The Tomorrow’s Engineers Code unites over 300 organisations working together to inspire and support young people into engineering and technology careers. Signatories commit to four pledges, using them as a framework to help develop their STEM outreach activities: Inspire Connection by creating sustained journeys of inspiration, Drive Inclusion by ensuring access for underrepresented groups, Showcase Engineering and Technology by highlighting career opportunities and benefits, and Improve Impact by continuously learning from and enhancing outreach activities using evaluation data. The Code supports Signatories with free resources, online and in-person events, and opportunities to collaborate and share knowledge.
