An analysis of efficiency in senior secondary schools in the Gambia 2006 – 2008: Educational inputs and production of credits in English and Mathematics
This paper employs a stochastic production frontier model to assess the efficiency of
the senior secondary schools in the Gambia. It examines their efficiency in using and
mixing the educational inputs of average teacher salary, average teacher education,
average teacher experience and students to teacher ratio in producing the number
of students scoring credit and above in English and Mathematics. The schools are
categorized into three types: the Government schools, the subsidized schools and
the private schools. The paper finds no evidence that the private schools are different
from the subsidized schools, but there is robust evidence that the private schools are
significantly different from the Government schools. The average teacher salary is
found to be irrelevant to the student performance, whereas high average teacher experience
significantly improves student performance, and high student-to-teacher ratio
significantly negates the student performance. Private schools appear to be the most
efficient in 2006, but from 2007 to 2008, the performance of the schools in general
is found to be highly volatile and unpredictable. Only one school emerges to consistently
maintain a superior efficient performance throughout the three years studied.
