For an alarming number of new teachers, the school gates have turned into a revolving door. Expert estimates anticipate that nearly half of this year's new hires will leave teaching within the next three years. In addition to the direct, negative impact that teacher flight has on student achievement, districts are waking up to the reality that turnover on this scale is costing them thousands, even tens of thousands, of dollars for every teacher that must be replaced. In an effort to assist districts in addressing the reasons for the rampant turnover and to understand its sources, Gabe Soumakian, an assistant superintendent for the human resources department at Burbank Unified School District, developed a FileMaker Pro database which can be used for data collection, aggregation, and analysis. Once the data is gathered, evaluated, and reported, the information can be used to reduce teacher turnover and the associated costs. While technology tools are not a panacea, they can be leveraged to support data-driven decisions related to staffing and to strengthen the safety net every new teacher needs to be successful. Fortunately, these tools are readily available to most districts and can be implemented in a timely way.
