Abstract
The paper highlighted the meaning of
supervision including supervision of
instruction. It mirrored the purposes of
supervision and the qualities of a supervisor.
The impediments to effective supervision were
highlighted. The paper further established the
meaning of quality assurance and the
relationship between instructional supervision
and quality assurance. In conclusion, it was
made clear that quality assurance can only be
guaranteed and the purposes of secondary
education achieved under fertile conditions,
one of which is effective supervision of
instruction in Nigerian secondary schools.
Suggestions were then put forward.
All organizations including churches,
corporate enterprises and schools exist
essentially to achieve certain stated objectives.
To ensure the achievement the stated objectives,
such organizations are guided by certain
principles and mechanisms in order to ensure
success. One of such mechanisms includes
supervision. Secondary education is of course a
very important segment of the education ladder
both in Nigeria and elsewhere. This is because
secondary education not only produces middle
level manpower for the economy, it also prepares
its beneficiaries for tertiary education.
