ABSTRACT
Board diversity is one of the issues related to corporate governance. In this study, board diversity is measured by five variables, namely women, competency, age, proportion of outsider
and foreign in the members of the board. While the company's value is measured using the ratio of Tobin's Q. The sample was 57 companies included in the financial institutions listed on the Indonesia Stock Exchange (IDX). Based on the competence and the proportion of outsider commissioners found that the proportion of companies with more than the average value of the
sample firms have better firm value. Similarly, a company that has a director member who is less than 50 years old will have a better value of the company. In financial institutions found that the independence of board members is important, the proportion of outsider and proportion of women is more than the average value can have a positive impact on firm value.
