Hi Lee, I moved your post to its own thread. Please start a new thread when you ask a question. :-)
So you want to write the essay in a way that highlights the fact that you have a Cisco Network License?
At the start of the essay, you could do something like this:
The most important achievement of my education occurred on October 10, 2010, when I was awarded my Cisco Network Certificate.
You can highlight this fact by putting it at the beginning of a paragraph or even at the beginning of the whole essay. The way to highlight it is to put it in the right place in the essay.
Why do you want to highlight the certificate instead of some other accomplishment?
