By default, all tasks in a test that you create in Codility have the same weight. This means that if your test consists of 2 tasks, the final score is calculated based on how the candidate performed on each task with equal weight - 50% for the perfect solution in task 1 and 50% for the perfect solution in task 2. However, if you prefer to assign a different number of points to different tasks, you can do it by using Weighted Scoring.
How do I enable Weighted Scoring?
You can enable weighted scores when creating a test:
Please note that once your test is in use, meaning that there is at least one session created for it, there is no option to switch off weighted scoring. Similarly, if your active test was created without weighted scores, you won't be able to adjust it - the only option is to duplicate the test.
Once the weighted scoring is enabled, it will also be reflected in your candidate reports:
How does it look for my candidates?
When candidates start solving a test that has weighted scores, they are informed about this through prompts in the UI so they could allocate their time the way they see fit:
Weighted Scoring is available to all clients on Codility Growth Plan or higher. Interested in Weighted Scoring but you don't have this feature enabled? Contact your Customer Success Manager or email@example.com - we will be happy to help!
