ShareStats - The open statistics assessment itembank

Abstract

ShareStats is the world’s largest public repository of open-source statistics assessment items, developed to support high-quality, data-informed education. This collaborative initiative brings together multiple Dutch universities and universities of applied sciences with the shared goal of improving the quality, efficiency, and fairness of statistics assessment. All materials—primarily multiple-choice questions—are openly licensed, peer-reviewed, and psychometrically validated, ensuring they are reliable and reusable across educational contexts. Hosted publicly on GitHub, ShareStats invites anyone to access, adapt, and contribute to its growing item bank. By promoting transparency, collaboration, and inclusivity in education, ShareStats embodies core open science values. It provides a robust resource for teachers, researchers, and policymakers to develop better assessments and advance statistical literacy on a broad scale.
