Looks like the school have dug themselves into a hole here along with a lack of communication between staff.
Male head? Or a female head who had a child and then went back to work that afternoon?
The trouble with school statistics is that many will quote them calculate then but few understand them.
The statistics year works from September. 5 days off in September is approx 75% attendance. This rings alarm bells. 5 days off over the year is approx 97.5% attendance.
Schools don’t, but should, have to follow all aspects of workers rights The logic being they are pupils not workers! You can get caught in grey areas of misunderstanding.
You may need to ask for a meeting with the head be calm but forceful. Ask for explanations of why going on report etc.
State examples when you thought it was all sorted out but events showed it wasn’t.
“What would you do if it was your daughter” etc. “What would you do if it was you?”
With your daughter going on report others will ask why etc. It’ll come out in a way she probably doesn’t want it to. Go down mental health route/school refuser.
Take a note book into meetings and write things down. Ask for clarifications, make the meeting go at your speed.
Dress smart.
Be in charge.
No joy there? Then go to governors.
