Abstract: Teenage pregnancy involves females under the age of 18 and it is interplay of several factors social, biological, economic and psychological. Teenage pregnancy has been widely studied, but attention in relation to Africa has been largely limited to its prevalence. In particular, little work has been done on the effect of teenage pregnancy on academic progression, since the girls’ enrolment in Ainamoi sub-county is fluctuating.Walberg’s theory of educational productivity and Positive and the roots of motivation theory was the theoretical framework that underpinned the study.
