What is dual language immersion? A parent's guide for Western NC.

10 min readFor parents new to immersionUpdated 2026

Draft in review. This guide comes from the working draft already in Kelsey's review round - final wording may shift.

If you've started searching for "Spanish immersion school" or "bilingual kindergarten" in Western North Carolina, you've probably noticed the same thing we did before opening Sol & Son: there isn't much out there.

Macon County has no public dual-language program. The closest comparable schools are two hours away in Asheville, and most of what comes up online is either "Spanish class once a week" or full-time classroom programs in cities much larger than Franklin. Parents who want a true bilingual education for their child are usually told it isn't an option here.

It is. And once you understand how dual language immersion actually works, the why becomes obvious.

This is the parent's guide we wished existed when we were researching schools for our own kids. It walks through what dual language immersion is, what it isn't, what the school day looks like, what the research says about kids learning two languages from age four onward, and what we've built at Sol & Son to make it work for families across Macon, Swain, Jackson, and Clay counties.

What dual language immersion actually means

Most "Spanish programs" in U.S. elementary schools fall into one of three categories:

Spanish class. Twenty or thirty minutes a day, usually a few times a week, taught the same way schools teach French or Latin. Students learn vocabulary and grammar but rarely become conversational. This is what most parents picture when they hear "Spanish at school."

One-way immersion. A class made up of native English speakers who are taught core subjects (math, science, social studies) in Spanish for part or most of the day. The goal is for English-speaking children to become bilingual. Kids learn Spanish through learning their other subjects, not as a separate class.

Two-way (dual language) immersion. A class made up of both native English speakers and native Spanish speakers, learning together in both languages. Each group becomes bilingual and biliterate, and each group helps the other along the way. This is what we do.

The shorthand "dual language immersion" gets used pretty loosely online, so it's worth being specific: when we say it, we mean two-way, with native speakers of both languages in the same room, learning math in Spanish and reading in English (or vice versa) and recess in whatever the kids are using on the playground that day.

How the immersion model works at each grade

Sol & Son uses a graduated immersion model. The youngest grades carry the heaviest Spanish exposure to build a strong foundation, and the English share grows gradually as kids develop literacy in both languages:

  • Pre-K Enrichment: 90% Spanish / 10% English
  • Kindergarten: 90% Spanish / 10% English
  • 1st Grade: 90% Spanish / 10% English
  • 2nd Grade: 80% Spanish / 20% English
  • 3rd Grade (added in 2027-28 as the school grows): 70% Spanish / 30% English

The reasoning is straightforward. The early years are when a child's brain is most ready to absorb a second language naturally, so we protect that Spanish-heavy foundation all the way through 1st grade. As kids gain confidence and start reading and writing in both languages, the English share grows — by 3rd grade, students are fluently biliterate, and the daily balance reflects that. The total bilingual outcome is the same; what changes is the rhythm of how kids get there.

Here's roughly what a school day looks like in Kindergarten (the heaviest Spanish year):

  • Morning meeting in Spanish. Calendar, weather, the day's plan, a song or two.
  • Math in Spanish. Manipulatives on the table, conversation in Spanish, written work mostly in Spanish with key vocabulary in both languages.
  • Project-based learning blocks — our core curriculum framework — in Spanish. A unit might be "how does our community get its food?" with field studies, art, writing, and presentations all woven through.
  • Reading and language arts intentionally split: a Spanish block and a smaller English block, both happening on most days. The English block protects English literacy from the start, even at the heaviest Spanish ratios.
  • Specials (art, music, P.E., character formation) — most in Spanish, character formation often in English.
  • Recess and lunch — kids do what kids do. Both languages, lots of laughter, occasionally a translator emerges from a six-year-old.

By 2nd grade, the English block widens — kids are reading more independently in both languages, and content writing moves into both languages too. The structure of the day stays familiar; what changes is how much of it is happening in English alongside the Spanish.

Kids are not lost in Spanish. They have a teacher, classmates, and a structure that makes meaning clear before they understand every word.

This is how every bilingual person on Earth learned a second language as a child — by being immersed in it, with caring adults pointing things out.

Two-way immersion: why having both groups in one classroom matters

This is the part most parents miss when they first hear about dual language. It would be possible to teach English-speaking kids in Spanish without any native Spanish speakers in the class. Plenty of "immersion" programs do exactly that. But it isn't the same thing.

When a class has roughly half native English speakers and half native Spanish speakers, three things happen that don't happen in a one-way classroom:

Kids become each other's teachers. A native English speaker working through a Spanish math problem has a real classmate to ask, not just a teacher. A native Spanish speaker stumped by an English worksheet has a peer to lean on. The cross-help isn't engineered — it just happens, and it's one of the strongest predictors of long-term bilingual outcomes.

Both languages have authentic status. When English is the only "real" language and Spanish is the school's "instruction language," kids feel that hierarchy and often quietly drop their Spanish as they age. When both languages are someone's first language in the room, neither one is the secondary one.

Cultural learning is honest. A bilingual classroom isn't a culturally homogenous classroom. Kids encounter different traditions, food, holidays, and family structures because their classmates live them — not because a curriculum tells them to. This shapes how children see the world more than any single lesson could.

