    I am a Marketing Specialist, also very skilled in WordPress. I often handle and manage content and create powerful pages and messages in the WordPress editing environment. I spend 50% of my time working in WordPress and I have always been concerned about my lack of credentials for this powerful and largely used software.

    I’d like to outline or prove my skills in some way so that I may improve my career, increase my value in the market, and chances of getting a higher salary. The Knowledge Pillars WCE certification addresses this need, it offers a new, innovative and powerful means to prove my skills in a practical way by showing concretely my ability to manage, build and edit in a WordPress environment.
