Attached is very interesting reading... "Taking the shine off the School story" From SA Institute of Race Relations
The above link states the requirements for NSC as:
The minimum requirements are that a candidate ‘achieves’ 40% in three subjects,
one of which is their home language and 30% in three other subjects.
Concluding that an educational system promotes mediocrity on the basis of percentages required for a pass would not necessarily be a valid argument. One would have to assess syllabus content and the level at which the examination paper is pitched as well. The proof of the pudding lies in the level of literacy and numeracy that the schools produce and in the number of students achieving adequate knowledge to enter the job market or tertiary education. Here our education system fails badly.
