Police in American Samoa want school sports held earlier in the day to improve security.
This comes after three high school students were injured when their bus was attacked following a late night volleyball game two nights ago.
The students from Tafuna High School had just finished playing at Fagaitaua High School when people started throwing rocks at their bus.
The vehicle was extensively damaged and 3 students hurt.
Police have yet to make any arrests, saying it was too dark at the time of the incident.
Our correspondent in Pago Pago, Monica Miller, says education officials want parents to take more responsibility for their children's behaviour and to mete punishment for this incident.
"At the same time they are trying to get the police to step up enforcement but the acting commissioner of police, he is very adamant and he has said this in the past, it is best not to have these games too late in the evening because this could happen. It is really hard to control whereas if you have the school sports right after school then security is much better."
