DC uses a content-specific MAP test for science (life, physical or Earth and space science) but there is no percentile rank information available for these tests. I can see that physical science content for 8th grade is all mastered by a 260 but a breakdown of what each score means would be very helpful for reporting this information to students and parents. Telling a student they scored 210 is not as powerful as telling them they are in the 50th percentile.
