Dual Language Learner
A dual language learner (DLL) is a child who is exposed to and acquiring two or more languages during early childhood, typically before age 5. This includes children who hear different languages at home and at childcare, or who live in multilingual households where parents speak different languages to one another.
How Development Differs for Dual Language Learners
DLL children don't simply learn two languages at the rate of one monolingual child. Research shows that their combined vocabulary across both languages develops typically, but when measured in a single language, they may initially appear to have smaller vocabularies. A 3-year-old DLL might have 500 words in English and 400 in Spanish (900 combined) while a monolingual peer has 900 in English alone. By age 5, most DLL children reach comparable proficiency benchmarks in both languages when assessed appropriately.
The critical factor is that childcare staff and parents continue supporting both languages consistently. Children lose language exposure without regular practice, particularly the home language when English dominates at school.
Licensing and Accreditation Implications
State licensing regulations don't typically mandate bilingual staff, but NAEYC accreditation standards require centers to support children's cultural competence and home language development. This means programs should at minimum label classroom materials in children's home languages and communicate with families in their preferred language.
Staff-to-child ratios remain the same regardless of DLL enrollment. For infants, the federal Child Care Development Fund (CCDF) subsidy guidelines do not adjust reimbursement rates based on language needs. However, some states' quality improvement initiatives specifically fund bilingual staff or interpreter services for centers serving high percentages of DLL children.
Practical Classroom Strategies
- Use picture labels and books in both languages, even if staff don't speak them fluently
- Invite family members to contribute songs, recipes, or stories in home languages during circle time
- Assess language development in both languages separately, not just English, to avoid misidentifying language difference as language disorder
- Maintain consistent language zones: one teacher uses English, another uses Spanish, for example, rather than code-switching constantly
- Connect families with community resources for maintaining home language at school age
Common Questions
- Will learning two languages confuse my child or delay speech? No. Bilingualism does not cause confusion or delay. Children naturally acquire multiple languages when exposed consistently. A child with a speech disorder will show delays in both languages; a child learning two languages will have typical development across both.
- Should I speak only English at home so my child does the same at childcare? Research strongly recommends maintaining your home language. Children benefit cognitively from bilingualism, and if you stop speaking your language, your child loses that valuable resource. Quality childcare serves as English exposure; home provides irreplaceable first-language development.
- How do I know if a program supports DLL children well? Ask whether staff have training in multilingual development, whether the program assesses children in both languages, and whether family communication happens in your language. Programs serving 20% or more DLL children should have intentional bilingual practices beyond basic translations.
