This paper illustrates the application of life table techniques to data on school enrollments as a means of estimating school life expectancy. The school life tables which are derived are double decrement tables which show the joint effects of death and school dropouts on school attendance patterns. Such tables drawn up for 1950–52 and 1957–59 show the improvements in school retention by age during the last decade. Modifications of this type of analysis which would incorporate the probability of other phenomena occurring and extend the applications to other population groups are suggested.
