Grading System (A1–E)
The CBSE grading system maps a student’s percentage to a nine-point scale: A1 (91–100), A2 (81–90), B1 (71–80), B2 (61–70), C1 (51–60), C2 (41–50), D (33–40) and E (below 33). Each grade band carries a grade point used to compute CGPA. This absolute grading reduces the pressure of small mark differences between students.
CBSE’s nine-point absolute grading scale from A1 (91–100%) down to E, replacing raw marks with grade bands.
Why it matters
Two different things are called the CBSE grading system, and confusing them costs the exam cell an afternoon of angry phone calls every results day. The absolute percentage bands schools print on internal report cards are not how CBSE awards grades on a board mark sheet — the Board uses relative grading against the candidates who passed that subject.
In practice
- For Class X and XII board examinations CBSE places all passed candidates in a subject in rank order and divides them into eight equal groups, A-1 down to D-2.
- Grade E on a CBSE mark sheet denotes Essential Repeat, not a low passing band — read it as a status, not a score.
- Because grades are computed per subject against that subject's passed candidates, identical marks in two subjects can carry different grades on the same mark sheet.
- Relative grading is applied where more than 500 candidates passed the subject; for smaller subjects CBSE follows the grading pattern of similar subjects.
- The familiar absolute bands (A1 = 91-100 and so on) are a school-level convention used on internally issued report cards; say so on the report card itself.
Common mistakes
- Printing board-style grade letters on school report cards without stating that the school's bands are absolute, not CBSE's relative grades.
- Promising a parent a likely board grade from marks alone — relative grades are not predictable before the cohort is ranked.
Common questions
Does CBSE's A1 grade mean 91-100%?
Not on a board mark sheet. For Class X and XII examinations CBSE uses relative grading: all candidates who passed a subject are ranked and split into eight equal groups, so A-1 is the top one-eighth of passed candidates in that subject. The cut-off in marks therefore shifts by subject and by year.
Why did my child get different grades in two subjects with the same marks?
Because each subject is graded against its own pool of passed candidates. CBSE states directly that under relative grading a candidate obtaining identical marks in two subjects may not receive the same grade, since the number of candidates passing and their score distribution differ between subjects.
Does CBSE award an overall division, distinction or percentage?
No. CBSE has notified that no overall division, distinction or aggregate is awarded, and that the Board does not calculate, declare or communicate a percentage of marks. Where a percentage or a best-of-five figure is needed, the admitting institution or employer works it out itself.
Edutris maps marks to CBSE grade bands automatically and computes grade points, so report cards are graded consistently instead of by hand each term.
