Determine the indicator's value by using the following methodology:
1) Obtain school level enrolment data from school registers. If the disaggregated data by groups (e.g. for ethnic origin, language, disabilities or other groups) is not available, then interview school administrators or teachers to get these figures.
2) Contact the local authorities or local leaders to get data on the population of school-aged children in the area and the population of disadvantaged groups. Organisations supporting disadvantaged groups can also be a very good source of information.
3) Calculate the indicator's value by dividing the proportion of disadvantaged group students in school by the proportion of disadvantaged group children in the population.
4) The indicator can reach values from 0 to more than 1. The higher the value, the more equitable the school is for the given group. If it equals 1, then the school ensures equitable participation of the given group.
For example, 5% of Roma children were enrolled in a school in Fush Kosovo. 30% of the local school aged children are Roma. The subsequent calculation is then 0.05/0.30 = 0.17, showing non-equitable participation of Roma children in this school and great potential for improvement.
