These subdivided groups are all similar, but are called 1a, 1b, etc. Please note that numbers in this report may differ slightly from numbers reported in school district report cards, earlier news reports, or the DESE web site. This is because DESE staff regularly updates the figures in their databases. PEER used the most accurate and recent data available at the time the report was created. Some studies show that high mobility affects student achievement.
Mobility is a calculated index number.
The higher the mobility index number, the higher the student mobility. On average, the percentage of students in a district who actually attended school. Some studies show that low attendance is related to achievement and dropout rates. The rate at which local property owners have voted to tax themselves to support schools in their district.
