Effective administration is a must in the dynamic centres of education: teaching and learning are required to effectively interpret and deploy the nation's education policy and execute curriculum realities that respond to the fatigues of the present and the challenges of the future. The paper, therefore, critically examined the administrative issues relevant in enhancing teaching and learning in terms of preliminary issues of school administration, teachers, and supervisory issues. To achieve this, the study used a descriptive survey research design. The sample of the study consisted of 250 participants (45 principals and 205 teachers) of private and public secondary schools randomly selected from nine local government areas of Rivers state. Three research questions and three research hypotheses guided the study that used a 19-item instrument to gather data from respondents. Descriptive statistics and independent sample t-test were the statistical tools used to analyze the data. The impact of preliminary administrative issues on teaching and learning in secondary school education was quite negative, teacher issues were not considered relevant, and the respondents had negative view of the relevance of supervisory issues of the curriculum to teaching and learning in secondary school education. However, the principals and teachers differed significantly on their mean rating of the impact of preliminary administrative issues, relevance of teacher issues, and the relevance of supervisory issues of the curriculum to teaching and learning in secondary school education respectively. It was recommended among others that secondary school owners--government and private individuals--ensure that administrative issues be given utmost attention for effective teaching and learning.
