Staffing
Academic Staff
The NUC guidelines on staff/student ratio of 1:15 for Engineering and Technology
departments shall apply. However, there should be a minimum of six full-time equivalent
of Staff in the department. There is need to have a reasonable number of Staff with doctoral
degrees as well as sufficient industrial experience. With a minimum load of 15 Units per
semester for students and a minimum of six full-time equivalent of staff in each programme,
staff should have a maximum of 15 contact hours per week for lectures, tutorials, practicals
and supervision of projects.
NUC requirement encourages all academic staff to have PhD degrees, hence appointment
of academic staff is preferably to the Lecturer cadre. Only in exceptional cases are
candidates with great promise appointed to Graduate Assistant and Assistant Lecturer
positions for the purpose of being developed to the Lecturer cadre as registered PhD
candidates.
Academic Support Personnel
Teaching Assistant/Demonstrators to help lecturers in the conduct of tutorials, practicals
and field work. This category of personnel is not expected to be regular staff as they are to
be paid on the basis of approved hourly rate.
Administrative Support Staff
The services of the administrative support staff are indispensable in the proper
administration of the departments and faculty offices. It is important to recruit very
competent senior staff that are computer literate.
Technical Support Personnel
The services of technical support staff, which are indispensable in the proper running of
laboratories and workshop/studios are required. It is important to recruit very competent
senior technical staff to maintain teaching and research equipment. They are also to
undergo regular training to keep them abreast of developments in equipment operation and
maintenance. The minimum of academic staff to technical staff ratio of 5:1 should be
maintained.
Minimum Number of Staff
Subject to the general standards specified by NUC;
there should be a minimum of two PhDs and four M.Eng degree holders full-time academic
staff to mount the programme;
each workshop or laboratory should have an adequate number of staff with the right mix,
such that each unit or section in that workshop or laboratory can run efficiently; and
there should be an adequate number of administrative staff of the appropriate calibre for the
office of the Head of Department to run.
Library
In addition to the university and faculty libraries, the programme must have a departmental
library well-equipped with specialised books and journals in both physical collections and E-
collections (E-Resources) of various types. Various field and research reports of the
programme must also be available in the library for staff, students and researchers.
The library must be connected to subscribed repository of:
national and international institutions
open access sources
professional bodies’ e-learning platforms
relevant international organizations
The library must also have adequate facilities for reading, lending and to include reservation
unit for specialized materials
Classrooms, Laboratories, Workshops, Clinics and Offices
