 Define:
 X = the mean raw score achieved on the new test form's scorable items based on response data from the parent form (Y)
 s_{x} = the standard deviation of the scorable items on X based on response data from the parent form (Y)
 Y = the mean raw score achieved on the parent test form's scorable items
 s_{y} = the standard deviation of the scorable items on Y
 X_{i} = a given raw score on the new test form
 Y_{i} = the raw score equivalent to X_{i} expressed in the raw score metric of form Y

Set z_{x} = z_{y}
 In order to find the equivalent raw cutscore on the new form, solve for X_{i}, where Y_{i} = the raw cutscore on the parent form rounded to one decimal place.
X_{i} = X + (s_{x}/s_{y})(Y_{i} − Y)
