Through anonymous surveys I took last year I've found that scholarships are exclusively tied to SAT scores but vary greatly based on what school you're in. My poll last year was exclusively for students whom took the older version of the SAT and I found that the average SAT score for a (3,500-7000) scholarship is 2140. I'm not sure what the conversion on that would be. The average score for the next 'tier' (10,000 - 17,000) was a 2230. Then finally the highest tier (22,000-26,000) had an average SAT of 2350. Extracurriculars and class rank (NOT GPA) play a role in where you're stratified. For example, if you get a 2350 on your SAT and aren't in the top 15% of your class, you'll get no scholarship. Conversely if you're in the top 1% of your class and don't have a minimum of a 1950 SAT score you'll receive no scholarship. Scholarship profiles are further stratified based on extracurriculars and the 'fit' you have for a given school. So for example I had some students perform better academically than another student attending the business school. Lets call them students A, B and C. Students A and B both had SAT scores in the 2300s. Student C had an SAT score in the low 2200s. Student C received $22,000 to attend whereas students A and B were given 13,000. As it would turn out, student C had more leadership position extracurriculars than the other students and thereby was knocked up a tier.

As you can see, it's a very complex and overly convoluted system that leaves a bunch of people scratching their heads. Prior to 2010, Rutgers had a matrix of scholarships that were given to students irregardless of school choice. It was automatic and solely based on your class rank and SAT/ACT score. The best advice I can give you nowadays is to shoot for as high as possible and represent yourself the best you can. There are some insane outliers I found that are frankly extremely unfair.
