Can I disable certain classes from parent teacher conferences?

While specific classes cannot have this flag disabled for parent teacher conferences, you can go into a course record and set it so that the 'Include in Parent Teacher Conference' flag is set to "No" (this flag can be found on the General tab of any course record). If, for any reason, a parent is still seeing an offer to have a PTC with a specific teacher, it may be that the teacher teaches a course their child is taking that has the flag set to "Yes."
