Purpose
To evaluate the efficacy of the Nuestros Niños intervention to promote school readiness for Spanish-speaking dual language learners (DLLs)
Research Questions
- Do Spanish speaking young DLLs in classrooms receiving the Nuestros Niños pre-kindergarten
intervention make greater gains in language, literacy, math and socio-emotional outcomes in their prekindergarten
year compared to their peers in control classrooms?
- Do any specific child, family, teacher, or classroom factors moderate the efficacy of the Nuestros Niños
intervention on child outcomes in the pre-kindergarten year?
- Is there a larger treatment effect in young DLLs in classrooms in the second year of the intervention
compared to young DLLs in classrooms in the first year of the intervention?
- Do Spanish speaking young DLLs who attended classrooms receiving the Nuestros Niños prekindergarten
intervention make greater gains in language, literacy, math and socio-emotional outcomes at the end of
kindergarten compared to their peers who attended control classrooms?
- Do any specific child, family, teacher or program factors moderate the efficacy of the Nuestros Niños prekindergarten intervention on child outcomes at the end of kindergarten?

Instructional Framework Principles of Nuestros Niños Intervention
- Teaching should build on children’s prior knowledge to provide context and meaning to the learning experience.
- The central role of culture in children’s development should be taken into consideration when designing and implementing practices to support young DLLs’ development and learning.
- Bilingualism should be seen as an asset that have the potential to positively impact children’s development and become a source of family strength.
- A positive socio-emotional classroom climate promotes learning.
- Teachers are mediators in the learning process.
- Teaching should build on children’s strengths to reach their full potential.
