Under Timothy’s tenure as President, TNTP has become a leading source of innovative research and a respected independent voice on teacher quality issues. He played a key role in the publication of The Widget Effect (2009), an acclaimed study detailing the flaws in teacher evaluation. The report informed the federal government’s $4.3 billion Race to the Top initiative and helped catalyze legislation in more than 15 states. More recently, he participated in the writing of The Irreplaceables (2012), which explored the teacher retention crisis through the experience of the country’s best teachers.
In 2012, Tim and CEO Ariela Rozman were co-recipients of the Harold W. McGraw, Jr. Prize in Education for their leadership at TNTP.
Timothy began his tenure at TNTP in 2001 with the New York City Teaching Fellows, a program he helped grow into one of the leading providers of new teachers in the nation's largest district. Nearly 10,000 NYC Teaching Fellows currently work in city classrooms, accounting for 1 in 5 science teachers, and 1 in 4 math and Special Education teachers.
Before joining TNTP, Timothy served as a Teach For America corps member at Northeast Middle School in Baltimore. He holds a MA in Teaching from Johns Hopkins University and a BA in American Studies from Northwestern University.
