Government funding for schools is partly based on student attendance. Public school systems have for decades drastically increased their number of employees at percentages far, far above the actual growth in student attendance.

And as Scott Shackford reports, this battle for student attendance has led to evolving tactics by schools. Some are notably authoritarian and controlling, but not all tactics are bad. Some methods of improving student attendance actually may help undo authoritarian public education policies. Here are four tactics public schools are using to keep attendance from falling.
