Most discussions about school attendance focus on students. Now, U.S. Education Secretary Arne Duncan wants to talk about teachers.
Duncan has made teacher attendance one of the measures to determine which low-achieving schools receive federal improvement funds. So, for the first time, the federal government will collect data on how many days teachers miss classes each year.
The reason is simple: Research shows that students suffer a small, but significant decline in academic performance as a result of teacher absences.
In addition, the nation's public schools pay a big price -- as much as $4 billion a year according to the National Center for Education Statistics -- to hire substitutes to fill in for absent staff.
When he was CEO of Chicago public schools, Duncan was dismayed to discover that the system was spending more than $10 million a year on substitute teachers. He tangled with the teacher unions when he added teacher attendance data to school scorecards.
