You never get graded in the real world. That may sound good except that what happens instead is that you get judged behind closed doors and you never definitely know what people thought, you just see a consequence, like, "you get fired." While great leadership can clarify what is going on, they can't fill every gap. An organization may set a lower bar than what you're capable of; do you just aim for that, or do you try to go farther? If you do farther, will you get a jealous backlash from coworkers? Everything is contextual, and office politics often rope you into the hot seat. So the only way you can definitely "know how you're doing" and not become an anxious mess is to work towards developing your own grading system, with your own rules, principles, and standards. You don't have to rush it - you have your whole career to perfect that system, but it's actually the basis of how you operate, and not whatever specific thing you've been hired for or assigned to.
