no substitute

WASHINGTON – A year is a long time in a child’s education, the time it can take to learn cursive writing or beginning algebra. It’s also how much time kids can spend with substitute teachers from kindergarten through high school – time that’s all but lost for learning.

Despite pressure on schools to increase instructional time and meet performance goals, the vacuum created by teacher absenteeism has been all but ignored – even though new research suggests it can have an adverse effect in the classroom.

The problem isn’t just with teachers home for a day or two with the flu. Schools’ use of substitutes to plug full-time vacancies – the teachers that kids are supposed to have all year – is up dramatically.

Duke University economist Charles Clotfelter, among a handful of researchers who have closely studied the issue, says the image of spitballs flying past a daily substitute often reflects reality. “Many times substitutes don’t have the plan in front of them,” Clotfelter said. “They don’t have all the behavioral expectations that the regular teachers have established, so it’s basically a holding pattern.”

Clotfelter’s examination of North Carolina schools is part of emerging research suggesting that teacher absences lead to lower student test scores, even when substitutes fill in. And test scores have gained heightened importance, because the 2002 education law penalizes schools if too few students meet testing benchmarks. The goal is to get all kids reading and doing math at their grade levels by 2014.

Raegen Miller, a postdoctoral fellow at the University of Washington, is examining the impact of teacher absences on fourth-grade test scores in a large, urban school district that he chooses not to identify. His findings show that 10 teacher absences within a year cause a significant loss in math achievement. When the regular teacher is gone for two weeks, it can set students back at least that amount of time.

“Teachers often have to re-teach material, restore order and rebuild relationships after absences,” said Miller, who is conducting the research with Harvard University education professors.

Nationwide, the number of schools reporting that they used substitutes to fill regular teaching vacancies doubled between 1994 and 2004, according to Education Department data. The latest data showed more than a fifth of public schools use subs in this way.

Miller found big differences in teacher absence rates among schools in the same district. He said the “professional culture” of a school and the relationship between teachers and administrators affect absenteeism.
