Student Dropout Rate (PI9910)

This metric is intended to capture the percentage of students who left school permanently during the reporting period. For example, if 10 students enrolled in Grade Five and nine have finished as of the end of the reporting period (meaning that one student dropped out), the student dropout rate is calculated as 1/10 = 10%. This metric differs from Student Promotion Rate (PI4924), which captures students proceeding a higher grade of schooling during the reporting period.

This metric aligns with the UNESCO Institute for Statistics Indicator "Dropout Rate by Grade (PR)" (http://uis.unesco.org/sites/default/files/documents/education-indicators-technical-guidelines-en_0.pdf).

This metric is multi-dimensional with regard to the five dimensions of impact. In some contexts, this metric can serve as an indicator of whether the outcome being sought by an investor or organization is occurring (the WHAT dimension of impact). It may also help measure the HOW MUCH Scale dimension, which helps estimate the number of the targeted stakeholders experiencing the outcome. For more on the alignment of IRIS metrics to the five dimensions of impact, see IRIS+ and the Five Dimensions of Impact (https://iris.thegiin.org/document/iris-and-the-five-dimensions/). No single metric is sufficient to understand an impact; rather, metrics are selected as a set across all dimensions of impact. When possible, the selection of metrics to measure and describe the five dimensions should be based on best practice and evidence.
