Late Policy

what would be a effective late policy for this school?
Students should be in school by 8, not 7:55
as for the classes, people should be in class when the bell rang, but the break should be longer, from5 minutes to 8 minutes. Therefore the students in the school will have time to gather their things and move to the next class while being able to use the restroom.
The kick out policy and lock out policy is plain stupidity and useless. To be honest, i went to the bottom of the reason why the tardy policy have gotten so suddenly messed up. It is simply because of two person, and i doubt those two person even know that it was their fault. This late policy on the classes could be negotiate with the teachers, however, this lock out policy have proven just extreme and unnecessary.
late policy in the school is a waste of time and learning. We pay lots of money to this school to receive education, if the students are simply locked out of the school, then where are our money? The head of the school needs to get some sense in her head and remove or readjust the school's policies.
