originator mapDigital Geverdt, D, (2015). Documentation for the School Attendance Boundary Survey: School Year 2013-2014 (NCES 2015-118) U.S. Department of Education. Washington, DC: National Center for Education Statistics. The School Attendance Boundaries Survey (SABS) was an experimental survey conducted by the U.S. Department of Education’s (ED) National Center for Education Statistics (NCES) with assistance from the U.S. Census Bureau to collect school attendance boundaries for regular schools in the 50 states and the District of Columbia. Attendance boundaries, sometimes known as school catchment areas, define the geographic extent served by a local school for the purpose of student assignments. School district administrators create attendance areas to help organize and plan district-wide services, and districts may adjust individual school boundaries to help balance the physical capacity of local schools with changes in the local school-age population. The SABS collection includes boundaries for more than 70,000 schools in over 12,000 school districts throughout the U.S.All information contained in this file is in the public domain. Data users are advised to review NCES program documentation and feature class metadata to understand the limitations and appropriate use of these data. This layer provides public school attendance area boundaries for the 2013-2014 school year created by the National Center for Education Statistics’ (NCES) Education Demographic and Geographic Estimate (EDGE) program.

School feeder 'slivers' remain in these areas. The map only includes information provided by the district. Every effort was made to ensure that all populated areas were covered by school boundaries, but in some instances 'Unassigned' polygons cover populated Census blocks. Data were collected by the Census Bureau’s Economic Reimbursable Surveys Division and the National Processing Center. The data were processed by Sanametrix on behalf of NCES. School districts were contacted directly and invited to participate in the survey. In most cases, the district provided the data directly to the SABS staff, but in some instances, the data were provided by the local county or a private consulting firm. Delaware, Minnesota, and Oregon provided statewide data sets. Project into processing geodatabase. 2015-01-05T00:00:00 Merge School Level Feature Classes: Merged all applicable school level feature classes, such as primary, middle, and high, into a new single feature class. 2015-01-12T00:00:00 Fuzzy Join by Level: Uses fuzzy string comparison to append a field from the Join Feature Class to the Target Feature Class. Candidates for the match are limited by a where class. 2015-01-19T00:00:00 Verify School Completeness by District: This tool uses the NCESSCH attribute to check for duplicate IDs, valid IDs, and it checks for missing schools. 2015-01-26T00:00:00 Assign, Dissolve, Append, and Join: Brings together the feature class that contains the school attribute details and updates them with their most current boundaries. The Dissolve operation is used to extract each level of school boundaries and transforms them into a multipart polygon. Next, the extracted features are merged through the Append operation. Since the Dissolve operation will remove the attributes of the data, a Join operation is performed as the last step to restore these attributes by joining the merged features with the original multipart school feature class. 2015-02-02T00:00:00 Union, Clip, Union, and Multipart to Singlepart: Unions all levels of school boundaries together, then clips them to their district boundary. The final step unions the clipped boundaries to the district boundary. 2015-02-09T00:00:00 Add Required Fields: Automatically copied attributes from fields provided by the school district into SABS schema. This tool also added and populated SrcLvel and LEAID.Unnecessary fields were deleted during this step. 2015-02-16T00:00:00 Geometry Tolerance Check: Compares dissolved school boundaries with the Census School District Boundary and identifies non-identical areas greater than the default minimum tolerance of 0.001 meters. 2015-02-23T00:00:00 Add Boundary IDs: Calculates the BdyID field to ncessch +01, then +02 for the second boundary of the same school, +03 for the third boundary, etc. Tool will also populate: contactID- 999999 updateDate- now() stAbbrev- two character limit boundary_complete- Y/N 2015-02-23T00:00:00 Spatial Check for Missing Grades: This tool uses the CCD and a single district feature class to find geographic areas that are not covered by a specific grade range. 2015-03-02T00:00:00 The SABS dataset is intended for research purposes only and reflects a single snapshot in time. School boundaries frequently change from year to year. To verify legal descriptions of boundaries, users must contact the school district directly.
