Preschool teachers support dual language learners by making the classroom work in two languages at once: predictable routines narrated in short, repeated phrases, directions carried by visuals and gestures as much as by words, labels and songs in each child's home language, and families kept in the loop in the language they speak.
The scale of the work is easy to see in Head Start's own data — 35% of children enrolled were dual language learners in 2023-24.
Who are dual language learners?
A dual language learner is a young child learning English while continuing to build the language of their home.
That is the term the Office of Head Start uses in its program data; program names and job ads reach for overlapping labels — a dual language preschool, a bilingual classroom, ESL support — for work that overlaps just as much.
The numbers are worth reading at their own scope.
In the 2023-24 program year, 35% of children enrolled in Head Start were dual language learners, and 63% of those children were in families that primarily spoke Spanish at home.
Those are Head Start figures from the Office of Head Start's program facts — a benchmark for Head Start classrooms, not a private-center average.
For a teacher, "dual language learner" is less a category of child than a slice of the job.
Each child arrives with a different mix: one hears only Spanish at home and meets English in your room; another moves between both languages all day; a third switches to English the moment they arrive.
The support work looks different for each, which is why it is a skill and not a checklist.
This page covers that skill — the classroom strategies, the home-language work and the credentials — as one layer of the preschool teacher career guide, which covers the role as a whole: duties, settings, requirements and pay.
Classroom strategies that work
None of this requires a curriculum purchase.
The moves below are ordinary teaching pointed at language: they slow your words down, attach meaning to sound, and give children more turns to talk.
- Narrate the day in short, repeated phrases. "Now we wash hands." "First cleanup, then story." The same sentence at the same moment each day is a language lesson wearing a routine.
- Show while you say. Gesture, point, hold up the object. A direction carried by a picture works before the English arrives.
- Label the room in every language enrolled. Ask families to write the words with you so spellings and accents come out right — the labels tell children their language belongs on the wall.
- Sing and count in both languages. Songs and finger plays repeat themselves, which is exactly what language learners need.
- Recast instead of correcting. A child says "manzana"; you answer, "Yes — a red apple." The correction sits inside the expansion, and nobody is embarrassed.
- Take answers in either language. Comprehension runs ahead of speech, so a child who points, fetches or acts out the story is telling you the English landed.
- Work in small groups. Fewer children per adult means more back-and-forth turns for the children who need them most.
- Pre-teach a story's key words. Two or three vocabulary words in both languages before circle time turn a read-aloud from noise into a lesson.
Watch what children do rather than what they say in English.
Following a direction, matching a picture and joining the gesture are all evidence of understanding — and a quiet child may well be listening, not lost.
One caution belongs next to that observation: language difference is not developmental delay.
When a genuine concern about a child's development comes up, route it through your program's screening process instead of a hunch.
Head Start programs, for example, must complete or obtain a developmental screening within 45 calendar days of when a child first attends (30 days for programs operating 90 days or less), using research-based standardized tools (45 CFR 1302.33).
An August 2026 proposal would rescind that section; until a final rule publishes, the current standard stands — confirm the rule with the Office of Head Start.
Supporting the home language
The classroom half is only half.
Your room has a dual language learner for a slice of the week; the home language is where that child already thinks, counts and argues with a sibling.
A classroom that treats the home language as an asset gets a child with both languages to build on — one that only tolerates it gets a child editing themselves before they speak.
So partner with families deliberately:
- Ask families for the words that matter — comfort words, "water," "bathroom," the names for feelings — and use them yourself.
- Invite a song, a lullaby or a story from home into circle time, credited to the family that sent it.
- Send notes home in the family's language, and ask your director what translation support your program has rather than assuming.
- Greet each child in their own language at the door. It is a small habit with a loud message.
- Tell families, plainly, to keep speaking the home language at home. The message worth delivering: the home language at home is part of the plan, and the classroom is building the English half.
For job seekers, this section doubles as interview prep.
Expect a version of this question in a dual language preschool: how would you support a child whose home language you don't speak?
The strong answer is the environment-plus-family answer above — visuals, routines, labels, partnership with the family — not an apology for missing a language.
And name every language you do speak; underselling your languages helps nobody.
Bilingual teachers: demand and pay
The demand case runs on two numbers from the same Office of Head Start program data. 35% of enrolled children were dual language learners in 2023-24.
And among the 112,000 Head Start staff who provided child development services — teachers, assistant teachers, home visitors and family child care providers — 31% were proficient in a language other than English.
Spanish carries a specific weight in those rooms: most Head Start dual language learners — 63% in 2023-24 — were in families that primarily spoke Spanish at home.
When you search, try more than one name for the same skill — bilingual preschool teacher, Spanish-speaking daycare teacher — and read each posting's requirement lines for a named language.
If you speak both English and a second language, that is career information: name the languages on your resume, say how you would use them in the classroom, and read the requirement lines when you browse preschool teacher jobs.
What the skill pays is harder to put a number on.
Our wage research holds no bilingual line for preschool teachers — the BLS data we hold for the occupation (preschool teachers, SOC 25-2011) has no bilingual breakout, and we have no sourced differential for language skills — so no figure appears here.
Treat any bilingual premium as an employer-specific question rather than a published figure: ask about it in the interview the way you would about any other part of the offer.
The bilingual CDA
The Child Development Associate (CDA) credential, issued by the Council for Professional Recognition, has a formal bilingual specialization.
To earn it, the Council requires candidates to work in a bilingual setting that has them speak both languages daily and consistently, and to have a working knowledge of two languages.
For a teacher in a dual language preschool, that describes the job you already do.
Language choice runs through the assessment as well.
The CDA exam is administered in English and Spanish at Pearson VUE test centers, with scheduling through Pearson VUE rather than the Council.
Candidates approved for assessment in a language other than English or Spanish take a computer-based exam in that language by remote proctoring, and still complete both the exam and the verification visit.
That approval comes from the Council before the application goes in — American Sign Language counts.
The credential also carries weight in the rooms the demand numbers come from.
Under current Head Start standards, a preschool assistant teacher must at minimum hold a CDA or a state certificate that meets or exceeds it — or be enrolled in an associate or bachelor's degree program, or in a CDA program to be completed within two years of hire (45 CFR 1302.91(e)(3)).
Early Head Start center-based teachers of infants and toddlers need at minimum a CDA or comparable credential with training focused on infant and toddler development (45 CFR 1302.91(e)(1)).
The proposed August 2026 rewrite would strip out qualification rules beyond the statute, but the statutory preschool-teacher, assistant-teacher and Early Head Start center-based teacher qualifications would remain.
If you are building training hours in Spanish, some providers publish Spanish-language course sections — Penn State Extension's Better Kid Care, for example, offers more than 300 online on-demand courses for child care professionals, with a Spanish-language section among them.
The CDA credential guide covers the credential's settings, costs and steps; this page stays on the bilingual angle.
Career information, not licensing or legal advice. Credential rules come from the Council for Professional Recognition, Head Start standards from the Office of Head Start, and state training rules from your state child care licensing agency — confirm current requirements with the body that issues them.
