Hispanic Student Decline and English-Learner Mediation

Why did Hispanic students lose the most ground after 2022, and does English-learner status mediate the effect?

Causal (mediation analysis)

What is this question really asking?

From 2022 to 2024, Hispanic students' math scores dropped 3.4 points nationally and 4.1 points in Texas — more than any other racial or ethnic group. Many Hispanic students are also classified as English learners. The question is: did the decline happen because of something about being Hispanic, or because of something about learning English during disrupted schooling?

Why classification matters. This is a mediation analysis — we are testing whether English-learner status is the pathway (the mediator) through which Hispanic identity connects to the score decline. If you turn off the mediator — by comparing only non-EL Hispanic students to non-EL White students — and the gap shrinks or disappears, language status is the mechanism.

How you would investigate it

  1. Split Hispanic students into two groups. Group A: Hispanic students who are classified as English learners. Group B: Hispanic students who are not. If Group A's scores dropped much more than Group B's, language interruption during remote school is a strong candidate explanation.

  2. Rule out poverty as the real driver. Hispanic students are more likely to qualify for free or reduced-price lunch (a standard proxy for low family income). Compare Hispanic and White students at the same lunch-status level. If the gap shrinks dramatically, income — not ethnicity or language — may be the underlying factor. This is called testing for a confound.

  3. Check if the pattern is the same everywhere. In Texas, over half of students are Hispanic. In Vermont, fewer than 5% are. If Hispanic students declined similarly in both states, the mechanism is not about being concentrated in particular schools or districts.

  4. Run a formal mediation model. A mediation analysis quantifies how much of the Hispanic decline "flows through" the EL pathway. The classic approach (Baron & Kenny, 1986) runs three regressions. Modern alternatives use bootstrapping (Preacher & Hayes, 2004). If EL status explains 70% of the decline, language is the main story. If it explains 10%, broader forces — school funding, segregation, teacher quality — are at work.

Data you would need

What Source Example
Scores by race × English-learner status NAEP Data API (crosstab) Hispanic EL: −5.2 pts; Hispanic non-EL: −1.8 pts
Scores by race × poverty status NAEP Data API (crosstab) Hispanic free-lunch vs. non-free-lunch
School % LEP enrollment NAEP school survey C046501
State EL enrollment trends NCES Texas EL: 18% → 20% of enrollment

NAEP API variables: SDRACE, LEP, SLUNCH3, C046501, C044006

Analytic method: Mediation model with SDRACE as predictor, LEP as mediator, and 2022–2024 score change as outcome. Oaxaca-Blinder decomposition at the state level decomposes the Hispanic decline into within-EL and within-non-EL components.
