This document discusses educational indicators and how they are used to measure and analyze education systems. It identifies several key types of indicators: 1. Access indicators measure whether school facilities are adequately utilized using factors like population, distance to schools, and travel time. Common access indicators include percentages of habitations served by primary schools. 2. Coverage indicators relate enrollment to the eligible population. Examples include admission, enrollment, and transition rates which are calculated by dividing enrollments by target populations. 3. Internal efficiency indicators measure student flows and rates of promotion, repetition, and dropout within education levels. Transition rates specifically track flows between education levels.
