CTRI is built by people who care. If you have skills that can help us build better textbooks, we want to hear from you.
These are the specific roles we are actively recruiting for. Each role has a clear scope and a direct impact on the textbooks we are building.
Help develop the Mathematics textbook by writing clear, step-by-step worked solutions to practice problems. You will take problem sets and produce clean, student-friendly solutions that guide learners through each concept. Strong Mathematics background required — you should be comfortable with the full SS1–SS3 curriculum.
We welcome contributions from educators, subject specialists, designers, editors, and anyone who shares a commitment to improving access to education. Reach out at hello@ctri.ng and tell us what you can offer.
The CFK Fellowship is a structured volunteer community for young Nigerians making long-term contributions to CFK's work — including CTRI. Fellows receive progression, recognition, and a genuine community of people committed to the same mission. If you want to go deeper than a single volunteer role, the Fellowship is where that happens.
