The study progressed as guided by a specific research question To what extent do the ISTP Multiplicators use interpersonal skills in supervision of instruction This research question was transformed into a research hypothesis. The case study research design was used with proportionate and random sampling techniques respectively to ensure that respondents from all the schools were represented equally. Questionnaire for teachers was the instrument used for data collection. Data were analysed using statistical packages for social sciences SPSS version 21.0 for windows. Results were reported using descriptive statistics. Chi square and student t tests were used to determine relationships between respondents demographic characteristics and their view on some attributes of the ISTP Multiplicators. The decision rule was to reject the null hypothesis where the computed mean was statistically significantly greater than the expected value and accept the alternative hypothesis. Following this rule all the alternative hypotheses were rejected and the null hypotheses accepted. Recommendations were made to the Education secretary of the CBC, the ISTP Coordinator, the Principals and teachers of the schools concerned, the ISTP Multiplicators in order to improve performance levels of the ISTP Multiplicators.
