What is technical writing?

Technical means that something is in a particular format; it is something that you are specifically trained for. Writing is when words and thoughts are transcribed either electronically or onto paper. Technical writing is writing professionally, to a specific audience, with a particular purpose. I feel like this can mean something different in my particular field even though there are undeniable similarities in every field. It can involve emails or memos to other faculty and staff members along with parents, there are also letters or newsletters to be set home. As a member of the education field my technical writing can also involve the way that information is presented to the students and even the lesson plans that I will have to create. Personally technical writing so far does not include much of the above. Most of the writings that I have to do are done for no other specific audience except the teacher and do not have an extremely specific format, they are only essays.
