“ProjectCSGIRLS is a 501(c)(3) international nonprofit organization dedicated to closing the gender gap in computing and technology. Our unique idea of a technology and computer science competition for middle school girls stemmed from the fact that a large chunk of learning and development occurs during the critical middle school period.” (See the statistic above!)
