As soon as results are announced, the primary thing which crosses the minds of ICSE students and their parents is not only "How many marks have I scored?" but, more importantly, "What does that translate into in terms of grades?" This is quite an appropriate question since the ICSE Grade System is quite different from the one followed by the CBSE or State Boards.

If you are an ICSE student sitting for the ICSE Class 10 Exam in 2026-27, a parent attempting to decode your child's marksheet, or a teacher helping the students with the result, this article covers every essential aspect related to ICSE Grades, how they are determined, their percentage range, and much more.

What is the ICSE Grading System?

The ICSE Grading System is the technique followed by the Council for the Indian School Certificate Examinations (CISCE) in evaluating a student's performance in the board examination of Class 10th. While in the case of pass or fail, there is no need for any evaluation or assessment, in the ICSE grading system, an objective means is provided to assess student performance and convey the same to the student.

A letter grade is awarded by CISCE to each subject that a student takes up in the ICSE examination based on the marks secured by the student in each subject.

The ICSE Grading System is applicable to all subjects offered in the ICSE examination and appears on the final marksheet of the ICSE examination conducted by CISCE.

ICSE Grades According to Percentage: The Complete Chart

The best way to comprehend the grading system of the ICSE exams in percentage terms would be the most effective way to start off. It should be observed here that the CISCE grades the students subject-wise. Each subject is graded individually, thereby allowing the student to score an A1 grade in Mathematics while having a B2 grade in History at the same time. There is no combined grade for the whole exam; the assessment of each subject takes place separately. The grading pattern is as follows:

Marks (Out of 100)

Letter Grade

Performance Description

91 – 100

A1

Outstanding

81 – 90 

A2

Excellent

71-80

B1

Very Good

61-70

B2

Good

51-60

C1

Average

41-50

C2

Satisfactory

33-40

D

Pass

Below 33

E

Fail / Needs Improvements

How ICSE Grades Are Calculated

The process behind arriving at your ICSE grades involves more than just the marks from written examinations. Here is how the full picture comes together:

  • Marks for Written Examination: The board examination of CISCE is awarded the maximum marks of 80 out of 100 for almost all the subjects. It is this part of the assessment that the candidates spend maximum time preparing for and is the main contributing factor towards their final grades.

  • Marks for Internal Assessment/Practical Exams: The marks for internal assessments or practical exams for the remaining 20 out of 100 marks are assessed by the candidate’s respective schools and then forwarded to CISCE. They are then added up to give the marks out of 100.

  • Derivation of Final Grade: Once the marks for each subject out of 100 are totalled, the final letter grade is assigned according to the grading system shown in the percentage range chart given above.

This combined approach ensures that the ICSE grading system reflects both a student's exam performance and their consistent academic engagement throughout the year.

Understanding Your ICSE Marksheet

The ICSE marksheet can look detailed and sometimes overwhelming at first glance. Here is what each section typically communicates:

  • Subject-wise Marks and Grades: All the subjects are enumerated here separately with marks scored and grades awarded. The electives chosen in Group II or Group III appear in the list as separate subjects, and compulsory subjects are also listed separately.

  • Best of Five Aggregate: CISCE uses the marks scored by students in their best of five subjects for the purposes of ranking and for making admission decisions. The best five subjects include English, without which no aggregate can be calculated.

  • Minimum Passing Requirement: If a student scores at least 33 marks (Grade D) in all the subjects, the student is termed as having passed the ICSE exam. Failure to score the said marks makes the student fail in that particular paper.

5 Tips to Improve Your ICSE Grades in 2026-27

If your current performance is not where you want it to be, the grading system itself gives you a clear target. Here is how to move up:

  1. Know your cut-off point. If your current score is at 58%, then all it takes is 3 extra marks to get into the B2 zone. Some targeted practice sessions in your weaker areas will take you there much more easily than you think.

  2. Consider internal assessments as important. Due to the 20 marks from your school's assessments, your entire academic year will count towards the board examinations.

  3. Pay attention to English. English is required for the purpose of the best of five in the calculation of your ICSE score. This means a good English score makes a huge contribution to your ICSE scores.

  4. Practice papers from last year. ICSE questions are designed in such a way as to test whether you understand the concepts thoroughly and can express your answer properly. Practising previous years' papers is perhaps one of the best strategies you can apply in order to increase your marks.

  5. Find help in weak subjects right away. Do not postpone getting help for your weak subjects until your final exam.
