Heritage learners are not behind. They are different.

A heritage Spanish learner sitting in a Spanish 2 class is not a slow Spanish 2 student. She has a different acquisition profile, different gaps, and different needs. Treating her like a delayed L2 learner is the most common pedagogical mistake in American world language classrooms.

The acquisition profile, in plain language

A heritage learner acquired her family language at home, usually before school age, and then shifted into English as her dominant academic language. By high school she typically has strong listening comprehension, fluent informal speech, intact cultural intuitions, and gaps in literacy, register, and metalinguistic knowledge (Valdés, 1995; Beaudrie and Fairclough, 2012).

That profile is the inverse of an L2 learner's. The L2 learner has spent four years working from the page outward. She can conjugate tú and usted on a worksheet. She cannot order food in Mexico City without rehearsing. The heritage learner can order food in Mexico City fluently. She has never seen the conjugation chart and might not be able to identify which form she just used.

These two students have nothing in common except the language on the cover of the textbook. Putting them in the same class with the same lesson plan is a logistical default, not a pedagogical decision.

What heritage learners actually need

Maria Carreira's framework (Carreira, 2016) names four priorities for heritage instruction in mixed-class settings.

First, literacy. Most heritage Spanish learners read Spanish at well below their oral proficiency. Reading volume in the target language is the single largest predictor of academic Spanish growth. The implication is unromantic: heritage learners need to read books in Spanish, regularly, at appropriate levels. This is the same prescription Krashen wrote for any learner. It applies more, not less, to heritage students.

Second, register and genre. Heritage speakers usually have one register: the family register. They can speak warmly to grandparents and casually with cousins. Academic Spanish, formal professional Spanish, and the written register of newspapers feel foreign. The work is not correcting their home Spanish. The work is adding registers they have not yet had reason to use.

Third, cultural and historical literacy. Many heritage students have deep cultural intuitions about their family's country and shallow knowledge of the broader Spanish-speaking world. A Mexican-American student may know nothing about Argentina, Spain, or Equatorial Guinea. The classroom is a chance to widen, not narrow, their relationship to the language.

Fourth, linguistic identity. Many heritage learners arrive with linguistic shame, the product of years of teachers and tourists correcting their family Spanish. Potowski (2018) documents this pattern across hundreds of interviews. The classroom either reinforces or repairs it.

The most damaging thing a Spanish teacher can do to a heritage student is treat her family's Spanish as a problem to be fixed.

The vosotros question

A small example, because the politics of it are larger than they look. A heritage student raised in a Mexican family has never used vosotros at home. Her family uses ustedes for second-person plural, formal and informal. The Iberian vosotros is foreign to her in a way that the subjunctive is not.

The instinct of many curricula is to drill vosotros for symmetry with the other conjugations. The pedagogical question is whether symmetry is worth the cost. Drilling vosotros at the same level as ustedes signals that her family's usage is incomplete. The honest framing is the opposite: vosotros is a regional variant she will encounter if she travels to Spain. Useful to recognize. Not central to her Spanish.

The same framing applies to vos (used across the Río de la Plata and parts of Central America), Caribbean Spanish s-aspiration, and the lexical differences between varieties. A heritage student needs to learn that her variety is one of many, not that her variety is wrong.

Differentiation that is not just ‘more work’

In a mixed class, three moves carry most of the weight.

Make every activity dual-track. The L2 students work toward recognition or basic production. The heritage students work toward extension, register-shifting, or genre transformation. The prompt for the L2 group: “Write three sentences about your family using tener.” The prompt for the heritage group, same theme: “Take your three sentences about your family. Now rewrite them in the register you would use for a formal email to your tía who is hosting a wedding. What changes?”

Use authentic texts that map to heritage life. Family WhatsApp threads, regional news articles, recipes in Iberian or Caribbean Spanish, song lyrics with code-switching. These are not novelty materials. They are the actual ecology of language a heritage student lives in.

Build assessment that lets heritage students show range. A rubric that only credits accuracy will tell a heritage student what she already heard at home: that her Spanish is broken. A rubric that credits register flexibility, cultural insight, and sociolinguistic awareness will tell her something different. That her Spanish is a starting point, not a deficit.

What this means for your Monday

Identify the heritage learners in your roster. Most schools do this poorly because the survey question is binary (“Do you speak Spanish at home?”). The reality is a continuum: students who speak Spanish only with one grandparent, students who understand but never speak, students who code-switch constantly. The first useful conversation is a private one with each of them about their actual relationship to the language.

Then redesign one assignment. Pick the one where heritage students typically disengage. Add a parallel track that gives them something to reach for, not something to slow down to. The change is small. The signal it sends is large.
