Best Teacher Evaluation Software in 2026: 10 Tools Compared

The best teacher evaluation software depends on which job you need done. Evaluation systems of record (Frontline, Vector Evaluations+, Education Advanced, iObservation) run formal cycles, forms, signatures, and compliance reporting. Observation and coaching platforms (Classroom Mosaic, Whetstone, TeachBoost, Sibme, Edthena) help leaders get into classrooms and run coaching cycles. AI feedback tools (Trellis, Edthena's Observation Copilot, and Education Advanced's new AI feature) help turn observation notes into feedback teachers use. Most schools need a system of record; the question is whether your bigger problem is the process or the quality and time cost of the feedback.

The Three Kinds of Teacher Evaluation Software

Two products can both call themselves "teacher evaluation software" and do almost entirely different jobs. Most buying mistakes come from not naming the job first.

1. Evaluation systems of record. These digitize the formal process: evaluation cycles, forms, rubrics, evidence, signatures, deadlines, and completion reports for central office. They are worth it when your pain is coordination and compliance across many schools or employee groups.

2. Observation and coaching platforms. These help leaders and coaches get into classrooms more often and organize what they see: walkthrough forms, look-fors, coaching cycles, and trend dashboards, sometimes built around video. They are worth it when you are building a culture of frequent observation and coaching.

3. AI feedback tools. These focus on the output: the written feedback a teacher receives. They draft framework-aligned feedback from an observer's notes, and the better ones connect it to the teacher's earlier observations. They are worth it when observations happen but the write-ups are rushed, generic, or eat your evenings.

In the UK and some other systems this category is called teacher appraisal software; the same three kinds of tools apply, with appraisal cycles in place of evaluation cycles. Districts that evaluate against a rubric (Danielson, Marzano, a state model, or their own) should treat rubric support as a must-have in every category.

The categories are blurring. Education Advanced has added AI drafting inside its evaluation system, Edthena offers a free AI write-up tool alongside its coaching products, and Sibme added an observations module with AI. Still, every product leans toward one job.

Comparison Table

For head-to-head detail: Trellis vs Edthena, Trellis vs Education Advanced, Trellis vs Sibme, Trellis vs Frontline, Trellis vs Whetstone, Trellis vs TeachBoost, and Trellis vs BloomBoard.

Evaluation Systems of Record

Frontline Education

Best for: districts that want evaluation inside a broader talent management suite.

Frontline covers the talent lifecycle: recruiting and hiring, absence management, professional growth, and evaluation. Its evaluation module lets districts configure rubrics, schedule formal observations, and track completion across schools, with reporting for central office.

• Strengths: breadth, integration with other Frontline HR products, established support.
• Watch for: the evaluation module is one part of a large suite; writing feedback is still largely on the observer.

Vector Evaluations+

Best for: districts that need configurable evaluation forms, cycles, and workflows.

Vector Evaluations+ (formerly TeachPoint) automates teacher and staff evaluations. Forms, workflows, and cycles can be set at the district, school, or user level, and it includes deadline dashboards, evidence uploads, video observation, and performance reporting.

• Strengths: configurability, evidence management, reporting across observations and summatives.
• Watch for: more configuration means more setup; plan for implementation time.

Education Advanced Evaluation

Best for: districts standardizing formal evaluation cycles.

Evaluation (which came to Education Advanced through its 2022 acquisition of Standard for Success) digitizes district-defined cycles: forms, walkthroughs and observations, evidence, goals, signatures, and completion reporting. Education Advanced has added AI-assisted feedback that drafts rubric-aligned comments from an evaluator's notes and can build summative narratives, with the evaluator approving every word.

• Strengths: a full system of record with AI drafting built into the existing workflow.
• Watch for: it is designed around the formal cycle; see Trellis vs Education Advanced for how it differs from a coaching-first tool.

iObservation

Best for: districts using the Marzano evaluation model.

iObservation, from Learning Sciences International, is built around the Marzano model, with observation data tied to the model's elements and a professional learning library connected to evaluation results.

• Strengths: deep Marzano alignment and connected PD resources.
• Watch for: less natural fit if you use a different framework or plan to switch.

Observation and Coaching Platforms

Classroom Mosaic

Best for: walkthrough data and trends across a school or district.

Classroom Mosaic supports observations, walkthroughs, learning walks, and evaluations with customizable forms, rubrics, scripting notes, and photos. Data aggregates automatically into dashboards that show trends across classrooms.

• Strengths: structured walkthrough data and school-wide reporting.
• Watch for: strongest at capturing and aggregating evidence; the narrative feedback is still yours to write.

Whetstone Education

Best for: networks built around frequent, brief walkthroughs.

Whetstone is popular with charter networks. Its mobile-friendly forms let leaders capture observations quickly, tag look-fors, and share feedback soon after a visit, with coaching action steps and dashboards alongside.

• Strengths: speed in the classroom and network-level visibility.
• Watch for: best when your model is many short visits; see Trellis vs Whetstone.

TeachBoost

Best for: structured coaching cycles.

TeachBoost (now part of EAB) helps leaders manage observations, coaching cycles, and teacher development, with configurable forms, pre- and post-observation conferences, and reporting on observation frequency and coaching activity.

• Strengths: configurable coaching workflows and a long track record.
• Watch for: configuration depth takes setup time.

Sibme

Best for: coaching programs centered on classroom video.

Sibme is an instructional evidence platform: teachers and coaches record and annotate lessons and run coaching cycles around them. Sibme Copilot analyzes evidence across observations, and a 2026 Observations module added synced notes and meeting summaries. Sibme also offers virtual coaching with expert coaches.

• Strengths: video, AI analysis across evidence, optional outside coaching.
• Watch for: video-centered workflows; see Trellis vs Sibme.

