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:

  1. Clear expectations every teacher could follow
  2. A simple system to check whether those expectations were actually happening day-to-day

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.

Coaching is now faster, tighter, and more focused

Before Common Planner, Digital Harbor High School's instructional team had to dig through plans, documents, and emails to prep for coaching.

Now?

  • Coaches walk into meetings already knowing what a teacher is trying to accomplish
  • Feedback stays tied to actual plans and execution
  • Follow-up is tighter because everyone is looking at the same source of truth

Jeff says the consistency has made a clear difference in the clarity of instruction his team is seeing during observations.

And early student outcomes show promising movement

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.

"Common Planner helped us move from effort… to alignment."

What Jeff appreciates most?

  • Teachers finally share a common approach to planning
  • Leaders can support instruction without guessing
  • The entire school feels more aligned, more focused, and more accountable

"Common Planner brought us the clarity we needed," he said. "It helped us move from everyone working hard… to everyone working together."

For school leaders asking, "How do I bring real consistency to instruction?"

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.
