Determinations for Administrative Units (AUs)

Starting in 2017, the Colorado Department of Education Exceptional Student Services Unit (ESSU) is using both compliance and results matrices to make determinations for each Administrative Unit (AU) under section 616(d) of the Individuals with Disabilities Education Act (IDEA). Using the Result Matrix developed by the Result Matrix Workgroup and the preexisting Compliance Matrix, we consider the totality of the information we have about an AU.

Please see the resources below for more information about AU Determinations.

Important Note: Each Administrative Unit (AU) operates within a unique context.  Questions about the information contained in the Determination Matrix are to be directed to the AU Director,


If the visual nature of the AU Determinations below is not accessible to you, or if you would like to explore all the data in one place, the full data set, including all Administrative Units, can be found in the Excel file below with the corresponding year.

Please Email Gloria Durosko (Supervisor, Data and Monitoring Liason) with questions.
