    7.0 DEPARTMENT ACADEMIC POLICY AND REGULATIONS

    7.1 COURSE CREDIT SYSTEM

    (i) The academic policy of the Eastern Polytechnic, Port Harcourt, is based on the existing standards of the National Board for Technical Education (NBTE) which aims at achieving uniformity in all polytechnics in the country. The form of curriculum organization whereby the work/syllabus in a particular programme of studies are divided into course in prescribed section of teaching and study, each of which is separately examined and assessed.

    (ii) The course credit system seeks to avoid package repetition or instructional components earlier assessed as passed, and which may on the other hand improve performance in the instructional components earlier asssessed and failed. This will provide specification in the work load by enabling more precise specification of the different requirements and the ancillary course of various instructional programmes.

    7.2 DEFINITION OF BASIC TERMS

    (a) “Session” means an academic year as determined by the Academic Board which shall normally be of two semesters.

    (b) “Semester” means period of about 18 weeks including 15 contact weeks.

    (c) “Contract Hour” is defined as the period of classroom, laboratory, workshop or fieldwork interaction between a tutor and students for academic instruction and supervision.

    (d) “One Credit” is defined as one labour of lecture, or tutorial per week per semester or two three hours of field, laboratory, passed in particular a programme of studies.

    (e) “Compulsory Course” are courses that must be taken and passed in particular a programme of studies.

    (f) “Elective Courses” are optional courses that once chosen would have to be passed.

    (g) “Examination” means a formal written, spoken or practical test.

    (h) “Grade Point” (GP) is derived from the actual percentage raw score for a given course; the score is then converted into a letter grade and a grade point.

    (i) “Grade Point Average” (GPA) is the ratio of the total credit points calculated by multiplying the course grade point by the semester hour value of the course.

    (j) “Cumulative Grade Points Average (CGPA) is the ratio of the total credit points for the present and previous semesters to the total numbers of the semester hours for the present and previous semester. In other words, it is the up-to-date mean of the grade that indicate the student’s over all performance at any point in the training programme.


    8.0 METHODS/ILLUSTRATIONS FOR COMPUTATION OF STUDENT OVERALL PERFORMANCE

    (i) Grade Point (GP)

    Grade point obtained by multiplying the credit hours assigned to a particular course by hours point obtained in the examination of that course. For example, if Electrical Graphics property law carries 4 credits and a student obtained 80% which is 4 points, his grade for property law will be 4×4 = 16.

    (ii) Computation of Grade Point Average (GPA)

    The overall performance of each student shall be determined by means of grade point average obtained by awarding credit points in respect of each course on the basis of semester hour of the course multiplied by the numerical value of the grade obtained. The grade Point Average is then the total number of credit points divided by the total number semester hours. For example, if a student scores A (80%), BC (50%), B (60%), and C (40%), in four subjects which carry 3,2,1, and 3 credit hours respectively, his/her GPA will be worked out as follows:-

    Score Grade Credit Hours Points Total Point
    A 3 4.00 12.00
    BC 2 2.50 5.00
    B 1 3.00 3.00
    C 3 2.00 6.00
    TOTAL 9 26.00
    GPA = 26.00/9

    =

    2.89

    If the credit hour attached to the subject were 12.3.9. and 6 respectively, the student’s grade point average will be 3,15 as shown below:

    Score Grade Credit Hours Points Total Point
    A 12 4.00 48.00
    BC 3 2.50 7.50
    B 9 3.00 27.00
    C 6 2.00 12.00
    TOTAL 30 94.50
    GPA = 294.50/30

    =

    3.15

    In the above example, the POINT AVERAGE of the students has increased because of the change in the credit hours attached to the various subjects and because he/she scored highly in the subject with the highest credit hours, since this will step up his/her grade point average, while low score in the highest credit subjects will cause a sharp drop in his/her Grade Point: Average.

    (iii) Cumulative Grade Point Average (CGPA)

    The calculation of a Grade Point Average obtained by a student in two or more semesters is referred to as the student’s Cumulative Grade Point Average. It is simply a weighted average. For example, a student’s scores for two semesters were as follows:

    1ST SEMESTER

    Subject Score Credit Point Total Point Grade Hours
    English A 4 3.00 12.00
    Mathematics AB 4 3.50 14.00
    Sociology C 2 2.00 4.00
    Law CD 3 1.50 4.05
    Graphics BC 4 2.50 10.00
    TOTAL 17 51.00
    GPA = 51.00/17 =2.62

    2ND SEMESTER

    Subject Score Credit Point Total Point Grade Hours
    English A 4 3.00 16.00
    Mathematics AB 4 3.50 14.00
    Sociology D 2 1.00 2.00
    Law B 3 3.00 9.00
    Graphics BC 4 2.50 10.00
    TOTAL 17 51.00
    GPA = 51/17 =3.00

    Cumulative Points Average = (1st Semester grade GPA + 2nd Semester GPA)/2 =(2.62 + 3.00)/2 = 5.62/2 = 2.81

    (iv) Graduating Grade Point Average (CGPA)

    The final or fourth semester examination of the National Diploma or Higher National Diploma is regarded as the National Diploma Examinations.

    The examinations are externally moderated. A 40% weight is attached to the final semester Diploma examinations.

    The three initial semesters are granted 20% weight each. Therefore, the CGPA is calculated as showed by the example below.

    1st Semester 2nd Semester 3rd Semester 4th Semester CGPA Remark
    GPA 20%0.59 (293)

    0.59+GPA 20%0.50 (2.50)

    0.50+GPA 20%0.50 (2.50)

    0.50+GPA 40%1.24 (3.09)

    1.24= 2.83100%2.83Lower Credit

    This places the students diploma in the lower credit class.

    9.0 EXAMINATION EVALUATION AND GRADING PROCEDURE

    9.1 EVALUATION PROCEDURE

    (a) The overall assessment of the student’s performance in each course offered in the semester shall be based on a semester examination written at the end of the semester, together with the continues assessment of the course work.

    Course work is define as the sum total of laboratory/workshop/field work/class tests project work (where applicable) and all assignments during the semester.

    (b) The Head of department is obliged to release the course work scores in respect of students from his/her department a copy of which shall be ———–to the academic officer for record at least three (3) days to the commencement of the examination.

    a. Assignment (minimum of 2) 5%

    b. Class tests (minimum of 2) 15%

    c. Laboratory practical/workshop practice 20%

    d. Semester examination 60%

    Total 100%
