Often, colleges will ask you what quartile you are in, or you may need it to see if you qualify for automatic admission into that university. See the information below for a quick and easy way to understand and calculate what quarter you fall in.
Quartiles are 25% segments (Think quarters)
25% - 1st quartile
50% - 2nd quartile
75% - 3rd quartile
100% - 4th quartile
When you are given your class rank, divide it by the total number of students in the class.
For example, If a student is number 322 out of 552, they divide 322/552 = .58 or 58% (3rd quartile).
