Percent of Increase

  • To determine the percent of increase you must know the starting score which the student attained on an assessment and the score which you want the student too attain on the next assessment.

The percent of increase can be determined by finding the difference between the two numbers (55 – 15 = 40), then dividing by the original number and multiplying by 100 (40/15 = 2.66 * 100 = 266%) the student would have to increase their score by 266%.
