doorstroompercentages

Doorstroompercentages describe the share of students who move from one educational level or grade to the next within a defined cohort and time frame. They are used to assess progression efficiency, cohort outcomes, and the equity of educational pathways.

Calculation is typically based on a defined cohort (for example, a specific grade in a school year). The doorstroompercentage equals the number of students who successfully complete the grade or advance to the next level, divided by the total number of students enrolled in the starting grade or level, multiplied by 100. Depending on the context, progression can refer to moving to the next grade within the same level or advancing to a higher level of education.

Applications include benchmarking between schools or regions, policy evaluation, and identifying groups with lower progression to inform targeted interventions. They rely on school administrative data, national education statistics, and other official registers. Doorstroompercentages can reveal bottlenecks in particular grades or transitions, such as from primary to secondary education or within secondary years, and are often examined alongside related indicators like dropout rates and graduation rates.

Interpretation should consider factors that influence progression, such as grade retention policies, transfer patterns, age and entry policies, and data quality. Differences in counting methods or school calendars can affect comparability over time or across contexts. Because doorstroompercentages focus on progression rather than learning outcomes, they provide information about throughput but not necessarily about educational achievement.

Example: if 120 students start a grade and 112 advance, the doorstroompercentage is 93.3%. See also dropout rate and retention.
