C# Coding Apprentice (CCA)

Candidates are expected to demonstrate a general background in coding with C#. Prior to taking the exam, a candidate is expected to have approximately 100 hours of hands-on experience or lectures on developing using C#.

The elevated level of preparation required is derived from the industry-standard level of the exam and the fact that this certification reflects the candidate’s readiness to enter the job market. Moreover, this Certification is used as a job placement index by recruiting managers, for the correct placement of a job seeker. Knowledge Pillars CCA uses a task-based format in order to ensure the validity of the results.

To optimize the examination experience for the Candidate, Knowledge Pillars has taken certain steps to utilize a real C# coding environment during the examination. The exam is provided both in Testing Centers or remotely, via the remote proctoring system.
