Best Teacher Observation Software for Schools
By Justin Baeder, The Principal Center — Updated April 2026
Teacher observation software ranges from simple digital forms to comprehensive platforms managing the full evaluation lifecycle. As a principal who has used several of these tools and interviewed dozens of instructional leaders about their observation practice, here's what actually matters — and what's just features that sound impressive but add friction.
Disclosure: Repertoire is built by The Principal Center. Other tools are independent products reviewed on merit.
Best for Informal Observations & Feedback
Repertoire
The feedback-focused walkthrough app for principals
Most principals do many more informal visits than formal observations — and most of those visits never result in written feedback. Repertoire is built specifically to close that gap. It makes sending a personalized feedback email fast enough that it actually happens, rather than getting pushed off until tomorrow (which becomes next week, which becomes never).

Repertoire

Where most teacher observation tools focus on formal evaluation documentation, Repertoire focuses on what actually drives teacher growth: frequent informal visits and fast, personalized feedback. The snippet library lets principals compose professional, specific feedback in under a minute — then send it from their own email address, so teachers get a message from their principal, not a system notification.
Pre-built snippet collections for Danielson, Marzano, and other common frameworks come built in. If your district uses a custom framework, photograph the rubric and Repertoire imports it automatically.
Who it's for: Individual principals and instructional coaches who want to dramatically increase their feedback-to-visit ratio without adding time to their day.
Frontline Evaluation

Frontline is one of the most widely deployed HR and evaluation platforms in K–12 districts. Frontline Evaluation handles formal observation cycles, goal-setting, and summative ratings — and integrates with Frontline's broader HR suite including absence management and hiring. The integration story is its main selling point: one platform for the full HR and evaluation workflow.
Who it's for: Districts already using Frontline HR tools who want to consolidate evaluation documentation in the same system.
The DIY Problem (Google Forms)
Why free tools usually fail
Many schools try to build walkthrough systems with Google Forms or Sheets. It feels like a free solution — and it is, until you calculate the administrative time involved in managing data, building reports, and chasing down feedback that never gets written.
The deeper problem: a Google Form doesn't help you write better feedback. It just collects data. Purpose-built tools like Repertoire are worth the investment because they solve the actual bottleneck — the writing.
Frequently Asked Questions
Should I use the same tool for formal evaluations and informal walkthroughs?
Not necessarily. Formal evaluation tools are built for documentation, rubric ratings, and legal defensibility. Walkthrough tools are built for speed and feedback. Many effective principals use a district-mandated formal evaluation platform alongside a personal walkthrough tool like Repertoire.
What framework does Repertoire support?
Repertoire includes pre-built snippet collections for Danielson (Framework for Teaching), Marzano, and other common state and national frameworks. You can also photograph any custom rubric and Repertoire imports it as a snippet collection.
How many classroom visits should a principal do per week?
Research consistently points to 2–3 visits per teacher per year as a meaningful minimum for informal walkthroughs with feedback — though more is better. The binding constraint isn't usually time in classrooms; it's the time it takes to write up and send feedback. Solving the feedback bottleneck is the key to increasing frequency.
