The Scratch development team includes:

Mitchel Resnick, John Maloney, Natalie Rusk, Evelyn Eastmond, Amon Millner, Jay Silver, Eric Rosenbaum, and Karen Brennan in the Lifelong Kindergarten group at the MIT Media Lab. The team works in an interactive, iterative, loosely-organized style, with each team member contributing to many different parts of the project.

Andrés Monroy-Hernández in the Lifelong Kindergarten group, who leads the development and management of the Scratch website (and the ScratchR platform underlying it).

Brian Silverman and Paula Bonta of the Playful Invention Company, who contribute to design, development, and exploration of new directions.

Yasmin Kafai (Univ. of Pennsylvania) and Kylie Peppler (Indiana Univ.), who are conducting research studies with Scratch.

We would like to give special thanks to:

Others in the Lifelong Kindergarten group who have contributed to the Scratch project, including: Tammy Stern, Dave Feinberg, Margarita Dekoli, Han Xu, Leo Burd, Lis Sylvan, Oren Zuckerman, Ioana Fineberg, Rachel Garber, Chris Garrity, and many MIT undergraduates and interns, including Nick Bushak, Paul Medlock-Walton, Ubong Ukoh, Christine Kim, Daniel Strimpel, and others.
