1.0 PHILOSOPHY OF THE MECHANICAL ENGINEERING PROGRAMME
The Mechanical Engineering Programme is designed to reflect a FUNCTIONAL philosophy of education.
While seeking to achieve academic excellence and promote the furtherance of knowledge, the mechanical
engineering programme also seeks to aid “¼ the acquisition of appropriate skills, abilities and competence,
both mental and physical as equipment for the individual to live in and contribute to the development of his
society..”
The programme is therefore committed to the production of qualified and competent technicians who will be
able to face the challenges concomitant with the aspiration of the country to be technological developed.
and the Technicians to be self-reliant after graduation
2.0 GOALS AND OBJECTIVES OF THE PROGRAMME
The programme aims at producing mechanical engineering technicians for the nation’s industries,

7
6.0 CURRICULUM STRUCTURE
The structure of the National Diploma programme consists of four semester of classroom, laboratory and
workshop activities in the college, and a semester (3-4 months) of student Industrial Work Experience
Scheme (SIWES). Each semester shall be of 18 weeks duration made up as follows:
a. 15 contact weeks of teaching, i.e. recitation, practical exercise, quizzes, test, etc, and
b. 3 weeks for examinations and registration. SIWES shall take place at the end of the
second semester of the first year.
7.0 ACCREDITATION
The Diploma programme shall be accreditation by the National Board for Technical Education before the
diplomates can be awarded the National Diploma certificates. Details about the process of accrediting a
programme for the award of the National Diploma are available from the Executive Secretary, National Board
for Technical Education, Plot “B”, Bida Road, P.M.B. 2239, Kaduna, Nigeria.

9.0 GUIDANCE NOTES FOR TEACHERS
9.1 The new curriculum is drawn in unit courses. This is in keeping with the provisions of the National Policy
on Education which stress the need to introduce the semester credit units which will enable a student who so
wish to transfer the units already completed in an institution similar standard from which he/she is
transferring.
9.2 In designing the units, the principle of the modular system by product has been adopted, thus making
each of the professional modules, when completed provides the student with technician operative skills,
which can be used for employment purposes self - and otherwise.
9.3 As the success of the credit unit system depends on the articulation of programmes between the
institutions and industry, the curriculum content has been written in behavioural objectives, so that it is clear
to all the expected performance of the student who successfully completed some of the courses or the
diplomates of the programme. This is slight departure in the presentation of the performance based
curriculum which requires the conditions under which the performance are expected to be carried out and
the criteria for the acceptable levels of performance. It is a deliberate attempt to further involve the staff of
the department teaching he programme to write their own curriculum stating the conditions existing in their
institution under which performance can take place and to follow that with the criteria for determining an
acceptance level of performance.
Departmental submission on the final curriculum may be vetted by the Academic Board of the institution. Our
aim is to continue to see to it that a solid internal evaluation system exists in each institution for ensuring
minimum standard and quality of education in the programmes offered throughout the Polytechnic system.
9.4 The teaching of the theory and practical work should, as much as possible, be integrated. Practical
exercises, especially those in professional courses and laboratory work should not be taught in isolation from
the theory. For each course, there should be a balance of theory to practical in the ratio of 50:50 or 60:40 or
the reverse.
10.0 LOGBOOK
A personal Log-book to be kept by the students shall contain all the day-to-day, weekly summary, and
semester summary of all the practical activities from day one to the end of the programme. This is to be
checked and endorsed by the lecturers concerned at the end of every week.
11.0 GUIDELINES ON SIWES PROGRAMMES
For the smooth operation of the SIWES, the following guidelines shall apply:
11.1 Responsibility for placement of students.
9
a. Institutions offering the National Diploma programme shall arrange to place the students
in industry. By April 30 of each year, six copies of the master-list showing where each
student has been placed shall be submitted to the Executive Secretary, National Board
Technical Education, which shall, in turn, authenticate the list and forward it to the Industrial
Training Fund, Jos;
b. The placement officer should discuss and agree with industry on the following:
(a) A task inventory of what the students should be expected to experience
during the period of attachment. It may be wise to adopt the one already
approved for each field.
(b) The industry-based supervisor of the students during the period. It
should be noted that the final grading of the students during the period of
attachment should be weighted more on the evaluation by his industry-
based supervisor.
11.2 Evaluation of students during SIWES. In the evaluation of the student, cognisance should be taken of
the following items:
1. Punctuality
2. Attendance
3. General Attitude to work
4. Respect for Authority
5. Interest in the field/technical area
6. Technical competence as a potential technician in his field.
11.3 Grading of SIWES: To ensure uniformity of grading scales, the institution should ensure that the uniform
grading of students’ work which has been agreed to by all polytechnics is adopted.
11.4 The Institution-Based Supervisor: The institution-based supervisor should initial the log-book during
each visit. This will enable him to check are being met and to assist students having any problems regarding
the specific assignments given to them by their industry-based supervisor.
11.5 Frequency of Visit: Institution should ensure that students placed on attachment are visited within one
month of their placement.
10
Other visits shall be arranged so that:
1) there is another visit weeks after the first visit; and
2) a final visit in the last month of the attachment.
11.6 Stipend for Students in SIWES: The rate of stipend payable shall be determined from time-to-time by
the Federal Government after due consultation with the Federal Ministry of Education, the Industrial Training
Fund and the National Board for Technical Education.
11.7. SIWES as a component of the curriculum: The completion of SIWES is important in the final
determination of whether the student is successful in the programme or not. Failure in the SIWES is an
indication that the student has not shown sufficient interest in the field or has no potential to become a skilled
technician in his field. The SIWES should be graded on a fail or pass basis. Where a student has satisfied all
other requirements but failed SIWES, he may only be allowed to repeat another four months’ SIWES at his
own expense.
12.0 FINAL YEAR PROJECT
Final year students in this programme are expected to carryout a project work. This could be on individual
basis or group work. The project should, as much as possible incorporates basic element of design, drawing
and complete fabrication of a marketable item or something that can be put to use. Project reports should be
well presented and should be properly supervised.
The departments should make their own arrangement of schedules for project work.
