Wow they look related to mine

Banking this for the market next year

11/ we look at longer-run outcomes and find little movement except on compulsory ACT scores, which have a (-) effect for our low ability group. Our placebo analysis shows no differences in ACT b/w the groups, suggesting the policy caused deficits in the low group’s performance

10/ Across high school, these differences compound and begin to widen, but the differences between ability groups persists - ie, low ability students never experience positive GPA gains in response to this policy

8/ when we look at these outcomes for “high” and “low” ability students, we see gains for high ability students only and reductions in engagement for low ability students only. We also conduct a simple simulation that suggests low ability students SHOULD be mechanically

7/ we estimate LATEs under a fuzzy RDD with an “honest” RD framework to account for the fact that our running variable is discrete. Overall, we find substantial gains in GPA but potentially larger negative effects on engagement (absences)

6/ rather than compare the 2 cohorts directly, we instrument for HS entry using a separate kindergarten entry rule used by the state. This addresses issues of non-compliance at the 9th grade entry level, as evident by the figure. We then use a fuzzy RD to estimate effects

5/ we want to understand the effect of the policy, & we want to exploit the timing of it on the first cohort of high schoolers facing it; however, the transition from 8th to 9th grade is the second large point of retention for students in K-12, so there’s selection on entry year

3/ the immediate response to the policy is stark, even descriptively. The top panel shows 9th grade course averages in math during the last year of the 7-point scale, and the bottom panel shows the same during the first year of the “lenient” scale

2/ this is the policy in question. Effectively the state moved from a 7-point grading scale to a 10-point scale for all classes. You can see that earning an A became 3 points “easier” but passing a class became 10 points easier.

1/ we first develop a theoretical model to explain how students may respond to a policy that lowers grade standards. We show that this has the capacity to WIDEN or MITIGATE achievement gaps, which depends on the distribution of student ability & the magnitude of the leniency

🚨 New WP 🚨

Joint with Brooks Bowden & Viviana Rodriguez, we analyze the impacts of a policy that explicitly lowered grading standards in high school for all students.
