However, we didn’t see significant changes in SAT scores from 2019 to 2023, but our models are different as we only see students in high school once. This does not mean that attendance does not matter, but rather, that we did not see any change.

And using student fixed effects we show that the relationship between the number of days absent indeed change, and in fact, increased between 2019 and 2023. Into other word, for every additional day absent students in 2023 lose more in their test scores than they would in 2019, in ELA and Math.

In this report, we describe the trends in the number of days absent across different groups, like grade. For example, we show that while all grades have higher average number of days absent high school grades show the largest increase

I will be presenting my dissertation work at the Comparative & International Education Society Conference on Saturday afternoon at the Palmer House Hotel. I am excited to keep moving this work forward, and hope this great opportunity will give me an excuse to prepare a couple papers for publication.

Ready for my next read, following the recommendation by @clconaway.bsky.social

As I work more and more on actionable research, learning how best to write and share my research for a general audience has become quite important.

Honored to attend the Illinois Legislative Caucus Foundation tonight.

My favorite part of the evening? Getting to celebrate brilliant Latino/a college students who received a scholarship for college!
