How Are ITBS Scores Calculated?

The ITBS test has four types of scores:

  • Standard Score (SS). Raw scores are converted to Standard Scores, ranging from 80 to 400. The Standard Score is used to describe student’s location on an achievement continuum.
  • Grade Equivalent (GE). Grade Equivalent scores represent the score that the average student in the indicated level would achieve if given the test. Scores range from k.0 to 13+, with the decimal indicating month of the school year. For example, 2.4 means the fourth month of 2nd grade. The Grade Equivalent scores allow for comparison of growth over time.
  • National Stanine (NS). National Stanine are a very broad, simplified scores that ranges from 1-9, with 9 being the highest possible score. This score is also normalized for both age and grade groups.
  • National Percentile Rank (NPR). The National Percentile Rank score is used to compare students to other students in their age and grade. A percentile rank of 80 means that a student scored better than 80% of students who took the test. A percentile rank of 50 is considered average.