Edthena

Best for: video coaching, plus free AI help on observation write-ups.

Edthena's VC3 supports video coaching cycles, and AI Coach guides teachers through analyzing their own recorded lessons. Its free Observation Copilot drafts framework-aligned write-ups from a principal's notes, with the Danielson Framework for Teaching available through a partnership with The Danielson Group.

• Strengths: video coaching depth; a no-cost starting point for AI write-ups.
• Watch for: Observation Copilot works one write-up at a time; see Trellis vs Edthena.

AI Feedback Tools

Trellis

Best for: leaders who want to write better feedback in less time.

Trellis is built for the step after the classroom visit. Leaders add notes (typed, uploaded, or recorded as audio), and Trellis drafts positive-first, framework-aligned feedback (Danielson, Marzano, CSTPs, UDL, or custom rubrics). Each teacher has a growth profile, so drafts reference earlier observations and goals. Leaders review and edit everything before a teacher sees it.

• Strengths: speed, feedback that builds on each teacher's history, audio capture, transparent pricing, and a single school can start without a procurement cycle.
• Watch for: Trellis is intentionally non-evaluative. It does not manage formal evaluation forms, signatures, or HR timelines, so districts that need a system of record use it alongside one. It is also a newer company than most on this list.
• Pricing: Site plan at $249 per seat per year (or $39 per month) with unlimited teachers; custom District plan.

AI drafting also now appears inside Education Advanced Evaluation and as Edthena's free Observation Copilot, described above. The main differences among AI feedback tools: whether drafts draw on the teacher's history, which inputs they accept (typed notes, audio, documents), and whether the tool lives inside a formal evaluation workflow or alongside it.

What to Look for in Teacher Evaluation Software

Time from notes to finished feedback. Ask how long a complete write-up takes. If the tool only organizes forms, the hardest part (writing) is unchanged.

Feedback quality. Teachers can tell when comments are templated. Look for feedback that is specific to the lesson and connected to the teacher's goals. Our observation feedback guide explains what good looks like.

Framework support. Confirm native support for your framework (Danielson, Marzano, a state model such as T-TESS, or a custom rubric), not a workaround.

Teacher experience. What does the teacher see? A clinical, compliance-first experience undermines a growth culture.

Data privacy. Ask how teacher and student data is stored, whether observation content is used to train AI models, and whether the vendor signs a data processing agreement.

Reporting. District leaders need patterns across schools without exposing individual teachers unnecessarily.

Questions to Ask in a Demo

1. Show me the complete workflow from observation notes to feedback the teacher receives.
2. How long does a typical formal write-up take an administrator using your tool?
3. What does the teacher see, and when?
4. How do you support our framework, exactly?
5. Is our data used to train AI models? Will you sign our DPA?
6. What does implementation look like, and how long until our first observations?
7. What is the total annual cost for our number of schools, leaders, and teachers?
8. Can we pilot with a few leaders for one observation cycle?

Pricing: What to Expect

Most systems of record and coaching platforms use quote-based pricing, often per teacher and on annual contracts, so ask every vendor for a total tied to your staff count before comparing features. Edthena's Observation Copilot is free. Trellis publishes its pricing: $249 per seat per year with unlimited teachers for a school, or a custom District plan.

Switching Tools Without Losing a Year

• Decide what history you need. Ask how prior evaluations export and import, or whether a clean start is acceptable.
• Pilot first. Run one observation cycle with a small group of leaders before committing.
• Train on the workflow, not the features. Plan a short initial session and support during the first cycle.
• Explain the why to teachers. Focus on faster, more useful feedback for them.

FAQ

What is teacher evaluation software?

Software that helps schools run teacher observation and evaluation: scheduling and recording observations against a framework, producing feedback, and tracking completion. Products lean toward managing the formal process, supporting observation and coaching, or improving the written feedback.

What is the best teacher evaluation software?

It depends on the job. For district-wide formal evaluation, a system of record such as Frontline, Vector Evaluations+, Education Advanced, or iObservation (for Marzano). For frequent walkthroughs and coaching, Whetstone, Classroom Mosaic, TeachBoost, Sibme, or Edthena. For writing better feedback faster, Trellis.

Can AI write teacher evaluations?

AI can draft feedback from an observer's notes, aligned to a framework, much faster than writing from scratch. The observer should stay in control: reviewing, editing, and approving every word. AI is a drafting assistant, not a replacement for professional judgment.

How much does teacher evaluation software cost?

Most vendors quote per teacher or per district on annual contracts. Edthena's Observation Copilot is free. Trellis's Site plan is $249 per seat per year with unlimited teachers.

What's the difference between evaluation software and observation software?

Evaluation software usually covers the formal cycle, including ratings, signatures, and compliance. Observation software focuses on capturing what happens in classrooms, often during informal visits. Many tools do some of both.

What is the best teacher evaluation software for school districts?

Districts usually need a system of record for formal, rubric-based evaluations across schools, such as Frontline, Vector Evaluations+, Education Advanced, or iObservation for Marzano districts. Many add a coaching or feedback tool such as Whetstone, Sibme, Edthena, or Trellis for the informal observations between formal cycles. Trellis's District plan covers multiple schools on one agreement.

Is teacher appraisal software the same as teacher evaluation software?

Yes. "Appraisal" is the common term in the UK and some other countries for the same process: observing teaching, recording evidence against standards, giving feedback, and tracking growth. The categories and buying questions in this guide apply to both.

Is there free teacher evaluation software?

Edthena's Observation Copilot is free for drafting observation write-ups. Most systems of record are paid and quote-based. Trellis offers a 14-day free trial before the Site plan.

Do I need more than one tool?

Often, yes. Many districts keep a system of record for formal evaluations and add a coaching or feedback tool for the frequent, informal observations in between.
