Obligatory warning: This blog post is written for the eduData wonk audience. We examine in-depth the relationship between demographic factors and STAR scores. The post is super heavy on statistics and data science.

This past December, OSSE released the new common DC School Report Card with STAR scores and ratings for every school and subgroup within the school. Then, in February, parents finalized their school preferences for the SY2019-20 school year. We analyzed the newly released MySchoolDC waitlist data for next year, comparing it to historical data as well as other school factors included on the new report card, to find out whether the new rating system impacted school choice on a broad level.
