Student Generation Rate Study Everett School District March 24, 2000 This document describes the methodology used by the Everett School District to calculate student generation rates (SGR's) for three types of residential construction: Single family detached, multi-family with 0-1 bedroom, and multi-family with 2 or more bedrooms. Condominiums, townhouses and duplexes are included in the multi-family classification since they are not considered "detached", and mobile homes are included in the single family classification. 1. The District obtained computerized records from Snohomish County containing data on new construction within the Everett School District from January, 1992 to June, 1999. This data was extracted from MetroScan files by the County, and provided to the District in Microsoft Excel format. As compiled by MetroScan, this data included the address, building size, assessed value, year built, and plat name of all parcels with improvements built during the indicated time frame, including new recorded plats and shortplats, new single family construction on unplatted/acreage accounts, new multi- family residential construction, and non-residential construction. The data was "cleaned up" by eliminating records which pertained to non residential projects and those which did not contain sufficient information to generate a match with the District's student record data(i.e. incomplete addresses). 2. The District downloaded data from the computerized Pentamation student records system into Microsoft Excel format. This data included the addresses and grade levels of every student attending the Everett School District as of March 17, 2000. Before proceeding, this data was reformatted and abbreviations were modified as required to provide consistency with the MetroScan data. 3. Single Family Rates: The data on all new single family detached residential units in MetroScan were compared electronically with the District's student record data, and the number of students at each grade level living in those units was determined. The records of 3,898 single family detached units were compared with data on 17,944 students registered in the District, and the following matches were found: K-5 = 1,079, 6-8 =451, and 9-12 =469. This resulted in the following SGR's: K-5 6-8 9-12 K-12 Single Family .277 .116 .120 .513 4. Overall Multi-Family Rates: The methodology described above for calculating the single family SGR's was also used for calculating the overall multi-family SGR's. The records of 1,688 multi-family units were compared with data on 17,944 students registered in the District, and the following matches were found: K-5 = 230, 6-8 =97, and 9-12 = 102. This resulted in the following SGR's: K-5 6-8 9-12 K-12 Multi-Family Overall .136 .058 .060 .254 5. Multi-Family 0-1 and 2+ Bedroom Rates: MetroScan data could not be used to differentiate between 0-1 bedroom units and 2+ bedroom units. This was because -
