An education expert says Indiana data on student discipline could make the state a target for federal review because of disproportionate numbers of males, minorities and students with disabilities being punished. The Equity Project at Indiana University says the Hoosier state is one of five states with male suspension rates higher than the nation for every racial and ethnic group. The group also saw African Americans account for nearly a third of students who lost classroom time to suspensions and expulsions. Data shows the number of Indiana school children facing suspension or expulsion from school has steadily declined in recent years. But students still lost nearly 600-thousand days out of the classroom in the 2012-2013 school year.
