OSPI releases new way to measure student success

The state Office of the Superintendent of Public Instruction released a new measure of student performance Dec. 9, known as Student Growth Percentiles.
The percentiles are designed to measure the amount a student learns during one year and to show how students grow over time compared to their academic peers, students who earned similar scores on a prior test.
“We shouldn’t look at the data in just one way,” state Superintendent Randy Dorn said in a news release. “We need multiple measures. If a school is showing high growth from year to year, we should celebrate that. They’re doing exactly what they need to do to help kids be successful.”
pThe OSPI will report student subgroup, school and district-level median student growth percentiles publicly at http://bit.ly/datareports.
School districts have the choice whether they’ll distribute student growth reports to parents and students.
The state Board of Education plans to use school median SGPs as one of its measures in the revised Achievement Index, a snapshot of a school’s performance based on statewide assessments. It compares how schools perform in reading, writing, math, science and graduation rates.
Teacher evaluations are a potential use for SGPs in the future. With new assessments coming to schools in the 2014-15 year, the OSPI is recommending districts wait until 2016-17 before using SGPs in evaluations.
