Many schools are making changes in their cumulative record systems or are instituting new systems. The reason for this increased interest in cumulative records is their recognized value as a tool in the program of pupil guidance and adjustment. The greatest aid to the pupil can be given only when his rate and trend of development in various intellectual, social, and physical traits is known. The cumulative record of growth in these traits can be preserved in a form for practical use. This bulletin describes the types of cumulative records found in different school systems. Upon the basis of an analysis of their contents and in light of findings of studies of child development, it makes practical suggestions for cumulative record keeping. It suggests ways of recording different types of items and outlines the purposes for which the cumulative record may be employed. The situations in which such records prove valuable vary from the daily adjustment of pupil problems in the classroom to the more formal guidance given by counselors or principals concerning choice of occupations and plans for further schooling.
