The literacy by radio project was adopted as an innovative intervention to widening access to literacy programmes for the non-literate groups in Nigeria. Thus, the purpose of this research is to review the contributions of literacy by radio in Nigeria. The researcher adopted the survey design for the study. The population for the study consisted of 2,706 participants and 47 facilitators of the literacy by radio programme in the 10 pilot states in Nigeria. A sample of four states made up of 302 participants and eight facilitators was used for the study. Information collected through Focus Group Discussion (FGD), interviews and content analysis of official documents were used for the study. The data were analysed qualitatively to determine the efficacy of this innovative approach in facilitating literacy in Nigeria. Results showed increased access to literacy programmes through this innovative approach. The pilot project was 88% successful; not less than 2,110 adults were made literate through the project in2017. However, poor funding, lack of enthusiasm and commitment on the part of the technical committee and facilitators, poor signals from radio stations, low community involvement indecision making in the project are major challenges to the success of the project. Improved and timely funding of the project by the Government, setting up of independent radio stations for airing the programmes, customization of materials and proper monitoring and evaluation of the project for greater effectiveness was recommended. Conclusively, literacy by radio has contributed significantly in literacy promotion in Nigeria. [For the full proceedings, see ED666619.]
