When calculating average improvement of students do you take the average of all improvement percentages or do you average all pre-test scores all post-test scores and then calculate the difference?

I was given this formula in college:

IND Posttest score - IND pretest score

______________________________ = Improvement Score

Highest score for all - IND pretest score
