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 equivalents 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, practical’s 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, practical’s 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: 1. there should be a minimum of two PhDs and four M.Eng degree holders full-time academic staff to mount the programme; 2. 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 3. there should be an adequate number of administrative staff of the appropriate caliber for the office of the Head of Department to run. Student/Staff Ratio The minimum staff-to-student ratio should be 1:15 from 200 level to 500 level. 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: 1. institutions (national and international); 2. open access sources (Agora, Science direct, OARE, HINARI amongst others); 3. professional bodies’ E-learning platforms; and 4. Relevant international organisations; The library must also have adequate facilities for reading, lending and reservation of specialised materials.
