Many IT professionals begin their careers in IT support-related positions. The main purpose of the TestOut PC Pro certification is to verify necessary skills to work as an IT support professional. In an IT support job, you’ll be asked to install, repair, configure, secure, and manage computer hardware, operating systems, and software in home or corporate environments. These are the most basic and foundational skills required of all IT professionals. Additionally, communication, listening and analysis skills are essentials for interacting with customers.
