Enhancing comparability in early child development assessment with the D-score (2024)
Journal Article
van Buuren, S., Eekhout, I., McCray, G., Lancaster, G. A., Waldman, M. R., McCoy, D. C., Gladstone, M., Cavallera, V., Dua, T., Black, M. M., & Team, G. (2024). Enhancing comparability in early child development assessment with the D-score. International Journal of Behavioral Development, 17. https://doi.org/10.1177/01650254241294033

The lack of a valid and interpretable score to track early child development over time is a primary reason for neglecting child development in policymaking. Many instruments exist, but there is no accepted method for comparing their scores across dif... Read More about Enhancing comparability in early child development assessment with the D-score.

Millions of children under 5 years in low- and middle-income countries fail to attain their development potential with accruing short- and long-term consequences. Low length/height for age (stunting) is known to be a key factor, but there is little d...

Introduction
Ensuring equivalence in high-stakes performance exams is important for patient safety and candidate fairness. We compared inter-school examiner differences within a shared OSCE and resulting impact on students’ pass/fail categorisation....
