The "Nwa Boi" or “Igba Boi” tradition, meaning "Apprentice," is a cherished customary practice originating from the eastern region of Nigeria. In this tradition, a master takes on the responsibility of teaching and training a younger individual in a specific trade they have honed over the years. This arrangement typically begins with the consent of the apprentice's direct guardian, or parents seeking to secure a promising future for their child. The master assumes full responsibility for the apprentice's welfare, including housing, food, and comprehensive training in the chosen trade. This mentorship typically spans from 3 to 7 years, depending on the complexity of the skill being taught.

At the culmination of the agreed-upon apprenticeship period, during which the apprentice has mastered the craft, the master fulfils their commitment by facilitating the establishment of a similar business for the apprentice, enabling them to become independent entrepreneurs.
