The study assessed principals’ use of management information systems (MIS) in managing public secondary schools in Central Senatorial Zone, Kaduna State. The study was guided by three research questions with corresponding 3 objectives and 3 null hypotheses. The research design used for this study was descriptive survey research design. The total population of the study consisted of 168 principals and vice principals drawn from all 168 public senior secondary schools in the central senatorial zone of Kaduna State. The sample size of the study consisted of 84 respondents drawn from 84 secondary schools using a simple random sampling technique. The researcher’s self-developed instrument which consisted of 24 items was used for data collection. The instrument was validated and it yielded 0.63 as the logical validity index. The instrument was pilot tested on 20 principal and vice principal and the coefficient of internal consistency of 0.72 was obtained. Descriptive statistics of mean and standard deviation were used to answer the research questions while Pearson product moment correlation was used to test all the hypotheses at a 0.05 level of significance. The major findings of the study indicated that MIS is effective in managing various aspects of staff and students' records and shows a significant relationship between MIS use and the management of students’ records, administrative competence, and teachers’ computer skills in recording students’ scores in public senior secondary schools in Central Senatorial Zone of Kaduna State. This implies that no meaningful records management process can ignore the impact of MIS in effective records management since it is clear that information creation, storage and retrieval have gone from pictorial representations on the walls of caves and artefacts to the invention of writing and computers. The study recommends that efforts should be intensified by government and stakeholders in education in collaboration with the School Based Management Committee (SBMC) to introduce and ensure its implementation of the use of modern technology such as Education Management Information System (MIS) for improved method of record management of students in public senior secondary schools of Central Senatorial Zone, Kaduna State.
