Four specific objectives and four research questions were stated, while four null hypotheses were tested at 0.05 level of significance. Literature and empirical studies were reviewed. From all the literature reviewed, there was hardly available record on study of this nature in the Federal Capital Territory and Niger State, Nigeria. This was the main gap which this study served to fill. Descriptive research survey design was used for the study. Population for the study was 307 business educators while the sample was 184. A structured questionnaire was the main instrument of the study; and out of the 184 administered, 131 were retrieved and found valid. Mean scores were used to answer the four research questions whereas t-test was used to test the four hypotheses. Results of the study showed among others that business educators agreed on the availability of computer applications (such as micro soft word) in teaching business education;business educators utilize computer applications (such as micro soft word) in teaching business education to very great extent; gender influences business educators' utilization of computer applications (such as micro soft word) in teaching business education. Results of the ttest showed that no significant difference exist between the mean responses of business educators on the availability of computer applications (such as micro soft word) in teaching business education. However, t-test statistic revealed that there is significant difference between male and female business educators' mean responses on gender influence on utilization of computer applications (such as micro soft word) in teaching business education. It was concluded that computer applications like micro soft word, micro soft excel, power point, spreadsheet and database are available in teaching business education. It was recommended among others that Management of colleges of education in the Federal Capital Territory and Niger State should endeavour to construct computer technology centre for business education department especially where there is none in order to encourage the promotion of positive disposition on utilization of computer applications in teaching business education.
