Coverage: Mathematics Proficiency Level 3 is the share of children who attain the specified level of mathematics proficiency, treated as an opportunity in calculating the Human Opportunities Index (HOI). The coverage rate measures the overall access rate for this opportunity across the relevant population. It does not show whether access is distributed equally among groups defined by circumstances such as family background or location; that distributional dimension is captured separately in the HOI.
