And why his school now relies on Common Planner to drive real progress.
Digital Harbor High School had a problem most leaders know too well: Teachers worked hard. But the work looked different everywhere. Lesson plans lived in different formats. Expectations were clear in theory — but hard to monitor in practice. Coaching cycles felt slower than they should be. And when you can't see what's happening across classrooms, you can't improve it. That's what brought Assistant Principal San Filippo to Common Planner.
"I needed one place where every teacher could work the same way."
Jeff knew his team needed two things:
Common Planner gave him both. Teachers plan in one shared structure. Objectives, standards and exit tickets stay front and center. Leaders and coaches can see — at a glance — where plans are strong and where teachers may need support. The best part? Teachers bought in quickly because the system felt designed for them, not imposed on them.
Before Common Planner, Digital Harbor High School's instructional team had to dig through plans, documents, and emails to prep for coaching.
Now?
Jeff says the consistency has made a clear difference in the clarity of instruction his team is seeing during observations.
Jeff shared one early sign of progress in their overall efforts toward strengthening planning and instruction:
F rates in Quarter 1 dropped meaningfully compared to the previous year.
It's early — and he's cautious — but the direction is encouraging.
For Jeff, it's not just about this year's gains.
It's about building a sustainable rhythm where planning, instruction, and coaching finally work together.
What Jeff appreciates most?
"Common Planner brought us the clarity we needed," he said. "It helped us move from everyone working hard… to everyone working together."
Digital Harbor's story shows what's possible when every classroom runs on the same playbook — and every teacher gets the support they deserve.
If you're trying to build stronger planning habits, tighter alignment, and better instruction across your school…
Common Planner gives you the system to make that happen.
