2014-15 Performance Index

Written by ONE Olentangy on .

The Ohio Department of Education (ODE) has released Performance Index data for the 2014-15 school year. Olentangy is ranked first in Central Ohio and is ranked eleventh in the state for Performance Index overall from twenty-sixth last year.

ODE officials have stated that they are required to include all student test scores in the Performance Index score, including students who opted out of the test. This means that those students who opted out are counted as zeroes. Due to concerns about reflecting accurate achievement, ODE has released a second Performance Index this year that is modified to include only those students who actually took the tests.
In addition, Olentangy is ranked first in the state for highest value-added  gain index for all students, gifted students and students with disabilities.
Below is a comparative chart among central Ohio school districts. The second column is the "Performance Index - Overall", which includes zeroes for those students who opted out or were untested. The third column is the "Performance Index - Modified", which includes only those students who were tested. Data is sorted on the second column in descending order.
