The abstract reports a language-group moderation: "EL status led to under-identification for Spanish speakers and proportionate representation for Mandarin/Cantonese speakers and speakers of all other languages." No group-specific effect sizes or test statistics are printed in the available text.

"We also find that EL status led to under-identification for Spanish speakers and proportionate representation for Mandarin/Cantonese speakers and speakers of all other languages."

Discussion¶

Learner Variables¶

English-Learner Status — predictor: learners who differ on it differ in outcomes

EL status had either a null effect or led to slight under-identification in SPED placement — a broader claim this one bears on
Under-identification of SPED placement occurred two years after EL classification — related
Regression discontinuity estimates of EL status effects on SPED placement consistently differ substantively from regression analysis results — related
The kindergarten EL population became linguistically more diverse from 2006 to 2018, with Spanish speakers declining from 83.8% to 77.3% and Mandarin and Arabic speakers more than doubling — related
