I2D2 RESOURCE HUB TEAM
Meet The Trusted Team Behind the System
In 2015, Heather Rouse and Cassandra Dorius came together to leverage their combined three decades of experience in education, human services, public health, and integrated data systems.
They brought together leaders from across Iowa’s departments serving young children and their families, secured training and technical assistance to develop Iowa’s model and governance structure, and obtained funding to stand up the system and use it to demonstrate value for informing policy and program improvement. I2D2 was born.
In collaboration with strong Early Childhood Iowa partners spanning diverse systems in the state, this partnership has paved the way for Iowa success. In the words of former ECI Board Chair, the tandem of Rouse and Dorius brings a “palpable level of commitment, a deep understanding of a very complicated system, and a passionate and motivating approach” to the work, which has increased the national visibility of the state of Iowa and Iowa State University as leaders in the use of administrative data systems to inform evidence-based decision making.
In 2019, the dynamic duo was invited to share the successful development of I2D2 at the National Academy of Sciences Committee on National Statistics. With a panel of experts deliberating the value of administrative data, conversations included considerations of how state and municipal integrated data systems could inform national statistical approaches.
