It is difficult to measure the disruption to a school of students moving both in and out of the attendance area. Net changes in the school enrollments do not capture the impact of moving students in both directions.
For example, the current enrollment of Stephens Elementary School is 444 students. Option B moves 214 students to new schools. At this point only 230 ( 51%) of the current students remain at Stephens. Then Option B adds 100 new students from other schools and the enrollment rises to 330. The net change looks small�90 additional students. However, 314 students have changed schools to make this adjustment. My approach gives Stephens a disruption rate of about 71%.
My chart compares the total number of students moved in and out of ten elementary schools on the west side to the current enrollments of those schools. I use the resulting percentage as a rough measure of disruption to the school. This approach demonstrates that the net change in students may be small, but the number of students changing schools is very large in proportion to the current size of the school in Option B. It is only a rough measure. However, the chart directs attention away from what appear to be minimal net enrollment changes to the impacts that families and schools will experience when coping with moves of students in and out of the same schools.

Option B also has an important impact on one east side school. It moves 120 students from Midvale-Lincoln School to Glendale Elementary School. Glendale School enrollment would increase from 267 to 387, a 45% increase in students in one year.
