A research work entitled: “Determinants of growth on women‟s small scale business in Rwanda: A case of Kicukiro District.” was carried out at Kicukiro District in Rwanda. This study was aimed at investigating the determinants of women‟s small scale business growth with a special emphasize on retailing, hairdressing, tailoring and weaving baskets . The sample size was based on ninety- nine women dealing with a small-scale business surveyed in two sectors of Kicukiro District such as Gikondo and Kicukiro sectors. The findings showed that access to financial capital, access to training, workforce, location, innovation and creativity were the major determinants of business of growth. Findings further indicated the problems affecting business growth such as lack of skills about doing businesses, inadequate training, lack of financial, lack of collateral to enable them secure loans from banks, lack of infrastructure, tax rate and regulations. Nevertheless, some of the major causes of poor/no growth include laws and regulation (tax structure), poor sources of capital, and the use of business‟ resources for private purposes. It was found that the majority of respondents (70%) would like to do business without paying tax. Therefore, it was concluded that the knowledge on determinants of growth on women‟s small scale business is still insufficient in developing countries especially in Rwanda. Finally, the researcher has recommended that there is a need to educate the women‟s small scale business in Kicukiro and in Gikondo sectors about business growth before rushing into their businesses
