The sun rises in the East. Grass is green. And teachers are the most important in-school factor in determining student achievement. This last truth has long guided the push for more robust teacher-preparation programs, heartier evaluation systems, and altered HR policies. This short report by Raegen Miller highlights another strategy, small but fruitful, for eking more out of today’s instructional workforce: Ensure that teachers come to school each day. Using data from the Civil Rights Data Collection survey, Miller discovers that, on average, 36 percent of teachers were absent (whether for sick or disability leave or vacation time) ten or more days during the 2009-10 school year. Nationally, these missed school days cost taxpayers $4 billion. Interestingly, about two-thirds of the variance in chronic-absenteeism rates exists between districts within states—highlighting the power that district policies and bargaining agreements play in determining these rates. (In that vein: Charter-school teachers were 15 percentage points less likely to be truant than their peers in district schools.) Miller further dissects the data by school level and student race (predominantly black schools face higher rates of teacher absenteeism), but he stops short of analyzing them by socioeconomic status—a key shortcoming of the report. (The coarse data necessarily used here leave further questions unanswered regarding total amount of leave taken and type of leave requested.) While not a comprehensive assessment, Miller’s report does bring this key inadequacy in K-12 education to the fore—and reveals some startlingly stark information.
