Consultant presents draft school-enrollment projection showing 426-student increase over 10 years

TischlerBise, a planning and demographic consulting firm, presented a preliminary student-enrollment and school-needs study to the Isle of Wight County School Board on Aug. 7, 2025, at Westside Elementary School. The draft report projects a net increase of about 426 public-school students across the division over the next 10 years and includes student-generation rates and guidance on future school sizes and site acreage.

The presentation focused on three objectives, Michael Gillooly, an analyst on the project, told the board: student enrollment projections, student generation rates by housing type and grade, and school-siting guidance. TischlerBise calculated student-generation rates using subdivision-level student counts provided by the district and county address-point housing data. The firm reported student-generation rates of 0.31 students per single-family housing unit, 0.191 per multifamily unit, and 0.392 per mobile home in the subdivisions analyzed.

The study used American Community Survey (ACS) age-cohort counts and Weldon Cooper Center population growth rates as inputs for cohort-survivorship projections. TischlerBise said those inputs, combined with current enrollment ratios, produced a roughly 426-student increase across the district over 10 years. The consultants noted the analysis covered subdivisions only (not the county's full enrollment) and therefore produces a lower raw student count than the districtwide enrollment figures.

The draft also compares projected enrollment to existing building capacities and applies thresholds to flag schools nearing capacity. Table thresholds shown in the draft used 75, 85 and 90 percent bands; staff told TischlerBise that district policy now uses 80, 85 and 90 percent thresholds, and asked the consultants to re-run calculations using 80 percent for the lower threshold.

TischlerBise recommended planning guidance for new construction: elementary schools in the 600–800 student range on 25–30 acres (75,000–100,000 sq ft); middle schools at 700–1,000 students on 30–45 acres (100,000–140,000 sq ft); and high schools at 1,000–1,500 students on 40–60 acres (150,000–225,000 sq ft). The firm said those are guidelines to be adapted in the district planning process.

Board members asked several technical and scope questions. Chair Marsh and other members asked whether the analysis included the towns of Smithfield and Windsor (the consultants confirmed countywide subdivisions were included) and how pipeline housing projects were handled; the consultants said active and approved pipeline developments were reviewed and their assumed absorption was baked into the Weldon Cooper growth rates used for projections. The consultant also said the firm can run project-specific sensitivity analyses when the district or county requests them.

Board members and staff flagged several follow-up items for revision: use the district's updated capacity thresholds (80/85/90), incorporate known space-sharing (for example, Smithfield High using classrooms assigned to the middle school), and ensure programmatic uses (special-education classrooms, administrative uses, IT closets) were accurately reflected in “program capacity” rather than raw student stations. Superintendent designee Christopher Coleman and staff requested time to review the draft and meet with TischlerBise before the report is finalized; the board asked Coleman to coordinate follow-up discussions.

Why it matters: the report provides the district and the county with a data-driven basis to evaluate future school siting, budget requests and coordination with county planning. Board members said they want more time to digest details and to schedule staff-level meetings with TischlerBise before accepting a final report.

"These are preliminary draft findings," Julie Herlands, vice president with TischlerBise, said during the presentation, and the firm asked the board to treat the document as iterative. The board and staff agreed to deliver written questions to staff, who will relay them to the consultants for a revised draft and a schedule of follow-up meetings.

Next steps: TischlerBise will revise calculations using the 80 percent threshold and incorporate staff feedback; Superintendent Coleman will schedule staff-level review sessions with TischlerBise and later bring a refined draft back to the board for additional review and finalization.
