How can governments and educational institutions better involve young people in the policy-making process to ensure their voices are heard and their perspectives are taken into account when shaping education policies?

It is undeniable that students from underprivileged backgrounds, especially in developing countries, where the gap between the haves and the have-nots is wide and  the socio-economic dynamics weigh in on the choice of schools, peers, and somehow teaching staff, find it hard to catch up with the privileged few, who usually do better due to exposure to better learning environments. Until when will socio-economic rather than cognitive capabilities direct students' future development?

Regarding participatory methods of data collection: Are there any other examples of participatory data being used in decision-making processes? If yes, how have the data been used to make policies more inclusive? Furthermore, how does the integration of participatory data into policy-making processes shape/impact the lives of a certain target group (e.g. disabled persons)?
