A bilingual preschool works best when each class has a stable core team in which a Vietnamese teacher and an English-speaking teacher share responsibility for the same children, with clear and equal roles, protected time to plan together and a timetable that keeps both languages present across the whole day rather than confined to set periods. Structures in which the international teacher visits many classes briefly can deliver English input, but they make it hard to build relationships, observe children closely and integrate the two languages into real experiences.
This article looks at staffing from the leader's side: the main team structures bilingual preschools use, their strengths and weaknesses, how to define roles so that both teachers are genuinely co-responsible, how to design timetables for continuity, and the practical pitfalls that recur. The classroom craft of co-teaching across two languages is covered from the teacher's side elsewhere on this site.
Why staffing is a curriculum decision
In many schools staffing is treated as an operational matter: there are a certain number of teachers, a certain number of classes, and the timetable is a puzzle to be solved. In a bilingual preschool, staffing decisions shape the curriculum more than almost anything written in a planning document. Who is in the room, for how long, in which language and with what responsibilities determines what kind of bilingualism children actually experience.
A curriculum that treats Vietnamese and English as working languages for thinking, rather than English as a subject, needs both languages to be present in play, routines, conversations and projects. That is only possible if an English-speaking adult is part of the daily life of the class, not a visitor who arrives for a fixed session. Equally, a curriculum that keeps Vietnamese as the anchor language needs Vietnamese teachers who are full professional partners, not assistants who manage behaviour while someone else teaches.
Leaders should therefore make staffing decisions with the curriculum in front of them, asking for each option what it will mean for children's language experience, for relationships and for the team's ability to plan together.
Common team structures in bilingual preschools
Several structures are used in practice. Most schools adopt one as a default and adapt it for particular age groups or campuses.
| Structure | How it works | Strengths | Watch out for |
|---|---|---|---|
| Paired co-teachers per class | A Vietnamese teacher and an English-speaking teacher share one class all or most of the day | Both languages present throughout, strong relationships, joint observation | Needs real equality of roles and shared planning time; costs more |
| Lead teacher with language partner | One lead teacher, usually Vietnamese, with an English-speaking teacher present for large parts of the day | Clear accountability, good continuity in the anchor language | English partner can become a side role unless planning is shared |
| Rotating English teacher | An English-speaking teacher visits several classes for fixed sessions | Lower cost, wider reach | English becomes a timetable slot; weak relationships; hard to integrate with projects |
| Alternating days or half-days | Different adults or languages lead on different days or parts of the day | Clear language boundaries for children | Continuity of projects and relationships can suffer; demands close handover |
There is no single right answer, and budgets are real. But leaders should be honest about what each structure can deliver. A rotating English teacher model is not a bilingual curriculum in the sense the Global Nexus framework describes, however well that teacher works.
Defining roles so that both teachers are co-responsible
Role confusion is the most common source of tension in bilingual teams. If job descriptions say one teacher "teaches" while the other "assists", both will behave accordingly, and children will learn quickly whose word counts. If no one is clearly responsible for anything, important tasks fall between the two.
A useful approach is to define shared responsibilities and divided tasks separately. Shared responsibilities belong to both teachers equally: knowing every child, observing and recording development, planning the week, communicating with families, and keeping the room safe and welcoming. Divided tasks are allocated for practical reasons and can be rotated: who leads morning circle on which days, who prepares materials for the project, who writes a particular family update.
Leaders should also be explicit about language roles. In some teams each adult uses mainly one language; in others both adults move between languages in planned ways. Whatever the choice, it should be written down, discussed with the team, and reviewed as children and teachers change. Unspoken assumptions about language use cause more friction than any disagreement that has been aired.
Continuity for babies and toddlers
The younger the children, the more staffing stability matters. Babies and toddlers build secure relationships with a small number of familiar adults, and research on attachment and early development, including the work summarised by the Harvard Center on the Developing Child on responsive relationships, emphasises how much early learning depends on those relationships. A toddler who meets five or six different adults in a week has less chance to form them.
For under-threes, many schools adopt a key person approach, in which each child has one named adult who knows them particularly well, handles most of their care routines and is the main point of contact for the family. In a bilingual setting the key person may be Vietnamese or English-speaking, but either way the child needs a consistent adult present most of the day. Leaders should resist using toddler rooms as places to absorb staff shortages or as the first assignment for new teachers.
For older children, continuity still matters, but children can manage more variety. Even so, keeping the core team of each class stable for the whole school year, and planning handovers carefully when changes are unavoidable, protects children's sense of security and the team's knowledge of them.
Designing a timetable for a bilingual team
A timetable can either support the curriculum or quietly undermine it. Leaders reviewing a draft timetable can check it against a few questions.
- Are both languages present across the whole day, including routines such as meals, arrival and outdoor play, rather than only during planned activities?
- Does each class have long, uninterrupted periods for play and project work, or is the day cut into short segments by specialist visits?
- Do the two teachers who share a class have at least one regular, protected planning time together each week?
- Are staff breaks arranged so that real ratios remain safe and each class keeps at least one familiar adult at all times?
