?To ensure validity and reliability of the study findings, Creswell, (2007), Hoyle et al. (2002) and Patton (2002) argue for triangulation as a strategy for improving validity and reliability of research. For this study, observation, document search and interviews were used to ensure validity of the findings.The reliability of interviews for this research was observed through pilot testing. This was done to ensure that no information was missed from the respondents. Questions that were not clear to the respondents were noted and rectified.
