Abstract
In this paper, the attrition rates of students from the
period 1980/81 to 1989/1990, in the Faculty of Science of Addis
Ababa University, were examined. We found that freshmen
attrition rate linearly decrease over time. The dampening effect
of the attrition rate as the students progress from semester to
semester was assessed using two attrition models: the Guttman and
Olkin (1989) model and a re parameterized model that we
formulated. computer programs were prepared to obtain the
maximum likelihood estimates for the underlying parameters in
each model. consistent results were found in the two models; the
progress of Students in consecutive semesters appeared to show
a difference from batch to batch
