Redistricting: Your School District


Who has to redraw their boundaries because of the Census?

Districts with director districts under §275.12 b-e

Each school district with director districts must file with the Secretary of State, County Auditor(s), and AEA the following, even if the school board does not make any changes to the method of election and/or director district boundaries:

  • School district worksheet prescribed by the Secretary of State’s Office

  • Director district maps

  • Certification of the population of each director district

  • Resolution adopting director district boundaries

If director districts are not changed, your CSD will have to prove analytically that "no change" is warranted; the district still needs to go through the redistricting process.



How is redistricting done for school districts?

Following are the step by step requirements school districts must meet in redistricting director districts. After the code explanation a hypothetical example is provided to see the software and understand the decisions to be made.

275.23A  Redistricting following federal decennial census.
School districts which have directors who represent director districts as provided in section 275.12, subsection 2, paragraphs “b”, “c”, “d”, and “e”, shall be divided into director districts according to the following standards:


An Example of Our Redistricting Service

Jim has a fondness for Mount Vernon as he attended Cornell College. So for this scenario - which is completely hypothetical - Mount Vernon has been chosen. The data used are all the correct type of data, though they are outdated.

Readers should note the irregular shape of the Mount Vernon school district. School districts due to their organic growth and definition of boundaries are irregular compared to counties or legislative districts; hence, it is difficult to argue compactness when director districts (DDs) are drawn.

The most DDs a school district can have is seven, and we'll use that number in this example.

Further note the map's legend. There are four relevant layers - the school district, cities, precincts, and census blocks - with 296 polygons in total to consider.

With seven director districts in the example that means the ideal director district size would be 794.  Therefore, the city of Mount Vernon must be divided into director districts.

Mapping Strategies uses ESRI products and this is a districting module extension running with ArcGIS.

The screenshot captures three other very important aspects:

  1. See the summary statics, which are required and necessary for calculation;
  2. Another window shows the attribute database associated with the map;
  3. The previous described features and the interface demonstrate the ability to recalculate on the fly and consider different scenarios.


Assigning Territory to Director Districts

Geographic Information Systems (GIS) allow for:

  • Simultaneous consideration of all redistricting factors
  • Iterative analysis allowing for strategic scenarios
  • In this scenario consideration is being given to dividing the school district population by mixing rural and urban areas of keeping them separate.
  • Statistics for plan justification deviation and percentage deviation
