I’m not sure that a scholarship would mean much in the admissions process. The accomplishments/awards/efforts that went into garnering a scholarship should be the inputs to the application.
The analogy is being an AP National Scholar. The title itself is meaningless, but the AP scores the serve as qualification for the award may (or may not) be what’s meaningful.
There are so many awards out there that listing and quantifying them would be an endless exercise. An IMO Gold Medal would be beneficial to college admissions. A high school “prettiest eyes” award wouldn’t.
There’s a very long thread here on CC somewhere that attempted to list a bazillion awards/accomplishments and rate their impact on a 1-10 scale. The accuracy/value of such a list is debatable, but it at least provides a long list and the input of many, many CC’ers to your question.
