About Us
Purpose
In our lab, we research, develop, validate, and apply IGDIs to support data-based decision making by educators, early childhood professionals, caregivers, and others to help improve early childhood outcomes.
In addition to a strong foundation in psychometric research, we also leverage technology to quickly design, test, and refine assessments. This technology infrastructure allows us to test new assessment content quickly and at a lower cost.

Mission
Our mission is to bring all young children's assets into focus through rigorous research, equity-centered design, and community engagement.
Values
Antiracist and Equity-Focused
We infuse our work with self-reflection, humility, un-learning of harmful practices and center the experiences of children with marginalized identities to equitably elevate all children’s outcomes.
Community-Centered Collaboration
We are collaborative - we don't do the work without grounding in our communities and engaging with partners in meaningful ways. We work WITH our collaborators, not just for our collaborators.
Multilingual Engagement
We are committed to honoring and engaging multilingual communities and children.
Balanced Research
We are committed to balancing psychometric rigor with lived experiences to provide practical tools that inform instruction. We value many different forms of expertise.
Strength-Based Approach
We are strength-based, focusing on highlighting and honoring strengths inherent within each individual.
Continuous Learning
We are learners- we make mistakes, we learn and adjust, and are always updating our approach and measures.
Innovation-Driven
We are innovators- striving to leverage technology and new solutions to design better products more quickly and at lower costs.

Directors and Staff

Erin Lease, Ph.D.
Director of Research Innovation
I bring deep experience in child development, education, and practical innovation to my role in supporting ed tech partnerships. With a Ph.D. in Education and a Master’s in Child Development, I also have applied experience in children’s mental health and home visiting. I understand the nuances of bridging research and practice. I'm especially interested in cost-effective, scalable tools that actually make teachers’ lives easier—and support student learning. I act as a bridge between data teams and schools, helping big ideas translate into real-world impact. I'm endlessly curious, allergic to jargon, and always up for solving a good challenge. Most of all, I believe teachers have the hardest, most important job on the planet. My goal is to make their work easier, not harder—and to build solutions that respect their time, talent, and impact.

Alisha Wackerle-Hollman, Ph.D., NCSP
IGDILab Executive Director, Associate Research Professor
I am an educator. A farmer's daughter. A mother. A researcher. A scholar. A first generation student. These pieces of me make up the story that fuels my work.
I have a deep commitment and passion for early childhood education. In my earliest moments of my career, I learned many perspectives about raising and nurturing children. First as a preschool teacher, then as an associate director of a preschool, then a para-professional for young children with Autism, then as an early childhood special education teacher, then as a mother, then as a school psychologist, and then as a research professor.
As an educational psychologist, my interests intersect in ways that support early childhood development, with an interest empowering caregivers, learning about child development, and doing that in a way that improves children's outcomes. This facet intersects with a direct interest in child development and how we understand their growth through assessment, and how to help educators use assessment data to modify their instructional strategies through data-based decision making.
In all my work I strive to be grounded in community. I recognize my own identity and positionality and how being a white woman with a variety of indicators of priviledge afford me power, and I maintain a commitment to using that power to engage in community-based participatory research. This work has led me to invest my time and energy in learning to become an advocate, expert, and collaborator with multilingual communities and communitites that have been marginalized, leading to my work with Latine, Hmong and Black and African American communities.
As the executive director of IGDILab, I stand on the shoulders of many great scholars who started this work - Stan Deno & Scott McConnell - to build measures that have evolved through a frame of equitable assessment design. These measures, the Individual Growth and Development Indicators (IGDIs), Individual Growth and Development Indicators- Espanol (IGDIs-E), and Hmong IGDIs are now used in classrooms across the nation and help educators learn about their student's language and early literacy skills through technology based resources like IGDI-APEL and IGDI-APEL Espanol.
