I have heard the RHCE Exam described as “performance-based”. What is meant by “performance-based” certification or “performance-based” testing?
The RHCE exams are performance-based in two very specific and important senses. First, the actual performance of candidates is tested by requiring them to successfully complete installation, configuration, troubleshooting, and maintenance tasks similar to those they must complete on the job as system administrators. Second, Red Hat determine their performance on these tasks by whether their systems perform as specified in an objective and verifiable manner.
