Ensuring equal conditions of access and success for all higher education students is a challenging task for educational systems and institutions. Understanding the students' perspectives and needs regarding educational policies and institutional practices in higher education can be an important contribution to improving the quality of education. This paper aims to identify the main obstacles faced by students and their proposals for the improvement of policies and institutional practices in the Portuguese higher education system to promote access and success for all students. By using a mixed-methods approach, we gathered responses from 1,292 students enrolled in 56 HEIs. Data was analysed through content analysis with a pre-existing grid comprising three dimensions: socio-economic, educational and institutional. Descriptive statistics were carried out for the quantitative data. The results revealed socio-economic factors were the most frequently mentioned as needing improvement, followed by the educational and institutional factors. The results allow concluding that institutional practices and educational policies are directly related. Thus, the institutional and political improvement actions should be seen in a holistic and integrative way, integrating actions to enhance the students' socio-economic, educational and institutional conditions.
