The great growth in college enrollments, the changes in the availability of positions for college graduates, and the development in the science of testing go hand-in-hand in making the problem of the prediction of college success of greater importance than ever before. This bulletin brings the attention of educators upon the work which has been done in this field and the techniques which may be used to advantage in solving these problems. In doing this it brings up to date the practices in this field since the publication of Colvin and MacPhail's "Intelligence of Seniors in the High Schools of Massachusetts" by the Office of Education in 1924. The need for the advancement in the methods used for the guidance of entering college students is evident in our modern life. Education must more and more base its practices on the findings of statistical and experimental studies. This bulletin points the way for increasing the accuracy of our knowledge about the possibilities of achievement of our entering college freshmen. A bibliography is provided. (Contains 31 tables, 1 figure and 7 footnotes.) [Best copy available has been provided.]
