Contiguous boundaries: Attempt to maintain contiguous school boundaries without using satellite

attendance areas.

Respect neighborhoods: Avoid dividing easily recognized “neighborhoods” or identified

“developments” or “sub- divisions” unless it is necessary to meet other guidelines. Whenever possible and practical use major highways, railroads, rivers, and streams as natural boundaries.

Proximity to schools: While it is recognized that all students cannot be assigned to their closest

school, consider students proximity to other schools when creating school boundaries.

School Board Priorities

9

School Board Priorities

Modify feeder systems: In order to maximize facility use and establish reasonable numbers of students at each site,

consider the use of 6 middle school feeder systems instead of 5. This would allow smaller, more instructionally suited middle schools and less dependence on mobile classrooms.

Stay within enrollment capacities: Unless it is likely that a school enrollment will be declining, assign students to the four high

schools in a way that their enrollments are under established capacities.

Consider anticipated growth: Enrollment growth patterns should be taken into consideration, where feasible, to ensure

that anticipated growth will not adversely impact one school significantly more than the others.

Enrollment balance: In keeping with the intent of SB612, attempt to balance the percentage of academic and

economic populations at each middle and high school.

IPSAC – Methodology

OPTIMIZATION

30

Operations Research techniques enable users to solve large-scale optimization problems involving many variables and constraints.

The driving variable in the optimization algorithm is total distance traveled by students to school. The solutions generated by these OR techniques are optimal in the following way:

the system-wide student travel distance is minimized while satisfying constraints such as

building capacity


31

Optimization of Attendance Boundaries

OR techniques allow the exploration of holistic scenarios that can provide maximum efficiency for the entire district.

32

The optimization process examines multiple school site/assignment schemes and continually re-calculates the constraint variables for each school in the impacted area...

Ultimately determining the optimal school site/assignment that will:

1. Minimize transportation costs

and 2. Satisfy the constraints

within the impact area.

Optimal scenarios can be then fine-tuned by staff to address transportation and other issues.

35

Located southeast of Raleigh/Durham/Chapel Hill, Johnston County NC has experienced tremendous growth over the last two decades. As an OREd client since 1990, Johnston County Schools have used the data-driven planning tools in IPSAC to locate new school sites and draw attendance zones to accommodate and increasing student population.

In 2010, JCS opened two new high schools – the culmination of years of careful planning and hard work.
