STEM Professional Networks


We aim to promote and expand access to STEM education, by working in partnership to increase collaboration, reduce duplication of services, and identify and close gaps in STEM education.

Philadelphia STEM Ecosystem logo


In 2015, the Philadelphia STEM Ecosystem, in conjunction with 21PSTEM and the City of Philadelphia’s Mayor’s Office of Education, launched the Philadelphia STEM Ecosystem— an effort to bring together the diverse and divergent community of STEM providers. Today, the Ecosystem is more than 800 members strong.

As the backbone organization, PEF staff set the vision and mission, facilitate communication and connections among Ecosystem members, and ensure the continuance of the local Ecosystem movement.

Philadelphia STEM Equity Collective

The Philadelphia STEM Equity Collective (PSEC) was established in 2020 to cultivate STEM equity, access, and inclusion in STEM career pathways for Philadelphia students who are traditionally underrepresented in STEM occupations. Using a collective impact model and harnessing the resources of the Philadelphia STEM Ecosystem, the Philadelphia STEM Equity Collective is an initiative by GSK in collaboration with the Philadelphia Education Fund through its Philadelphia STEM Ecosystem.
