The performance categories are determined by cut scores which can be set for the school or district from a School Administrator or District Administrator account. The color of each score is based on the percentile of the score. For example, based on the default settings, if a student scores in red it means that the score is below the 26th percentile. If a student score is in green it means the score is above the 60th percentile. The default cut scores for the performance categories can be customized for your school or district.
In order to save your changes there can be no gaps between the high number of one row and the low number of the row above it.
