Elba Public School teacher Mike Miller, center, teaches a computing class to middle school students, including eighth-grader Devanee Spilinek, second from right, on May 1, 2014. Elba Public School has an average daily enrollment of 25 or fewer students in ninth through 12th grades. Next year, it is on track to stay that way. Because of a state law, however, that means the school might be forced to close its doors. Superintendent Mikal Shalikow and the school board are searching for options, from bringing in students to unifying or even consolidating with another school. But while Elba's issue is a question of how to keep its school open, as in many small towns, it is also a question of whether the community will survive. (AP Photo/The Independent, Barrett Stinson)
