Grading and Evaluation System

For the Coursework, the system of Continuous Evaluation is followed in TIFR— thus students are expected to keep up with teaching at all stages and there is no study leave before examinations.


Continuous Evaluation of every Compulsory course is generally based on (a) a Mid-semester examination, (b) an End-semester examination, (c) classroom and/or take-home assignments, and (d) any other criterion set up by the Instructor of the course.


For all courses, irrespective of Credits, every student is assigned a mark out of 100. The qualitative estimation corresponding to the marks is give below:





















A student who fails a Compulsory course has to repeat it when it is next offered; if he/she passes the course, the new marks replace the old (failed) marks on the student’s transcript.


A student who fails an Elective course may repeat it or replace it by a different Elective, in consultation with the Department SBP representative and/or the Course Coordinator.


If, for some valid reason e.g. health issues, a student is unable to complete a course, an ‘incomplete’ (I) grade will be awarded. Such a course will not be included in the CPI calculation (see below) and will not be treated as a ‘failed’ course. However, the clearance process will be the same as for a ‘failed’ course.


A student may acquire a maximum of 3 ‘Incomplete’ grades during the entire coursework. Beyond this, all incomplete courses will be treated as ‘failed’ courses.  



The marks secured by a student in all the completed courses taken up to a certain point in time are used to calculate a Cumulative Point Index (CPI) as follows:

where  is the marks secured in a course with Credits  and both sums run over all the courses taken till the date concerned.

This CPI is the major criterion in determining the performance of a student in the Course Work.

For students in the Integrated  M.Sc.-Ph.D. programme, the M.Sc. degree awarded will have a Class attached to it according to the following CPI ranges:




First Class with Distinction




First Class




Second Class

For this purpose, all fractional CPIs will be rounded off to the nearest integer.

Inadequate performance

If the CPI of a student falls below 55, he/she will be placed on Academic Probation and will remain so until the CPI becomes 55 or more, or the Course Work ends. Likewise if a student fails (marks < 50) in one course, he/she will be placed on Academic Probation and will remain so until the course is cleared. A student on Academic Probation may be permitted to take one course less during the semester, in consultation with the Course Coordinator.

All CPI-related decisions will be taken only at the end of the relevant semester, taking the student’s current record into account.

Additional Department-specific criteria for performance may be found here.



The academic programme of a student will be terminated if

    he/she fails in more than two courses, irrespective of CPI.

    he/she fails in two courses and has CPI of other courses less than 65.

    he/she fails in one course while on Academic Probation.

    he/she fails to Register for Ph.D. by the end of the Second Year (for Ph.D. students) or Third Year (for Integrated Ph.D. students).

This dateline will be extended by any time lost due to leave granted by the Subject Board for medical or other reasons. It may also be extended if the student has to clear courses with ‘I’ grades.

    termination is recommended by his/her Department with sufficient reason(s) and approved by the SBP.

    termination on disciplinary grounds is recommended by a competent authority.
