Both the job duties and goals will be rated during the evaluation phase of the review cycle. If you copy your job duties into your goals then you will be rated twice on the same responsibility. You should ensure that responsibilities are not combined into one job duty/goal so that each has its own measurement describing what it means to meet the expectation for that job duty/goal and so that each can be rated separately.
As a best practice, we recommend that you not only define what it means to meet each responsibility but what it means to be exceptional.
