CGPA vs iCGPA

CGPA is Cumulative Grade Point Average whereas
iCGPA can be interpreted as Integrated Cumulative Grade Point Average.

CGPA results are shown as grades per subject such as Physics, Biology, Chemistry etc that make up the programme. There are so many subjects that make up a course, more than 30 subjects for a Bachelor course.

iCGPA results are shown as grades per programme outcomes such as knowledge, problem solving, team work, ethics, communication skills, lifelong learning. There are not many of these outcomes. Under MQA, Malaysia Qualifying Agency, it requires a minimum of 8 Programme Outcomes to be shown to have been achieved.

In fact MQA requires educational institutions to achieve learning outcomes such as documented by the iCGPA objectives, instead of just by subjects as required by CGPA.

You may argue that CPGA implements only the Knowledge outcome of the iCGPA but actually many components such as the writing of Thesis also measures communication and critical thinking skills, but they are averaged in the marking scheme in order to come up with the CPGA points.

iCGPA breaks down the marking schemes into learning outcomes. These learning outcomes should support programme outcomes. You may argue also that iCGPA is just a different marking scheme.

Since there are only a few programme outcomes, the iCGPA results can be presented as a spider web concept map. No, Spider Web diagram is not invented in Malaysia for the iCGPA.

I had attended a forum and question and answer sessions on whether iCGPA is to be implemented.
There was a vote, and most do not want iCGPA to be implemented. It means that they do not want to have MQA certification.
