About us

Helping educators and students

CodeGrade started as a university project at the University of Amsterdam to make our lives as TAs for coding courses easier, and for students to get the feedback they need to be successful in computer science education. Today we are helping universities, companies, bootcamps and high schools around the world to make their programming education better.

We want to
Help every coding educator maximize their teaching performance, so their students get exceptional education.

This drives us to
Create the best platform for coding education.‍

History and future of CodeGrade

Our story

2015
Students Computer Science
In our introductory programming courses, we had to wait weeks at times to get very brief feedback on our assignments.
2016
Grading workload as a TA
As teaching assistants in various programming courses, we found that the workflow was inefficient and did not allow us to spend the time to give students the feedback they required to improve. This motivated us to develop CodeGrade to improve this workflow.
2018
CodeGrade established
We further developed CodeGrade to improve the marking and feedback workflow, with funding from the University of Amsterdam and collaboration with professors in the institution. By 2018, we officially established ourselves as a spin-off of the UvA.
2019
Going worldwide
With a highly improved product which features included inline comments, LMS integration, advanced autotests and rubrics, we rolled out CodeGrade to the rest of the world.
2021
50+ Universities with 750k+ graded assignments
From only 2 universities in 2018, CodeGrade has now been adopted by over 50 universities. Together with them we have (auto) graded more than 750k assignments.
