but a relatively small number of major differences that tend to cause the majority of problems on lower level playing fields.
Although the focus should be clearly on the details and specifics of the NFHS code, identification and explanation of those "major" differences can better equip the new(er) official to defuse some of the more common confusions that tend to arise more frequently at lower level contests.