What the research says (the short version)

You'll find a lot of long-form research papers if you go looking. The honest summary, from decades of peer-reviewed work:

  • Bilingual children's reading and math scores match or beat their monolingual peers by 4th–5th grade, across socioeconomic backgrounds. The often-feared early dip in English reading scores in K and 1st is real, modest, and closes by mid-elementary.
  • Bilingual brains develop measurable advantages in executive function — the capacity to focus, switch tasks, and work through ambiguity. The effect is visible in kids and lasts into adulthood.
  • Speaking two languages from early childhood does not delay speech. Kids in dual-language environments may mix their two languages early on (called "code-switching"), which is a sign they're processing both, not a sign of confusion.
  • Bilingual education correlates with stronger long-term cognitive resilience, including delayed onset of cognitive decline in older adults. (We're not selling our four-year-olds on Alzheimer's prevention. But the through-line of bilingualism's lifelong cognitive benefit is striking.)

Two studies parents often ask about, if you want primary sources: Bialystok's 2018 review in NeuroImage on lifelong bilingualism, and Zero to Three's parent-friendly summary of dual language development. Both are easy reads.

Common parent worries, answered

These are the questions we hear most often, in roughly the order they come up.

No. K and Pre-K students arrive in this exact situation all the time. The 90/10 immersion intensity in the early grades and the two-way classroom are designed to surround a non-Spanish-speaking child with meaning — gestures, visuals, peers, predictable routines, caring teachers — long before she understands every word. The first few weeks are an adjustment. By month two, kids are usually using Spanish phrases at home without realizing it.

Yes, and it matters less than you'd think. The most important things parents do — read aloud (in English is fine), talk about the day, ask about what they're learning, show up for events — work in any language. We send home parent-friendly notes about what we're working on, and there's a built-in network of Spanish-speaking families happy to help with the occasional homework question. We've never had a monolingual English family struggle with this.

A small, temporary dip in English reading scores in K through early 1st grade is well-documented and expected. By 2nd–3rd grade, dual-language students consistently match or surpass their monolingual peers. We protect English literacy with daily focused English reading and writing time from day one — even at the heaviest 90/10 Spanish ratios in K and 1st — and the English block widens as kids progress.

Children who have spent their early years in dual-language immersion don't lose what they learned. They may slow their Spanish acquisition, but the foundation — fluency, comfort, the ability to think in two languages — stays. Many continue to develop their Spanish through home use, summer programs, or middle/high school courses.

It really isn't. A Spanish class is a class about Spanish. Dual language immersion is the school day, in Spanish, with Spanish-speaking peers, with academic content equivalent to any high-quality elementary curriculum, plus the bilingual outcome.

Why this matters in Western North Carolina specifically

There's a practical reason families across Macon, Swain, Jackson, and Clay counties drive to Franklin for school: there isn't another option for this kind of education in the region.

Macon County's public school system has many strengths but no Spanish immersion track. Buncombe County, two hours east, has the closest public dual-language program. Asheville's private dual-language schools are also two hours away and full. Between Asheville and the Georgia line, the only Spanish–English dual-language elementary classroom is ours.

That's why Sol & Son exists, and why the families who've found us have come from places it would be hard to predict — from down the road in Otto, from Highlands and Cashiers, from Bryson City, from Sylva, and from across the Georgia line in Clayton.

Dual language education is something families travel for, because what it gives a child compounds over a lifetime.

The other reason it matters here: Western NC is more bilingual than people often realize. Macon County's Hispanic population is meaningful and growing, and many of those families want their children to maintain Spanish at the same level as English while becoming fully fluent in their second language. Two-way immersion serves both communities at once. We exist for the family from Franklin who wants their child to grow up bilingual, and the family from Andrews who speaks Spanish at home and wants their child's heritage language formally protected and developed in school.

How Sol & Son lives it day-to-day

Knowing the model and seeing it in practice are two different things. A few specifics about how we run:

Native Spanish-speaking teachers from Mexico, Puerto Rico, Venezuela, and beyond. Our teachers aren't English speakers who learned Spanish in college — they grew up in Spanish-speaking countries and bring the cultural fluency that goes with it. (They also bring great cooking, but that's a different post.)

A four-day in-person school week, plus a Friday virtual day for K and up. Mon–Thu, families show up at 1150 E Main Street for a full school day. Friday's virtual day runs from 9 to 10 AM, with structured asynchronous follow-up, and gives both families and teachers a sustainable rhythm. Pre-K Enrichment runs half-day, two or four days a week, on a separate cadence — it's an on-ramp into the dual-language environment for younger children, not a daycare alternative.

Project-based learning rooted in biblical character formation. The school's three pillars — Biblical Character, Authentic Community, and Cultural Diversity, all centered on Christ — show up in the way curriculum is built, not as a separate "morality class." Kids learn what stewardship, kindness, courage, and humility look like inside the everyday rhythm of math, reading, recess, and conflict resolution.

Tuition that's actually accessible. Sol & Son is a confirmed NC Opportunity Scholarship participating school — an approved Direct Payment School — which means the state will cover a meaningful portion of tuition for any North Carolina family, with funds paid directly to the school. For families at the lowest income tier, out-of-pocket can be as low as $48 per month. That isn't a typo, and it's the single biggest piece of news many parents we talk to haven't heard.

See it for yourself

Words on a page only do so much. Dual language immersion is something parents really only "get" when they walk into a classroom and watch kindergartners cheerfully arguing about a math problem in Spanish, or see a group of first graders read a story together in two languages without anyone making a big deal out of it.

If anything in this guide resonated with what you want for your child, the next step is a tour. We do them by appointment, Mon–Thu — call us, email, or book a time on the calendar. There's no pressure and no commitment, just a real look at what we do.

The best way to understand immersion is to watch it happen.
