This is correct.

Admin may see some raise but it is far more common that teachers get a bigger percentage. If nothing for just PR reasons - if you give everyone a 5% raise the people at the top get a bigger dollar figure than the average teacher in the eyes of the media.

Anything other than standard Ch 21 contract probably gets a little boost, but not the same rate as everyone else. Your contract is more individualized (even though it may be on a ladder on the back end that you can't see)
