Data-Driven Teacher Development


Whetstone is a ridiculously easy, customizable classroom observation platform that enables schools and districts to grow their teachers through feedback. Stop struggling with spreadsheets and expensive, clunky evaluation platforms. Put your observations, weekly meeting notes, and action steps in one place!



Whetstone gives schools and districts one digital home to take time-stamped observation notes, fill out forms and rubrics, plan meetings, track action steps, and share feedback in real time.


Whetstone’s communication tools make it easy to share data and feedback with the right people at the right time, and help leaders and teachers work collaboratively toward instructional goals.


Whetstone’s built-in reports make it easy to see teachers’ growth needs so that leaders can provide targeted coaching and data-driven professional development sessions.





As an instructional leader, you’re dedicated to helping your teachers improve their practice. But it’s easy to lose track of which teachers need support with what growth areas, when you’re busy putting out fires and juggling the tasks on your endless to do list. Whetstone can help you and your team put everything related to classroom observation in one place with smart analytics, so you can get into more classrooms and have more data-driven coaching conversations to help you hit your school growth goals.



Managing classroom observation and teacher coaching data for one school is hard -- multiply that by 20. Or 50. Or 100! With the time and resources invested in developing a district-wide coaching system, it’s critical you have an efficient way to show its impact. Whetstone gives you access to coaching and evaluation data across ALL of your schools, as well as operations and central office staff, making it ridiculously easy for the Academics, Data, and HR Teams to pull pertinent data at the end of the year.



Building capacity into school leaders is a critical part of building a culture of coaching in schools and districts. However, helping leaders coach their teachers is hard -- especially when you can’t be in the building every day. Whetstone helps organizations like Relay GSE, Teach For America, New Leaders, and Leading Educators capture data when they’re in schools, collaborate virtually when they’re not, and see trends across all partners to better refine programming and support.

Organize your data. Coach your teachers. Grow your school.
