4) We also follow one cohort’s journey from K all the way to grade-8. We observe only 48.5% of students who started as English Learners in kindergarten had been reclassified by the end of grade-5 (‼️)and 73.1% were reclassified by the end of grade-8.

3) In the most recent cohort who we can observe finish grade-5, though 72% of K-cohort EL students were designated as English proficient by the end of 5th grade and thus were eligible for reclassification based on that criterion, barely 50% were actually reclassified.

2) More recent cohorts reached English proficiency in earlier grades than previous cohorts had. But, we see almost no change in the overall share who were proficient in English by the end of grade-5. (Note these cohorts began school before some of these reforms were complete).

1) English Learner academic achievement by 3rd grade has improved over time, shrinking the achievement gaps between K-cohort ELs and other students in English language arts (ELA) and math. See figure below.

Thank you!

Thanks for making this list! I’d love to be included, if there’s room.

I’d like to be added to this list please!

To read more, see @matthewakraft.bsky.social's excellent thread on X or Kevin Mahnken's great coverage in @the74.bsky.social this morning. Or, read the article yourself here journals.sagepub.com/doi/10.3102/... or open-access here edworkingpapers.com/ai22-653.

My big takeaway: Because time affects achievement, we ought to be really careful about interrupting it (e.g., with intercom announcements) or re-structuring it (e.g., four-day school weeks). We also ought to focus on helping kids capture it (e.g., reducing absenteeism).

When we consider inputs into schooling, we often think about teachers and funding (which undoubtedly matter a lot!) But, IMHO we don't spend enough time thinking about how long kids are in school & the consequences of that choice. Our research shows that time affects achievement.

When we compare targeted schools to similar CA elementary schools, targeted schools did 0.14 SD better on ELA tests after 2 years. This wasn’t just a mean difference either. It holds at every part of the distribution. Oh and it improved math scores too!

So what happened? While most schools nationwide suffered big dips in academic achievement post-pandemic with even bigger losses for already low-performing schools, these targeted schools didn’t.
