Abstract: Research shows responsive caregiving enhances children's brain development, with parental knowledge predicting positive behaviors and outcomes. However, knowledge varies widely across educational levels, highlighting the need for targeted interventions. Despite evidence that this knowledge can be improved, no comprehensive metric exists for efficient assessment. We introduce SPEAK (Survey of Parent/Provider Expectations and Knowledge), a computer-adaptive tool grounded in item-response theory that we created, to address this gap by measuring parental and educator knowledge across development domains with precision and speed. This paper details SPEAK's development, including domain construction, cognitive interviewing, expert review, psychometric calibration, and validity evidence. SPEAK offers a flexible, scalable solution for clinical, educational, research, and policy settings. By identifying knowledge gaps, it enables tailored interventions, supports professional development, and informs policy, ultimately improving parent-child interactions and child outcomes. Our tool bridges critical gaps in assessing child development knowledge, advancing research and cross-sector collaboration to promote early childhood development worldwide.
