Most of the existing definitions and measurements of financial literacy have been tailored for developed countries. Although financial literacy and financial behaviour are usually assessed at the household level, the gender dimension of household agents is less explored which may overshadow the women's low level of financial literacy. This paper is a selective systematic review aiming to survey the existing literature on financial training where the focus is on two main issues, namely, financial training and gender disparity in financial literacy. Based on a thorough literature review, we identify research gaps in each of these dimensions. The identified gaps are then used to formulate two promising research ideas. Specifically, the promising research ideas seek to investigate the gender disparity and propose a novel method for financial training.
