Pre-K programs serving dual language learners often rely on Spanish translations of English assessments to measure student progress. However, educational experts warn that direct translation creates significant measurement errors that misrepresent a child's true cognitive abilities. To accurately assess young learners, schools must transition from translated tools to true bilingual assessments developed in parallel across both languages.
What Happened
Educational non-profit Khan Academy Kids recently drew attention to the sharp distinction between "translated" and "bilingual" assessments. According to a Khan Academy blog post, direct translation introduces biases that look like child performance issues but are actually measurement failures.
During a webinar, Dr. Sandra Barrueco of the Catholic University of America explained that inappropriate assessments lead to high rates of misdiagnosis. In these cases, typically developing bilingual children are incorrectly flagged as having developmental delays, while other multilingual children who genuinely need language support are missed entirely.
The Bigger Picture
Standardized early childhood language tools in North America frequently rely on monolingual, Western-centric norms, according to a synthesis in Landscapes for Learning. This misalignment risks over-identifying or under-identifying developmental language disorders in multilingual children, who are evaluated under systems built around monolingual norms.
Direct translations fail because words carry different difficulty levels and grammatical complexities across languages. For example, a simple English past tense sentence like "she hoped it would happen" translates into the complex subjunctive in Spanish (esperaba que pasara), a grammatical structure that preschoolers do not yet fully control.
Regional vocabulary variations also penalize students. A strawberry is called a frutilla in South America, a fresa in Mexico, and a fresón in Spain. Research published by Comprenders Docs shows that a child's cultural and regional background heavily skews cognitive test scores. This means a low score on a translated assessment might only reflect a lack of exposure to the specific dialect used by the test developer, rather than an actual cognitive deficit.
To address these inequities, researchers are building adaptive, fair testing tools. For instance, the ROAR Palabra lexical decision task uses item-response theory to create a culturally adaptable Spanish reading measure that prevents regional vocabulary from artificially lowering scores. Bilingualism itself has dual developmental effects; a study in Discover Education notes that while bilingual children show a 16% advantage in phonological accuracy and stronger executive functions, they may temporarily have 12% to 18% smaller lexicons per language.
What This Means for Families
If your child is assessed only in English, or with a poorly translated Spanish test, their scores may reflect their English acquisition level rather than their actual math or reading skills. For instance, a math task where a child must count to five in English might flag them as struggling, even if they can routinely count to twenty in Spanish at home.
To get an accurate picture of what a child knows, assessments must be built simultaneously in both languages from the start, using equivalent difficulty levels. True bilingual assessments allow children to show their skills in whichever language they know best.
What You Can Do
Parents can start by asking schools whether assessments were built as bilingual tools from the beginning or simply translated from English. Supporting the child's home language is also valuable, as supporting heritage languages is linked to stronger long-term literacy and socioemotional outcomes. Finally, families can advocate for adaptive tools like ROAR Palabra that account for regional vocabulary differences instead of penalizing diverse Spanish dialects.