- Is there a clear plan for covering absence that does not routinely pull coordinators or teachers from other age groups?
- Are specialist sessions, such as music or movement, connected to the current project rather than standing alone?
A timetable that passes these checks will rarely look tidy. Bilingual preschools that run well often have fewer specialist slots and more open time than parents or new staff expect.
The support structure around each class team
Class teams do not work in isolation. Behind every pair of co-teachers, a bilingual preschool needs a small support structure: a coordinator who joins planning and observes practice, someone with responsibility for language across the school, cover arrangements that keep familiar adults with children, and access to specialist advice when a child needs more support than the class team can provide.
Support staff matter too. Care assistants, cooks, cleaners, guards and drivers all spend time with children and shape their experience. In a bilingual school they are usually Vietnamese-speaking, and they are part of the Vietnamese language environment children live in. Including them in basic induction about the curriculum, how the school talks with children and what it expects of every adult, helps keep the approach consistent beyond the classroom door.
Leaders should also think about the support teachers themselves need. Co-teaching across languages and professional cultures is demanding. Regular check-ins with each pair, an easy route for raising concerns about the partnership, and willingness to mediate early when relationships become strained prevent small frictions from becoming the reason a good teacher leaves.
Finally, the structure should be visible to families. Parents who know who their child's two teachers are, what each does and who to speak to about what are more likely to trust the arrangement and less likely to see the English-speaking teacher as the only "real" teacher in the room.
Recruitment balance and team composition
Leaders building bilingual teams have to think about the balance of experience across the team, not only about filling individual posts. A team made entirely of new international teachers, however capable, will struggle to understand Vietnamese families, the national programme and local expectations. A team in which all experienced staff are Vietnamese and all English-speaking staff are new can create an unhealthy dynamic in which language and seniority line up.
Healthy teams usually mix experienced and newer staff in both language groups, include at least some teachers who are comfortable in both languages, and have a mix of professional backgrounds. Bilingual Vietnamese teachers are particularly valuable, because they can bridge conversations between colleagues and families and model fluid language use for children.
International teachers need to be recruited with care. Their qualifications and background checks need verifying, and work authorisation is a separate legal process that should be handled by specialists. Leaders should also be clear with candidates about the school's approach, since teachers expecting an English-only immersion model may find a bilingual classroom unfamiliar at first.
Pitfalls that recur, and how to avoid them
The first pitfall is the visiting expert model creeping in by default. When an international teacher leaves, a school under pressure may spread the remaining English-speaking staff across more classes for shorter visits. This feels like a temporary fix and often becomes permanent. Leaders should treat any move towards rotation as a change in the curriculum, not merely in staffing, and discuss it accordingly.
The second pitfall is unequal status. Differences in pay structures, contract terms or titles between groups of staff can turn into differences in professional standing if leaders are not careful. Whatever the contractual differences, classroom roles, voice in planning and access to professional development should be equal.
The third pitfall is neglecting the handover. When teams change mid-year, the incoming teacher needs time with the outgoing one, access to observations and development records, and a gradual introduction to children and families. A Monday morning swap leaves children unsettled and the new teacher starting from nothing. A deliberate handover of even a few days makes a real difference.
The fourth pitfall is measuring the wrong thing. Schools sometimes report the number of English hours per week as their main indicator of bilingual provision, and staff the timetable to maximise it. Hours matter, but what children hear and do during those hours matters more. Forty minutes of an English-speaking teacher absorbed in a project with a small group, talking, listening and extending ideas, is worth more than several hours of whole-class instructions in English. Leaders who track the quality of language interaction, through observation and documentation, make better staffing decisions than those who track hours alone, and they can explain those decisions more convincingly to families who ask how much English their child will get.
Câu hỏi thường gặp
What is the best staffing model for a bilingual preschool?
Many schools find that pairing a Vietnamese and an English-speaking teacher in each class, with equal roles and shared planning, best supports a curriculum in which both languages are used for real experiences throughout the day. Budgets and context may require adaptations.
Why is a rotating English teacher model a problem?
When an English-speaking teacher only visits classes for fixed sessions, English tends to become a timetable subject, relationships with children stay shallow and it becomes hard to connect English to projects and routines, which a bilingual curriculum depends on.
How should roles be divided between Vietnamese and international teachers?
Core responsibilities such as knowing children, observing, planning and communicating with families should be shared equally. Practical tasks can be divided and rotated. Language roles should be agreed explicitly and written down rather than left to assumption.
Why does staff continuity matter so much for babies and toddlers?
Very young children learn through secure relationships with a small number of familiar adults. Frequent changes of staff make it harder for them to feel safe and to engage, so many schools use a key person approach for under-threes.
How much planning time should co-teachers have together?
At least one regular, protected session each week is a sensible minimum, in addition to brief daily check-ins. Without shared planning time, co-teaching tends to slide into one teacher leading and the other assisting.
What should happen when a teacher leaves mid-year?
The incoming teacher should overlap with the outgoing one where possible, have access to observations and development records, and be introduced gradually to children and families. Even a short planned handover is far better than an abrupt swap.
