As TNTP’s Chief Executive Officer, Dan Weisberg oversees TNTP’s executive team and all aspects of the organization’s operations, strategy, and growth. Prior to becoming CEO in June 2015 as part of TNTP’s long-term growth strategy, Dan was the Executive Vice President for Performance Management and General Counsel. In this role, he built and led a 130-person team to support the efforts of school systems and states nationwide to recruit, develop, and retain effective teachers and principals. The talent, academic, and community engagement practices developed under Dan’s leadership have been responsible for improving the quality of education for over 1 million students just in the past two years. Previously, as Vice President of Policy, Dan helped build TNTP into a leading voice on teacher quality and co-authored TNTP’s acclaimed study on the failures of the nation’s teacher evaluation systems, The Widget Effect, which helped catalyze evaluation reforms in more than 30 states since 2009. He later led the development of the groundbreaking reports, The Irreplaceables (2012), which explored the teacher retention crisis through the experience of the country’s best teachers, and The Mirage (2015), which found enormous resources being devoted to teacher development with little to no impact and set a new path for more engaging and effective teacher support. Most recently, Dan oversaw the development and launch of TNTP’s highest-impact study and most ambitious public engagement strategy with the 2018 release of The Opportunity Myth, TNTP’s report on student experience which has drawn over 100,000 unique visitors and resulted in over 400 briefings, over 4,000 downloads of tools, and over 40 national education leaders signing on to its commitments. Before TNTP, Dan served as Chief Executive of Labor Policy and Implementation for the New York City Department of Education (NYCDOE), the country’s largest public school system. In this role, he led negotiations between the Department and the United Federation of Teachers that resulted in a series of groundbreaking reforms, including the city's highly regarded "mutual consent" system, which gives teachers and schools the primary voice in school staffing. He also led a team responsible for several high-impact talent initiatives such as the redesign of teacher tenure, principal compensation, and principal evaluation, and for providing labor support to NYCDOE’s 1,700 principals. Before joining the NYCDOE, Dan was a Partner in the New York office of Brobeck, Phleger & Harrison, where he led the firm’s east coast labor and employment practice. He holds a J.D. from New York University Law School and a BA in Political Science from Columbia University. Dan sits on the board of several non-profits, including The National Parents Union, Educators for Excellence, The Keystone Policy Center and Blue Engine, and is the proud volunteer coach for the Essex Street Academy High School Mock Trial Team.
