Summary
Houston County School District shows how sustained commitment to assessment data can reshape instruction, district structures, and a culture of student growth.
When the leaders of Houston County School District in Georgia describe their assessment journey, they don’t start with a tool. They start with a problem.
Before MAP Growth, district leaders say they were “data rich and information poor.” State assessment data arrived too late in the year to act on—what senior director Steven Hornyak calls “autopsy data.” Without a universal screener, the district had no early signal about where students were in their learning, and no shared vocabulary for talking about it.
That changed in stages across more than a decade. MAP Growth started small—replacing a gifted screener in a few grades—and expanded when principals saw its potential. The superintendent’s backing made the work institutional. A district-wide professional learning structure called Leading Edge built shared capacity. Master schedules were rewritten to include Academic Opportunity Time targeted at the foundational skills the data revealed.
The most striking change came in 2023, when Houston County rewrote its mission statement. The original was “to produce high-achieving students.” But leaders kept asking why growth—the lens MAP had brought into their conversations—wasn’t reflected in the words the district used to describe its purpose. The new mission: “to produce high achievement for all through continuous growth.”
This is the part of the story that doesn’t fit on a marketing slide. A district changed its mission because the discipline of being honest about student data demanded more accurate language for what they were actually trying to do.
There’s an equity dimension worth surfacing too. Growth data recognizes lower-SES schools for what they’re accomplishing with their students, rather than being compared to schools with very different starting conditions. It also enables a harder conversation: students who arrive behind need accelerated growth, not average growth. Both sides of the coin matter.
When asked what advice they’d give districts earlier in the journey, the Houston County team didn’t talk about implementation playbooks. They talked about commitment.

When asked what advice they’d give districts earlier in the journey, the Houston County team didn’t talk about implementation playbooks. They talked about commitment. As assistant superintendent Lazunia Frierson put it: “Don’t just invest financially. Invest emotionally. Invest purposefully.”
For policymakers and district leaders thinking about assessment, Houston County is a useful reminder that the question isn’t whether to use the data. It’s whether the structures around the data—the professional learning, the schedule changes, the leadership commitment, the willingness to update the mission—are in place to let it do real work.
At NWEA, we’ve spent forty years building measurement that educators trust. But Houston County reminds me that measurement alone doesn’t change a district. The organizational commitment around it does. Our next chapter is about meeting districts on both sides of that equation—measurement that’s worth trusting, and connections to instruction that don’t require a decade of structural reinvention to put in place.
Key takeaways
- Assessment data has greater value when educators receive information early enough to identify student needs and adjust instruction.
- Creating a data-informed culture requires more than adopting an assessment; it takes sustained leadership, professional learning, and structures that turn insights into action.
- Houston County made continuous growth a districtwide priority, shaping professional learning, dedicated intervention time, and a rewritten mission focused on growth for all students.
