Open AccessThat educational system in Nigeria is plagued by crises cannot be doubted. The system has often been criticized for its glaring failure, particularly in ensuring the turnaround of the country which has been the basis for the commitment of financial, human, and material resources to it by government and private sector in the society. It is pertinent to note that many among the educational crises centre round teachers. Many are even arguing that removing teacher related factors from educational crises in Nigeria, the crises are half-solved. In this paper, issues of inadequacy of teachers; low quality teachers; and other aspects of educational crises that relate to teachers were examined. In view of the negative effects of the crises on the educational system, tackling them and moving education forward in the country are imperative in this 21st century. Achieving this feat however calls for the recruitment of additional qualified teachers, motivation, training, re-training, proper monitoring, as well as effective discipline of teachers, among others, as recommended in the latter part of the paper.
