How do I interpret the CORE Academic Growth Model results?

The result of the CORE Academic Growth Model can be interpreted as a measure of a school’s contribution to a student’s growth in achievement from one year to the next.

Results are reported on a 0-100 Student Growth Percentile (SGP) scale where higher numbers mean higher growth and lower numbers mean lower growth.

On this scale “50” represents students growing at an average rate compared to students with similar test histories and characteristics from across the CORE Districts. If a school receives a “50”, that means their contribution to students’ growth in achievement is close to the CORE Districts average.

Numbers higher than “50” represent students growing at a rate faster than average. These schools’ contributions to students’ growth in achievement is higher than the CORE Districts average.

Numbers lower than “50” represent student growing at a rate slower than average. These schools’ contributions to students’ growth in achievement is lower than the CORE Districts average. A result less than “50” does not mean that students lost knowledge, it means that they are growing at a rate slower than average for similar students across the CORE Districts.
