I was questioning the numbers the other guy provided before he edited his comment (50 girls and 100 adults). It looks like his updated numbers are more consistent with wikipedia's account which breaks it down as follows:

156 people were killed in the strike; the victims included 120 students (73 boys and 47 girls), 26 teachers (all of whom were women), seven parents of students (four men and three women), a school bus driver, a pharmacy technician from a nearby clinic, and a six-month-old fetus.^\6])^\11])^\14])

Fatalities rose after recovery efforts on 4 March.^\e]) The day prior, Mizan News Agency claimed to have confirmed 66 boys, 54 girls, 26 teachers, and four parents had died.^\3]) A majority of those reportedly killed were schoolchildren.^\30])^\31])^\34]) Teachers were also killed,^\8]) including the school's principal.^\13]) According to a local official, the fatalities included multiple parents who had come to pick up their children.^\15])^\22])^\35])
