A digital platform to understand children’s language-learning profiles.

DECILE (Dispositivo de Evaluación de la Comunicación Infantil en Lengua Española) is an online assessment platform designed to evaluate oral language comprehension and production in Spanish-speaking children aged 3 to 12. Built in Argentina from psycholinguistic research, DECILE helps researchers, educators, and clinicians identify how children understand language — and how their learning profiles differ.

  • Designed for children .

  • Grounded in research.

  • Built for Spanish-speaking contexts.

Our Vision

DECILE envisions a world where every child—regardless of linguistic background or ability—receives the support they need to develop strong communication skills. By leveraging cutting-edge psycholinguistic research and innovative digital tools, DECILE aims to ensure that no child is left behind due to language-related barriers.

Our Mission

To identify diverse language learning profiles early, reduce biases in assessment, and equip educators, health practitioners and caregivers with actionable insights. By bridging the gap between science and practice, DECILE strives to foster equitable learning opportunities, empowering all children to connect, express themselves, and reach their full potential.

Why DECILE matters

Many Spanish-speaking children do not have access to scalable, engaging, research-based tools for assessing oral language development.In Argentina, schools and clinicians often rely on paper-based tests, tools normed in other countries, or local adaptations created separately by each institution. These approaches are time-consuming, difficult to compare across settings, and often fail to reveal each child’s specific language-learning profile.This gap is especially important for deaf and hard-of-hearing children. Their language development is shaped not only by chronological age, but also by hearing age, access to hearing technology, communication experience, and educational context. Standard assessments rarely capture this complexity.DECILE was created to provide better information, earlier: which children may be at risk, which skills are affected, and which children share similar profiles of strengths and difficulties.

What DECILE does

DECILE evaluates oral language skills through child-friendly digital tasks. Children interact with playful activities guided by DECILE’s character, Popi, while the platform captures research-grade data.

  • Sentence comprehension

  • Question compprehension

  • Narrative production

DECILE currently assesses:

  • Sentence comprehension

  • Narrative production

  • Children profiles

  • Research and school data
