The Pittsburgh Regional STEM Ecosystem seeks to understand the STEM learning landscape within a 5-county region surrounding the City of Pittsburgh. The partners within this initiative include the Remake Learning Council, Chevron U.S., Carnegie Science Center, Carnegie Mellon University, ASSET STEM Education, Public Education representatives, the YMCA, and Junior Achievement. Our region has strong partners and experts adept at STEM education programming, professional development, and business partnerships. We seek to develop a collaborative Regional Vision, Goals and Metrics for continuous improvement, based on an understanding of regional gaps targeted at underserved communities. We additionally, seek to articulate the youth STEM pathway between formal and informal experiences.
