A study of the vocabulary and comprehension scores of juniors and seniors at Marygrove College was conducted during the winter term of 1983 in order to determine the reading levels needed for success in upper division courses. Because the research was designed to determine the reading levels needed for successful study, students on academic probation or taking more than one developmental course were eliminated from the potential sample. Sixty-six students were given the Nelson Denny Reading Test, Form F; three were subsequently eliminated, leaving 24 seniors and 39 juniors in the sample. Juniors had an average college sophomore reading level, and seniors had an average reading equivalent of late college freshman year. However, the scores encompassed a very wide range, indicating that a wide variety of reading levels is applicable for successful study at the college level. It appears that juniors and seniors who have taken developmental reading never attain the reading level of those students who did not take such courses, but they do persevere. Therefore, it might be better to admit students with reading deficiencies and then provide the appropriate educational support to enable them to achieve a meaningful liberal arts education. Numerous tables and charts provide participant test scores and other data. (DF)
