Everything is excellent but the issue is gate where there are watchmen and she has to take out hijab there
Which is haram.
Either speak to admin to allow her until she enter in school premises
If you explain inshallah they will understand I had many examples when patents explained the importance of the hijab it was permitted you must speak with them.
If still they will not allow them enrol her in the school where it is permitted .
Inshallah it will be resolved our prayers are with you.
