Data and Research

Data and analysis provided to the school board and in the community meetings will be posted in this section. Please check back often as the various analytical projects are continually being refined as issues are discussed.

• Data
  • Elementary Reference Area Analysis: Shows the Seattle Public School resident population for each reference area. Data includes the October 2004 enrollment for the elementary schools, the October 2004 SPS resident population (not the total underlying school age population), and the projected 2014 SPS resident population. At a very general level, if students were assigned to their reference area school, this data shows how many students and what characteristics they would have. We recently added a new section of columns that calculate the percentage change between the schools current enrollment and the resident students for the school's neighborhood. For middle and high school neighborhoods, the reference areas that make up each neighborhood are listed on the sheet.
  • Middle School Regional Analysis: Same as the elementary analysis except for middle school regions. The regions are graphical displayed in the option #1 map listed below and the reference areas associated with each middle school region are listed in the this table.
  • High School Analysis: Same as the middle school analysis with high school regions shown on the option #1 map and on the this table.
  • Building Utilization Analysis: See the explanation in the document.
  • Market Share: SPS capture of school age children in Seattle for the 2000 Census and school year.
  • Planning Capacity Analysis: Refer to the presentation on December 13th for a detailed explanation of how this was developed. Using the assumptions stated in the presentation, this table shows by the current elementary clusters what the building capacity, projected resident SPS demand, and the number of buildings required to serve the students at various rates of excess capacity. It uses class sizes of:
    • K-3: 23
    • 4-5: 25
    • 6-8: 28
    • 9-12: 30
  • SEA Capacity Analysis: Refer to the presentation on December 13th for a detailed explanation of how this was developed. Using the assumptions stated in the presentation, this table shows by the current elementary clusters what the building capacity, projected resident SPS demand, and the number of buildings required to serve the students at various rates of excess capacity. It uses class sizes (as generall dictated by the SEA agreement) of:
    • K-3: 26
    • 4-5: 28
    • 6-8: 30
    • 9-12: 30
  • SPS Demographic Outlook: Historical enrollment information as well as a look at long range projections to 2014. This is in a Powerpoint slideshow format.
  • Long Range Projections: Table of enrollment by grade; historical to 2014.
  • Birth-to-Kindergarten: Historical and projected data on the number of births, kindergarten enrollment (five years after births), and the calculated birth-to-kindergarten ratios (B-to-K). B-to-K ratios are used to project future kindergarten enrollment based on actual reported births. Data are taken from Washington State Department of Health.
  • Historical Racial/Ethnic Data: Table with historical data by reference area showing the resident SPS population by ethnicity.
  • Market Share: Table showing the total school age population by reference area (from the 2000 Census and forecast of 2004 and 2009), SPS resident population, and the calcuated market share.
  • Attachments for the March 2, 2005 Board worksession: Three attachments were handed out at the meeting that give various data on enrollment and choices patterns for October 2004. Please read the summary and explanation document for details on each attachment.
    • Summary and Explanation
    • Attachment #1: Elementary, Middle, and High.
    • Attachment #2: Reference area enrollment by cluster.
    • Attachment #3: Reference area choices by cluster. This is for on-time choices only for the 2004-2005 school year.
• Maps
  These maps are for illustration purposes only and should be used to understand the general concepts under discussion. They do not represent actual proposals for specific assignment plan designs. Please read the December 13, 2004 presentation for details on assignment plan concepts. Within each map there is a short explanation of what the map is attempting to represent.

• • Attendance Boundaries Option #1: Students are assigned to a specific elementary, middle, or high school based on their resident address. The only "choice" options are to designated alternative schools listed in blue.
  • Attendance Boundaries Option #2: Students are assigned to a specific elementary, middle, or high school based on their resident address. Choice is offered to designated alternative schools listed in blue and to one or more other elementary, middle, or high school.
  • Attendance Boundaries Option #1 and #2: This map shows a basic analysis of matching attendance boundary Seattle Public School population to "designated" school capacities.
  • Analysis of Current Assignments to Attendance Boundaries proposed in Option #1: See map for description.
  • Density Maps for High School and 'Some' Middle Schools: Maps show the October 2004 enrollment for each listed school by where students live.
    • High: Ballard, Cleveland, Franklin, Garfield, Roosevelt, Sealth, West Seattle, Ingraham, Rainier Beach, Nathan Hale, Center School, and Nova.
    • Middle: Hamilton, McClure, Whitman, and Aki Kurose.

• Presentations
  • Board Work Session on March 2, 2005: Focus was on the feedback from the student assignment community meetings in February and financial models for various transportation plans.
    
• Other Handouts
  • Criteria Options Considered by Staff: Discussion of various criteria and the reasons why they were chosen or dropped off the list for recommendation.
  • Staff Recommended Potential Criteria: List of staff recommended criteria for school closure/consolidation developed from stakeholder, community, and brainstorming sessions.
  • Criteria Metrics: List and brief explanation of staff recommended school closure/consolidation metrics.
  • Timeline: Timeline
  • Revised Criteria : This set of criteria has been revised after the school board work session on March 7, 2005. Please use this as the reference document.
