Every English Language Learner arrives in your classroom carrying two heavy loads: mastering new content and mastering a new language — simultaneously. Some students make it look easy. Others hide their struggle so well that by the time we notice, they’re already falling behind.

Whether you’re an ESL specialist running a pull-out program or a mainstream teacher with multilingual students in every period, these five signs can help you catch the students who need more support — before they slip through the cracks. For each sign, there’s a concrete strategy you can use this week.

1. They Avoid Participation — Even When They Know the Answer

What it looks like

The student rarely raises their hand, avoids eye contact when you scan the room, and gives one-word answers when called on. In small groups, they defer to English-dominant peers.

What’s really happening

This isn’t apathy. It’s a production gap — the distance between what a student understands (receptive language) and what they can express (productive language). Many ELL students comprehend far more than they can articulate, and the fear of making a mistake in front of peers shuts them down.

What to do

  • Use think-pair-share with a same-language partner before whole-class discussion
  • Provide sentence frames at their WIDA level (“I think the answer is ___ because ___”)
  • Allow written or drawn responses as alternatives to verbal answers
  • Create low-stakes participation routines (whiteboards, polls, thumbs up/down)

2. High Effort, Low Scores on Standardized Tests

What it looks like

The student completes every assignment, participates in class, and clearly understands concepts during hands-on activities — but their standardized test scores don’t match. Teachers and parents are confused because “they seem to get it.”

What’s really happening

Standardized tests are a reading comprehension test disguised as a content assessment. ELL students often stumble not on the math or science, but on the academic language of the question itself. Words like “evaluate,” “determine,” and “which best represents” are Tier 2/3 vocabulary barriers that mask real content knowledge.

What to do

  • Pre-teach test vocabulary before the assessment window — not content words, but question stem words
  • Practice with scaffolded test prep that shows questions in English with native language support for vocabulary
  • Request testing accommodations your student is entitled to (extended time, bilingual glossaries, separate setting)
  • Use tools like Kuliso’s SOL practice that deliver standards-aligned questions with home language scaffolding built in

3. Strong Verbal Skills But Weak Written Output

What it looks like

The student speaks confidently in conversation, participates in discussions, and explains ideas clearly when talking. But their written work is minimal — short sentences, missing transitions, avoidance of academic vocabulary they use verbally.

What’s really happening

Oral language develops faster than written language for most ELL students. Conversational English (BICS) typically develops within 1–3 years, but the academic written English (CALP) needed for school success can take 5–7 years. The gap between their speaking and writing isn’t a learning disability — it’s a normal developmental pattern that requires explicit writing instruction.

What to do

  • Use oral rehearsal before writing — let students say their response before writing it
  • Provide graphic organizers that bridge oral thinking to written structure
  • Allow students to draft in their home language first, then translate key ideas to English
  • Teach transition words and academic phrases explicitly (“In contrast,” “According to the text,” “This evidence shows”)

4. Code-Switching Under Stress

What it looks like

The student does fine during regular activities, but switches to their home language during tests, timed assignments, or moments of frustration. You might hear them muttering in their L1, or they revert to writing in their home language when they feel rushed.

What’s really happening

Under cognitive load, the brain defaults to its strongest processing language. Stress, time pressure, and fatigue all increase the cognitive demand of operating in a second language. Code-switching under pressure is the brain’s way of saying “I can do this work — just not in this language right now.”

What to do

  • Reduce unnecessary time pressure — if the goal is content mastery, not speed, remove the timer
  • Allow bilingual note-taking and study materials
  • Provide a native language tutoring tool so students can build understanding in their L1 before transferring to English
  • Normalize code-switching as a strategy, not a problem — explicitly tell students “You can think in whichever language works”

5. Test Anxiety Specifically Around Timed Assessments

What it looks like

The student gets visibly anxious before timed tests. Physical signs: fidgeting, asking to use the bathroom repeatedly, starting and restarting questions, leaving answers blank even on topics they’ve mastered in class.

What’s really happening

For ELL students, every timed test has a hidden tax: the time it takes to decode the English, mentally translate, process, formulate a response in English, and write it. A 60-minute test for a native English speaker might functionally be a 35-minute test for an ELL student. They’re not anxious about the content — they’re anxious about the clock.

What to do

  • Advocate for extended time accommodations — this is legally protected under many state ELL policies
  • Practice with untimed or self-paced assessments to build confidence before high-stakes tests
  • Teach test-taking strategies in the student’s home language first (process of elimination, skipping and returning, key word identification)
  • Use practice tools that let students work at their own pace in their home language — building content confidence separately from language pressure

The Common Thread

Notice the pattern? Every sign on this list comes down to the same root cause: the language demand is masking the student’s actual ability. These aren’t students who can’t learn — they’re students whose knowledge is trapped behind a language barrier.

The most effective ELL support strategies share one principle: separate the language challenge from the content challenge. Let students access content in their strongest language while building English proficiency in parallel.

That’s exactly what Kuliso was built to do — from SOL practice in 20+ home languages to AI tutoring that meets students in their native language.
