Codio & Masterschool
A flexible and powerful basis for teaching
“One of the principles we believe in is that to be a good developer, you need to just code a ton. This is why we make sure our students code in every learning page and hand in a project every week, which gets reviewed by an actual human software developer.”

What we needed
Why we chose Codio
Masterschool evaluated several platforms, including GitHub Classroom/Codespaces, but needed an all-in-one solution that merged grading, feedback, and environment consistency:
Teaching with Codio
Courses Taught With Codio
- Python Fundamentals: Core weekly projects
- Java & Linux: Introductory and intermediate exercises
By standardizing on Codio:
- Submissions & Grading are centralized, reducing friction and confusion.
- Collaborative Feedback is straightforward, with direct commentary in the student’s code.
- Environment Mismatches are eliminated—all projects run identically within Codio.
Seamless Environment for Large-Scale Feedback
Working with Codio
- Dedicated Support: Fast turnaround on questions or feature requests.
- Technical Expertise: Smooth LTI integration with Masterschool ’s systems.
- Active Collaboration: Regular communication to address ongoing needs, ensuring a robust and reliable workflow.
Communication with the Codio team is great—questions are answered super fast, and the support is always there.
Going forward
Masterschool ’s journey with Codio will continue as the network explores additional technical tracks—potentially covering more languages, data-focused lessons, and advanced development topics. Maintaining a single, user-friendly submission and feedback platform is key to Masterschool ’s mission of preparing learners for real-world development roles.
