The tertiary graduation rate represents the expected probability of graduating for the first time from tertiary education before the age threshold if current patterns are maintained. The age threshold refers to the upper limit for completing a tertiary degree. Age 30 is used as the upper limit for completing bachelor’s degrees and first-time tertiary education overall. At the master’s and doctoral levels, 35 is considered to be the upper age limit for graduation. International students are excluded. The indicator is expressed as a percentage.
