Monitor student progress. When a school closes, students from the closed school must attend other schools. The change can impact the academic progress of some students. Ask teachers for quarterly grade reports to assess impact.
Review attendance logs in the schools where the students transferred from the closed schools. Attendance logs will reveal class sizes, which will be bigger in some cases.
Assess student transfer rates out of the district after a pre-determined time frame, such as five years, to gauge district-wide reaction to the school closure. Families may transfer students when they are unhappy with a school closure or when they feel the new class sizes are too big for proper learning.
Review high school graduation rates over a period of years paired with student grade point averages at graduation to help determine the academic effect of a school closure.
