Mark Day is NAEYC's first Chief of Staff. As a member of the Executive Team, he is responsible for leading strategy, growth, and improvement initiatives to extend the organization's reach and impact in the field.
Mark has spent much of his career supporting mission-driven organizations in the private, public, and non-profit sectors. He began teaching middle and high school science in Philadelphia with Teach For America. He later consulted domestic and international clients across a range of issues at McKinsey & Company. Afterward, he was appointed Connecticut’s first Director of Performance Management & Strategic Planning at the State Department of Education. While there, he refined and implemented the state’s accountability system, co-directed the overhaul of its Statewide Longitudinal Data System, and spearheaded an innovative non-profit, foundation, and school partnership to extend the school day and improve student outcomes.
Since then, Mark has worked at the intersection of education, technology, and the future of work. At EAB, he led the research, development, and launch of student-facing technologies for colleges and universities. Prior to joining NAEYC, he consulted with organizations to better support students and educators through strategic planning, new business development, and digital transformation. He is committed to amplifying the collective voice of NAEYC's members and affiliates, affirming the value of early learning, advancing equity, and promoting the profession.
