Case Study: Kodilla achieves 50% grading cost reduction and 95% automated test grading with DevSkiller

Coding bootcamp Kodilla cut the cost of grading their tests by 50% and added 4x more new tests

Kodilla is a Wroclaw-based coding bootcamp that trains Java and web developers and helps graduates find their first IT jobs. Facing slow, error-prone manual grading (mentors spent about 30 minutes per student using Google Forms), Kodilla needed a way to scale assessments and free up time for product development, so they adopted DevSkiller’s automated coding-assessment platform.

By using DevSkiller to grade tests automatically, Kodilla cut grading costs by 50%, added 400% more new tests, and now has 95% of tests graded automatically, allowing them to assess 100+ remote students per month. Grading time fell from 30 minutes per test to 0 minutes for 95% of cases and 5–10 minutes for the rest, boosting employee and student satisfaction and enabling faster product development with DevSkiller.
