Parents
Parent notes
The note the school wrote, and the parent who read it.
A note is written once, on the student. The parent reads that note.
Absence, a fee reminder, or a circular can be the same kind of message with a different purpose.
The office sees who has not opened the note, if you choose to track that.
A reply comes back onto the student. The thread is not a lost chat.
Teachers can send a class note. The office can send a school note. Both land on the right names.
A wrong number is visible when a send fails. The student is not marked told.
The history stays on the student so a new clerk can see what was last said.
This desk uses the student list from the school record. It does not invent a second roll.
A new office staff member can send one class note on the first day.
The evening check is notes sent and notes that failed.
