The Problem

School leaders spend nearly 10% of their time each week managing the mountain of paperwork that comes from teacher observations and feedback. In many schools, observation data is scattered across spreadsheets, emails, word documents, and Post-It notes, making it difficult to share feedback and analyze trends.

Schools spend hundreds of hours a year tracking down teacher performance data across paper forms, shared drives, spreadsheets, and email. Leaders need one place to take notes, share feedback, track goals, and analyze trends so that they can spend more time with teachers and students and less time managing paperwork.

Without data, school leaders provide professional development to teachers based on a hunch. When PD is not aligned to a teacher’s unique professional growth needs, teacher satisfaction goes down. School leaders should have an easy way to see a teacher’s growth areas and strengths in order to personalize professional development.

Thirty three states require annual reporting of classroom observations and evaluations. School leaders must report teacher observation data to both districts and states in order to remain in compliance, and they deserve a platform that makes it easy.

Our Solution

We built Whetstone to make classroom observation easier and simplify data analysis so that school leaders can provide data-driven professional development to their teachers. Whetstone streamlines observations with a one digital home where leaders can take observation and meeting notes, share feedback with teachers, set goals, and analyze teachers' needs and growth.

Our Story

Like most good ideas, Whetstone was hatched over lunch. In a humid New Orleans cafeteria in 2011, two school leaders were commiserating about the inefficiencies of their teacher coaching process. There were binders full of rubrics, drives full of forms and trackers, and multi-year email chains with action steps and accolades. No systems talked to each other; reporting was a nightmare. That night, Andrew Cox went home and wrote the original code that is the backbone of Whetstone’s classroom observation and coaching platform. Today, Whetstone’s technology supports both Teacher Coaching and Teacher Evaluation at more than 300 schools across the United States.
