Student deaths as school bus passengers are generally quite low given the number being transported daily, but is certainly not zero And if you include incapacitating injuries (amputations, etc.) the stats are a bit higher There really is room for improvement:
NHTSANational Coalition for School Bus SafetyNHTSA, Circa 2012:
After releasing updated traffic safety facts over the summer, NHTSA said the average number of student fatalities in school bus crashes is now on average six per year, and an average of 12 student pedestrian deaths occur outside the bus, figures that mirror those of previously published federal data.
NHTSA updated its report "School Transportation-Related Crashes" to cover incidents recorded from 2001 through 2010. Of the 363,839 crashes over that period, NHTSA added that just shy of 3.5 percent, or 1,236 crashes, were classified as related to school transportation. In these crashes, 123 students under the age of 19 were killed.
...
Overall, 1,368 people were killed in school-transportation crashes, 72 percent of which were occupants of other non-school bus vehicles involved, for an average of 137 fatalities per year from 2001 through 2010.
More than 7 percent of the fatalities were school bus occupants. Of the total 102 school bus occupant fatalities, 62 student passengers.
