Three Questions for Your Last Board Meeting of the School Year
The cracks show in May. Although there’s often plenty to celebrate at the end of the school year, it’s also when the cracks appear in charter school boardrooms. Enrollment numbers that aren’t hitting the target. A leader who’s spent. A budget that worked on paper and didn’t work in practice. A facility decision that’s been sitting on the agenda since November and never quite got resolved. None of that is a failure. It’s data. And the boards that come out of May with real mom

The 4–6 Week Window That Decides Teacher Retention
Teachers are deciding right now. End of the school year is when teachers decide whether they’re coming back. Most of the decision is already made by the time you’re handing out summer schedules. The conversations you have in the next four to six weeks just confirm what they’ve been quietly thinking since February. Charter schools across Georgia are watching the same trend right now: teachers are taking shorter tenures than they used to, and they’re more willing to break contr

Why Most Strategic Plans Are Useless — and How to Build One That Isn’t
Summer can be the only stretch where a board can think. Summer can be the only stretch of the calendar where a charter school board can actually think. No emergency board meetings. No mid-year budget revisions. No personnel files landing on the agenda the night before. Just a few quiet weeks where the right group of people can sit down and ask: what is this school actually for, and are we doing the work to get there? It’s also when most strategic planning happens — and many s

When Accountability Stops Being a Spreadsheet: Reading Year 2 and Year 3 Results
The framework becomes a story. Year 2 results are landing for some Georgia charter schools right now. Year 3 results are coming. For schools approaching their first renewal cycle, this is the moment when a performance framework stops being a spreadsheet and starts being a story — about whether your school is on track, on the bubble, or staring at a hard conversation. That story starts getting written long before renewal materials are due. The schools that come through clean a

Georgia Charter School Budget Crisis: Managing Rising Costs in 2026
Georgia charter schools are facing a perfect storm of financial challenges in 2026. Teacher salaries continue climbing, healthcare and retirement costs are skyrocketing, facility expenses are rising, and enrollment patterns remain unpredictable post-COVID—all while per-pupil funding increases lag behind. We’ve worked in Georgia charter finance long enough to recognize the pattern: budgets don’t usually fall apart because leaders are careless. They fall apart because schools m

5 Budget Mistakes That Get Georgia Charter Petitions Denied
Here's something we don't love admitting: we've seen too many promising charter school petitions get denied over budget issues that were completely avoidable. Not because the petitioners weren't passionate. Not because their educational model wasn't strong. Because the budget section of their petition told a story the authorizer couldn't believe. We spent a combined 15+ years each on the authorizer side of the table — at both the Georgia Department of Education and the State
