Do colleges know if we're in the top 10% of our class even if my school doesn't rank?

@me29034 , no high schools where we live rank, and I think this might be true of many schools with highly competitive students. Our school doesn’t rank for this reason. A college looks at the profile of the school, what classes are offered, and a range of other stuff. Example, my D has good grades, but not 4.0. Many of her classmates have a higher GPA, but guess what? Those kids are doing regular classes, while my D is taking 4 APs. This is why ranking is not an effective tool. A better use of,the school profile is to see where my daughter falls within kids who have similar course loads to her. If there was a big discrepancy between her and the valedictorian with grades, and the V is taking classes similar to my kid (which I happen to know she is), that would cause concern. But if the all the top kids have roughly similar grades in tough clases, the college knows the school probably isn’t inflating grades. Ranking is useless.
