This post provides an update to my January, 2018 post regarding the ISBE growth model under the Every Student Succeeds ACT (ESSA). Based on recent information provided by the Accountability Technical Advisory Committee’s (TAC) recommendations to ISBE, it is likely that ISBE will move away from linear regression toward Student Growth Percentiles (SGPs) as a means to measure student growth under the new school improvement and accountability system. SGPs are the focus of this updated video.

It is important to note that there are details that as of the date of this recording have not been approved by ISBE. Therefore, uncertainties still exist as to how ISBE will ultimately utilize SGPs to measure student growth.

Please check back regularly to this post as it will be updated as new information becomes available.

If you have any questions, or topics you would like me to address in future versions, message me on Twitter @jlgatta.
