Abstract : This study examined the correlates of usage of Information and Communication Technologies (ICTs) by academic staff in Botswana's colleges of education. It specifically identified and described some selected demographic and job characteristics of the academic staff, determined the levels of availability of and accessibility to ICTs, determined the level of usage of ICTs by the academic staff in performing their academic roles; and empirically established some variables that determines the extent of usage of ICTs. A pre-tested and validated questionnaire was used to elicit information from all the 265 academic staff across the four colleges of education in country. Data collected were subjected to descriptive statistics, such as frequencies, percentages, means, and standard deviations, as well as inferential statistics like Analysis of Variance (ANOVA) and Pearson correlation using SPSS. The findings revealed that most (57%) of the respondents were female with the mean age of 51.6 years. Most (55.1%) of the respondents are married, and 84.9% obtained a master's degree. The mean experience of the respondents was 25.45 years with standard deviation of 7.4 years; and the mean income per month was BWP 24,014.83 with standard deviation of BWP 3,016.22. In the order of importance, the results showed good congruence between mean scores of availability of and accessibility to Microsoft teams, Interactive whiteboards, You Tube, Laptop and Projectors ranking between 1st and 5th, while Microsoft word, WhatsApp, Microsoft excel, Microsoft PowerPoint, Desktop computers are ranked lowest between 10th and 14th. Designation (F=2.688; p 0.047), age (r = -0.170, p = 0.007) and experience (r = -0.171, p = 0.008) of the respondents; and availability of ICTs (r = -0.356, p < 0.01) and accessibility to ICTs (r = -0.322, p < 0.01) of ICT resources were empirically established as correlates of ICTs usage. It is then recommended that the government and the colleges authorities provide adequate infrastructure for enhancing access to Microsoft Teams and other important ICTs for effective performance of the academic staff roles.
