At Mastery Charter Schools, instructional leadership is rooted in clarity, equity, and impact. With over two dozen campuses, the network emphasizes frequent, high-quality feedback aligned to a rigorous internal framework.
At campuses like Lenfest, Clymer Elementary, and Pickett, leaders like Chris Ziemba, Heather Scheg, and Margaux Munnelly manage the challenge of providing consistent, rubric-aligned feedback to dozens of teachers—all while tracking performance categories that drive teacher advancement.
They needed a tool that could reduce the administrative burden of evaluations, provide a shared language across APs, and make it easier to support every teacher equitably.
Each leader carried a large caseload of observations, often relying on manually written narratives and personalized rubrics to meet Mastery's high expectations.
While leaders valued detail, they faced major hurdles:
Evaluation write-ups could take over an hour per teacher
Language and tone varied across APs, leading to feedback inconsistency
Promotion eligibility had to be tracked manually by averaging rubric-aligned scores
There was no easy way to surface trend data or link evaluations to coaching plans
"I want our coaches in classrooms—not behind desks rewriting the same language," said Chris Ziemba.
"Teachers need clarity on where they stand and how to grow. That's hard to do with disconnected systems," noted Heather Scheg.
Swiftscore provided more than a workflow fix—it gave Mastery leaders a system that supported clarity, consistency, and equity.
Through custom configuration, the platform now mirrors Mastery's entire instructional framework, including:
A 1–5 scoring scale aligned to performance bands (e.g., Associate, Advanced, Master)
Real-time average score tracking for promotion readiness
Dual summary modes for teacher-facing feedback and internal coaching
A multi-campus dashboard for performance trends and calibration
Custom rubric upload reflecting every domain of the Mastery evaluation system
"We didn't just want a faster tool—we wanted a smarter one. Swiftscore speaks our language now," said Margaux Munnelly.
"The coaching summaries and trend tracking are a game-changer. We can focus on growth, not just scores," added Heather.
Mastery leaders now use Swiftscore to support formal observations, informal walkthroughs, and coaching plan development. The results are tangible: write time has dropped by over 90%, feedback is now consistent across APs even across campuses, teachers see clearer and more actionable insights aligned to their growth goals, performance category eligibility is no longer hidden in spreadsheets but embedded in the dashboard, and instructional leaders now spend more time in classrooms rather than in documents. "We're seeing tighter language, faster turnaround, and better coaching conversations. It's everything we needed." "The feedback matches what we see—and says it better. I used to tweak every word. Now I copy and go," said Margaux.
We want feedback to drive development, not just data. Swiftscore helps us get there—with language we trust and time we can use.

Yes. Real-time average score tracking shows whether teachers are meeting advancement thresholds, for example 3.4+ for Advanced, instead of being averaged manually in spreadsheets.
