Objective Statement. The objective statement is somewhat antiquated since online applications have evolved. Unless you’re sure that your resume is going directly into the hands of the hiring manager or recruiter, an objective statement is not necessary. If you like the idea of an objective statement, consider adding a professional summary statement instead. While an objective statement explains what you hope to accomplish, a summary statement explains who you are and what you have already accomplished. It also positions you to be desirable to the company, rather than seeming like you are only looking out for what YOU want.
In the United States, a CV is almost exclusively limited to professions in academia, science and medicine. In the case of academia, the main focus of the CV should be to identify yourself as a scholar. The added length, should be filled with proof of your skills as a teacher, scholar, and your knowledge of education. A CV should be thought of as a living document, and it will change frequently based on the updates in your education and career.
