Strengthen your evidence-based decisions with dynamic assessment
Become certified in a peer-reviewed, research-validated, Curriculum-Based Dynamic Assessment of oral narratives that helps you identify language learning needs earlier and guide appropriate intervention, particularly for bilingual and culturally diverse learners.


The Challenges Professionals Face in Language Assessment
Practitioners often work with learners whose language profiles are complex. Standardized tools provide important information, but they do not always capture how a child learns or how they respond to support, which are important factors for guiding appropriate support.

-
Standardized scores alone can be difficult to interpret for multilingual learners
-
Static assessments do not capture learning potential
-
Translating assessment results into clear intervention decisions can be challenging
-
Time constraints and heavy case loads make accurate, efficient assessment critical
A research-grounded dynamic assessment that strengthens assessment and intervention planning
The Curriculum-Based Dynamic Assessment (CBDA) provides a structured dynamic assessment of oral narratives that allows practitioners to observe how children learn when provided with support. This approach offers deeper insight into the child as a learner • Objectively measure learning potential, not only current performance. • Identify indicators of DLD risk while distinguishing language difference from disorder. • Gain rich qualitative insight into narrative organization, language comprehension, and responsiveness to mediation. • Generate structured, clinically meaningful reports that support intervention planning and communication with teams. • Automate the assessment process through our online platform using automatic transcription and report generation. • Available in English and French
