Combined Percentile Index

Figure the class rank percentile by dividing class rank by class size, then subtract that percentile from 100 percent.

Using the Test Score Percentile Chart given below, find the appropriate ACT/SAT composite test score percentile.

Add it to the class rank percentile to get the Combined Percentile Index.

For example:

 

Class Rank = 6 

 ACT Composite Score = 19

Class Size = 30

 ACT Percentile = 42

1 - (6 divided by 30) = .80 or 80 percentile

Class Rank percentile = 80 percentile

Combined Percentile Index = 80 + 42 = 122

Combined Percentile Index of 122 exceeds the minimum combined percentile index of 100, so the student would be admissible to Northwest if core curriculum and GPA requirements were met.
