The General Coding Assessment (GCA) is the only certified assessment that can be retaken. However, like other standardized assessments, there is a limit to how many times one can retake the assessment within a given time period.
We believe that 14 days gives enough time for candidates to up-skill between attempts.
You may retake the assessment on CodeSignal once 14 days have passed since your last test session and provided that you receive a new invitation from another company.
