Bulloch County's recent public high school graduates posted impressive gains on the ACT, one of the two major college-entrance exams, but there is a catch. Far fewer members of the Class of 2014 took the ACT compared with the classes of 2011-2013. That's largely because for two years, 2010-11 and 2011-12, the school district paid for students to take the ACT, said Hayley G. Greene, the system's public relations and marketing specialist.
