Replacing a single teacher can cost a district between $9,000 and $21,000, according to the Learning Policy Institute. Across a year, that adds up to real money and real disruption for students. So at Upbeat, we sat down with Dr. Carrie Tisch, Assistant Superintendent of HR at Cook County School District 130, to talk through how her district actually keeps teachers.
Our recent webinar, Building a District Where Teachers Stay, was a candid, peer-to-peer conversation about the teacher retention strategies that hold up over time. Here are three ideas worth taking with you. The full story, including what Dr. Tisch told her board and what she'd tell a leader just getting started, lives in the recording.
The biggest mindset shift was simple. Staff engagement is a measurable input to retention, not a soft culture project. Upbeat's research with Dr. Matthew Kraft at Brown University, drawn from hundreds of schools over three years, found a clear link: when engagement goes up, retention follows close behind.
That relationship is what lets an HR leader make a financial case to a superintendent or board. When you can connect engagement to dollars and to student outcomes, the conversation stops being about morale and starts being about strategy. Dr. Tisch shares the exact language that worked for her in the webinar.
You can't act on what you can't see. The research points to a few drivers that matter most for keeping teachers: belonging and wellbeing, a sense of being effective at the work, and a clear connection to purpose. Each one points to a different kind of response. A building that's strong on belonging but shaky on confidence needs coaching and support. A building with the opposite pattern needs attention to culture and leadership.
When you measure precisely, the data tells you where to focus instead of leaving you to guess. That's how Cook 130's leaders decide where to put their energy each cycle.
The change rarely happens inside a survey. It happens in the conversation that comes after, when someone sits down with a principal, looks at the building's data together, and helps turn it into a concrete plan. At Cook 130, that someone is an Upbeat coach who works one-to-one with each building leader. As one Cook 130 school leader put it, "The discussions are driven by data and the results of the survey. It's not personal and you can speak openly."
In the webinar, Dr. Tisch and the Upbeat team walk through a real example from one of Cook's schools, where a single survey signal led to a few small changes and a noticeable turnaround by the next cycle. It's a clear picture of what the listen, act, and re-measure loop looks like in practice.
Dr. Tisch goes deeper on all of this in the Upbeat recording, including how she made the case to her board and what she'd tell an HR leader who's just starting out.
What are the most effective teacher retention strategies for school districts?
The strategies that hold up treat retention as a system: measuring staff engagement across the drivers that research links to retention, coaching leaders to act on building-level data, and re-measuring to see what worked. Cook County SD 130 uses this approach, and the full webinar shows it in action.
How does staff engagement affect teacher retention?
Engagement is a leading indicator of retention. Research across hundreds of schools shows that as engagement rises, retention tends to follow. Engagement data also surfaces teachers who stay but quietly disengage, which retention numbers alone can miss.
How much does it cost to replace a teacher?
The Learning Policy Institute estimates $9,000 to $21,000 to replace a single teacher, including recruiting, onboarding, lost productivity, and lost institutional knowledge.
