What is the GSTEP Challenge?

The Ghana Science and Tech Explorer Prize (GSTEP) Challenge is a unique opportunity for young people to learn more about innovation, entrepreneurship and Science, Technology, Engineering and Mathematics (STEM). It presents a new and exciting way for young people to engage with Science and Technology through practical learning, developing skills such as problem-solving, presentation skills, communication, teamwork and entrepreneurship skills.

The GSTEP Challenge provides all of the resources to take part, including lesson plans to support the application process, and additional training and mentorship for finalist teams.
