Type of school refers to whether the school is Elementary, Middle, or High School. In some cases a school has more than one type at its campus (for example a K-8 which is both an Elementary and Middle School). In the case that a school has more than one type, each type within that school will have its own grades and statistics. It is important to note that in the 2010 and 2011 data, the elementary and middle schools were combined so an elementary was compared to all other elementary and middle schools. However, in 2012, the data was separated out where elementary schools are only compared to other elementary schools. The same is true for middle and high schools.

According to the Colorado Department of Education, academic growth measures academic progress using the Colorado Growth Model. For an individual student, growth is a measure of progress in academic achievement in comparison to other similar students. For some states, this measure might simply be a change (a gain or a loss) in test scores from one year to the next. For Colorado, growth is not expressed in test score point gains or losses, but in student academic growth percentiles.
