Technology to support teachers

Educator evaluations are contentious and cause administrative strain. They are disconnected from teacher professional development and exist in an environment of evolving standards.

That’s why we created Whetstone

A flexible and adaptable tool to capture, organize, and analyze teacher performance. Our system allows for transparency when needed and permissions when appropriate.

Our Solution Is As Unique
as Your Students


We work hand-in-hand to develop a user friendly and comprehensive software solution that meets the needs of your organization’s existing (or desired) evaluation process.


Throughout the course of the school year we discuss with you how to make the system more impactful to better meet your needs by seeking feedback, adding new features, and improving functionality.
