  4. Percentiles • This type of score comes from a comparison of a student’s score to other students’ scores in a norm group (group of students being tested). • Example: If a student scores in the 75th percentile this means that this student preformed better than 75% of the students in the norm group.

  5. Percentiles Still not making sense? Let us look at it from a different angle. • If the student scored in the 75th percentile only 25% of students in the norm group preformed just as well or better than this student. • Another way of putting it is that this student is in the top 25% of the norm group.

  6. Percentiles Biggest Advantage Typically understood by most of the general public and parents. Biggest Disadvantage Scores are dependant on the quality of the norm group.

  7. Discussion Questions/Comments about Percentiles

  8. Grade-Equivalent Scores • This score is an indicator of student test performance based on grade level and months of the school year. • Example: a student who scored a 7.3 on a mathematics test would be function in this subject like an average 7th grader in their 3rd month of the school year.

  9. Grade-Equivalent Scores Still not quite making sense? Grade 7.3 Month
