Both K. and O. in the staff to children ratio requirements refer to the necessity of having additional staff who are readily accessible.  The jobs of these additional staff need to be clarified.  If these additional staff are administrative staff, that should be fine.  However, if these additional staff are staff members who already are directly responsible for children, that would be problematic.  They would have to leave their own classrooms with an inadequate staff to children ratio, in order to go to the other classroom and help.
