Bilingual Daycare: Is It the Right Choice for Your Child?

30th December 2017

In a bilingual preschool, instructors conduct activities in a second language either mixed with the first language or as complete immersion throughout the whole school day. The goal is to expose young learners to a new language they can become proficient in and use later in life.


What Makes a Daycare ‘Bilingual’?

There are different types of bilingual programs depending on the amount of time devoted to the second language in the classroom:

  • Complete or 100% immersion means the program is held 100% in the second language
  • Partial immersion programs are conducted in the foreign language about 50% of the time
  • Two-way immersion, also called bilingual immersion, combines language minority and language majority students in the same classroom. Instruction is in both languages and idea is to get both types of speakers proficient in both languages.

Instructors of bilingual preschools may incorporate the second language using various methods. This will depend on the program and the teacher’s preferences. In some cases, the instructors may adjust how much of the second language they use when speaking to each individual child depending on his or her language level.

They may use the second language the majority of the time and translate into the first language as they go. Early childhood educators may also reserve certain activities, songs, or times of the day exclusively for the second language.

Why choose a bilingual or immersion preschool?

Preschool is a great time for language learning as it coincides with children’s natural ‘critical period’ for language development.

The critical period hypothesis says the nervous system is primed to absorb and discriminate between phonemes – or different language sounds – from birth until about age 5.

You’re born with the potential to discriminate between an infinite number of sounds. For monolingual babies, this ability starts to weaken as their brains become wired especially for the sounds of their mother tongue as they get older. If you’ve heard the saying, “the younger the better” in terms of language learning, this is why.

Language programs for elementary-age children and above often lack the immersion aspect of many bilingual preschools. Instead, these older children may only be exposed to the second language for one or two class periods a week. In these classes, they may review vocabulary or practice literacy skills without necessarily being immersed in the language.

However, research shows social interaction and context are key to learning languages, making preschool an ideal environment for language learning.

Bilingual vs immersion preschool

‘Bilingual’ education is an umbrella term that refers to any program that includes a second language component.

For older children at the elementary and higher grade levels, this often means there is a subject or class, perhaps a few times a week specifically meant to teach children the second language, e.g. ‘Spanish class’. Children attend other classes like Math and Science in their native tongue.

‘Immersion’ programs, on the other hand, specifically immerse students in the second language by teaching school subjects in the second language. For example, Math or Science may be taught in Spanish in addition to English on alternating days of the week.

However, at the preschool level and below, the terms ‘bilingual’ and ‘immersion’ are often used interchangeably as there is rarely formal instructional time but rather a daily flow of play and activities.

Benefits of bilingual preschool

Many parents are interested in exposing their child to a second language at a young age for the cognitive benefits as well as future professional opportunities and exposure to other cultures and ways of thinking.

Bilingual or language immersion preschool benefits children in the following ways:

Cognitive benefits of bilingual preschool

Future professional opportunities

Bilingualism can open doors for your child later on down the road. They may have access to professional opportunities they would have otherwise not had access to because they can speak a second language.

Cultural tolerance and appreciation

Being bilingual can help your child maintain ties to their cultural heritage or grow an appreciation for other cultures and other parts of the world from a young age. This can lead to a greater tolerance, sensitivity, and understanding of other cultures.

All of this said, there is definitely nothing wrong with raising your child in a monolingual environment! There are plenty of successful, intelligent, well-adjusted adults out there who were only exposed to one language during childhood

The pros and cons of bilingual preschool


Your child will be exposed to a new language during the “critical period” for language learning:

  • Children are more likely to acquire a second language if they start early
  • The critical period for language learning spans from birth to about 5 years old. According to researcher Patricia Kuhl, during this time, the human brain is especially primed to learn to distinguish between different sounds. While babies can discriminate all sounds from all languages, adults are culture-bound listeners who struggle to discriminate the sounds from languages they’re unfamiliar with. This means young learners learn native pronunciation easily.

They’ll be ‘exercising their brain’ more than their monolingual counterparts, and this shows in terms of cognitive gains (see above cognitive benefits)

They’ll have a rich understanding and appreciation of another culture

Having a second language under their belts will open up doors in the future from a professional standpoint


Full immersion may make it difficult for students to grasp abstract ideas

If you don’t speak the second language, you may have trouble helping with homework as they get older

They’ll need to stick with it – successful second language proficiency and the resulting benefits come with not just early exposure but continued lifetime practice

Preparing Your Child for Bilingual Daycare

If you’re ready to start your search for a bilingual preschool for your child, you can start by evaluating your options the same way you would for any other preschool. Check out our quality indicator checklist for choosing the best preschool.

If you haven’t already, you’ll need to consider what language you want your child to learn as their second language.

Speaking a second language will open up doors for your child in terms of work and life experiences as they grow. It can be an enriching and exciting new venture for you and your family. But be prepared to make a long-term commitment. Your child will need to stay the path and continue to practice to become fluent.
