CBSE is the acronym for Central Board of Secondary Education, while ICSE is the acronym for Indian Certificate of Secondary Education. Both CBSE and ICSE are educational institutions, and whatever certificate you are awarded in any of the institutions can be used anywhere in the world. First of all, CBSE and ICSE are different in terms of syllabus, exam, and other educational activities. Although both institutions are well known but CBSE is highly recognized by the Indian government, while ICSE has not been able to get the government attention.
Also, both institutions have different certificates which would be given to any student who has fully completed all the training processes. However, CBSE certificate seems to have more value than ICSE certificate. CBSE has a more organized syllabus compared to ICSE. The syllabus has been divided into different units, and each unit is to be completed within a stipulated period of time. ICSE, on the other hand, has a heavy syllabus and it is not as organized as CBSE
