More than half of CPS teachers leave their schoolswithin five years; African American schools hit hardest

About 100 Chicago schools suffer from chronically high rates of teacher turnover, losing a quarter or moreof their teaching staff every year, and many of these schools serve predominantly low-income AfricanAmerican children, according to a study released Monday by the Consortium on Chicago School Researchat the University of Chicago.

In the typical Chicago elementary school, 51 percent of the teachers working in 2002 had left four yearslater, by 2006, while the typical high school had seen 54 percent leave. These findings surface at a timewhen many principals are scrambling to find qualified teachers for hard-to-staff schools.

This study, The Schools Teachers Leave: Teacher Mobility in Chicago Public Schools, reflects theConsortium's commitment to study education issues that are top priorities in Chicago and districtsnationwide. It was funded by the Joyce Foundation, which works to close the achievement gap byimproving the quality of teachers in schools that serve low-income and minority children.

While some teacher mobility is normal and expected, high turnover rates can produce a range oforganizational problems at schools, such as discontinuity in professional development, shortages in keysubjects, and loss of teacher leadership. Previous research also indicates that schools with high turnover aremore likely to have inexperienced, ineffective teachers.

"This is particularly troubling because the vast majority of schools with chronically low stability strugglewith very low levels of student achievement," wrote Elaine Allensworth, an interim executive director at theConsortium and the study's lead author. "These schools desperately need to show improvements in teachingand student learning, but year after year they struggle to hold on to teachers."

This report examined the factors associated with high mobility rates, including teachers' backgroundcharacteristics, school structure, students' characteristics, and workplace conditions. The data includespersonnel records from about 35,000 teachers in 538 elementary schools and 118 high schools from 2002-03to 2006-07. It also reflects teacher and student survey responses, student achievement data, schooldemographics, crime statistics and block-level census data. The Consortium does not have access topersonnel records of teachers in charter schools, so these schools and teachers are not included in the study.

The key findings include:

  • Teacher mobility rates at schools with low teacher commitment are abysmal-67 percent inelementary schools leave within five years, and 76 percent turn over in the high schools. These areschools where teachers do not feel loyal to their schools, would not recommend their school toparents, and do not look forward to teaching every day.
  • In the schools with the best workplace conditions, teacher turnover averages about 10 percent eachyear.
  • Many of the teachers who leave their school each year go to other CPS schools; however, thepercentage of teachers remaining in CPS has declined in recent years.
  • Teachers of all races are most likely to leave predominantly African American schools than mixed-minority, predominantly Latino or integrated schools -- although white and Latino teachers leavethese schools at slightly higher rates. Systemwide, the mobility rates of white teachers have beenincreasing in recent years.
  • In elementary schools, teachers' perceptions of parents as partners in students' education arestrongly tied to stability; in high schools, teachers tend to leave schools with the highest rates ofstudent misbehavior.
  • First-year teachers are far more likely to leave their CPS schools after one year, especially inelementary schools, than their more experienced colleagues -- 33 percent of new teachers leave inone year, compared to 18 percent among those teaching two years or more. These one-year retentionrates did not improve during the five years analyzed.
  • Small schools have higher mobility than large schools, even when controlling for enrollmentdeclines.
  • Teachers are more likely to stay in schools where they shared with their colleagues a strong sense ofcollective responsibility and innovation, and in schools where they trust their principals and viewthem as strong instructional leaders.

While the average CPS school does not lose many more teachers each year than the typical school inIllinois or across the nation, these losses add up over time and create obstacles for sustaining newinitiatives and staff training, the study reveals. Moreover, the vast differences in teacher mobility acrossschools perpetuate inequities in hard-to-staff schools. High turnover forces principals to constantlydevote vast amounts of time and energy for recruiting, hiring and mentoring staff - and this divertsattention from other vital school improvements.

"Many schools are likely stuck in a cycle of teacher loss that is hard to break - teachers leave because ofpoor school climate and low achievement, but these are hard to improve when there is a constantturnover of teachers each year," the authors wrote.
