From the Global Report website:
"The GRC score indicates the level of math or reading achievement by the average student in a public school district compared to student achievement in a set of 25 developed countries. The score represents the percentage of students in the international group who would have a lower level of achievement. For example, a percentile of 60 means the average student in a school district would perform better than 60% of the students in the international group."
