Participant milestones
| Measure |
L1 First
All participants will receive both interventions (i.e., test materials in English, test materials in Spanish) in a counterbalanced order. Individuals in this arm receive Spanish materials first, then English test materials. Both L1 and L2 assessments will be completed in the same session lasting approximately 3 hours.
