Mobility/Stability Statistics for 2011-2012

The 2011-12 school year marked the sixth year in which the Colorado Department of Education calculated and reported student mobility rates. These rates have been reported following the guidelines set forth in CCR 301-67 - “Rules for the Administration of Colorado Data Reporting for School Accreditation.” In addition, this year the state began reporting stability rates. The stability rate represents the number and percent of students who remained at a school/district without interruption throughout the school year. A more in-depth calculation is provided.
