Compromised Data Integrity in Student Enrollment Projections for HCPSS School Redistricting from Polygon 147

The titled “Compromised Data Integrity in Student Enrollment Projections for HCPSS School Redistricting” was shared by Polygon 147.

Three highlights:

1. In 2017 Feasibility Study and AAC process, OSP ( Office of School Planning) was using outdated 2014 and inaccurate new housing unit data at the polygon level, even they had access to the 2016 data.
2. 45% of all the ES-level enrollment projections fluctuate by more than 10% just between the 2016 Feasibility Study and the 2017 Feasibility Study, while these projections should be very stable in consecutive years.
3. Evidence therein shows that OSP used the wrong inputs data for 45% of all polygons when projecting student enrollment data, and the project errors can be larger than 50% for some polygons.

How can it be? Where is the accountability if these three claims are true?
