Neighborhood Factors - Sources and Methodology

Student-level enrollment and home addresses: SY2013-14 through SY2018-19 OSSE Audited Enrollment. The following audited enrollment business rules were applied to the audited enrollment files for SY17-18 and SY18-19: 1) The universe of DCPS students include audited UPSFF residents + Non-resident tuition paying +  Residency unverified and 2) The universe of public charter students include audited UPSFF residents. Student level data was geocoded by the Office of the Chief Technology Officer with all District-appropriate neighborhood geographies appended to each student. Home addresses reflect students’ residences provided at the time of registration. Registration can occur between the spring prior to the start of the school year up until the enrollment audit, approximately October 5th of the current school year. The student yields exclude non geocoded students or those students that could not be assigned a ward or neighborhood cluster.

Property information: “Apartments – DCHA” represents apartment units in the 56 public housing sites owned and managed by the District of Columbia Housing Authority (DCHA). These were identified geographically and not from the tax rolls nor DCHA administrative records. Because they tend to have substantially higher numbers of students enrolled in public schools, these properties are disaggregated from all apartments in several charts in this chapter.

Residential pipeline information: DC Real Property database and DC Policy Center public data, DMPED Real Estate Project Pipeline Database (PPD), Washington DC Economic Partnership (WDCEP)

Calculating student yield in future residential properties: for the Noyes ES boundary example, we applied the Ward 5 student yields per property type to the number of units in the residential pipeline for the boundary. For units of unknown type, we used the proportion of “known” unit types. 

Calculations to estimate Noyes ES potential new students

  • Student Yield per 100 Units - Ward 5
    • Apartments - 35 students
    • Condos - 15 students
    • Single Family  - 40 students
  • Near term (2020-2021):
    • 413 rental units/100 = 4.13 * 35 =  145
    • 131 single family units/100 = 1.31 * 40 = 52
  • Long term (2025-2031):
    • 1,329 rental units/100 = 13.29 * 35 = 465
    • 114 condo units/100 = 1.14 * 15 = 17
    • 2,138 unknown units
      • 92% rental: 1,967 rental/100 = 19.67 * 35 = 688
      • 8% condo: 171 condo/100 = 1.71 * 15 = 26

Early Development Instrument (EDI): The EDI is an internationally validated tool that provides information about school readiness for the District’s 4-year-olds in all eight wards.  This information was collected from 116 schools and 340+ classrooms during SY2016-17 and will be administered again in February-March 2019.
