NAVY SCHOOL MANAGEMENT MANUAL

To determine what is minimum passing on a test, the
SMEs decide which test items the student must answer
correctly to indicate minimum acceptable performance.
This number is called the minimum passing raw score.
The minimum passing raw score will vary based on the
content of the material. Example, material that is
most critical may have a higher raw score than less
critical material.
Translation of the Raw Score on a Knowledge Test to a
Grade:
Step One: Determine the raw score for the minimum
acceptable performance on a test. The minimum is always
equal to 63 (the minimum passing grade on the scale).
Step Two: Calculate the grade equivalents for the
remaining scores above 63. For example, you have
determined that the raw score for the minimum acceptable
performance on a test is 30 of the 50 items.
Subtract the minimum grade from 100.
100 – 63 = 37.
Subtract the minimum raw score from the total items.
50 - 30 = 20
Divide the remainder of grade points by the number
above raw score.
37 ÷ 20 = 1.85
Add 1.85 to all grades above 63.
