Note: Detailed information about enrollment, eligibility criteria, timetable, and enrollment fee will be announced soon.

The full form of INPhO is Indian National Physics Olympiad is the second stage of the five-stage Olympiad program for Physics in India. It ultimately leads to the selection of the International Physics Olympiad. The INPhO Exam is conducted on the last Sunday of January (or on the first Sunday of February), every year, by the Homi Bhabha Centre for Science Education. Students in school(usually the students of standards 11 and 12l) first need to qualify the National Standard Examination in Physics (NSEP) held on the last (or second last) Sunday of November of the preceding year. Among over 40,000 students that appear for the INPhO examination at almost 1400 centres all across India, around 300 to 400 students are selected for INPhO based on their scores and also based on regional quotas for the states from which the students appear. Different state-wise cut-offs exist for selection to INPhO. INPhO Exam serves as a means to select the students for OCSC (Orientation Cum Selection Camp) in the subject Physics, as well as to represent India in the Asian Physics Olympiad (APhO).

Most of the students qualifying the INPhO are those that are completing their twelfth standard. However, there have been some instances of students who have qualified INPhO at the end of the eleventh and very rarely, in the tenth standard itself.

Conducted by: Indian Association of Physics Teachers

First Conducted: 1987

Stages of INPhO

The Physics Olympiad program has the following fives stages-

(Image to be added soon)

  • Stage I: NSEP- The full form of NSEP is National Standard Examination in Physics 

  • Stage II: INPhO- The full form of INPhO is Indian National Physics Olympiad 

  • Stage III: OCSC- The full form of OCSC is Orientation cum Selection Camp in physics

  • Stage IV: PDT- The full form of PDT is Pre-departure Training Camp for IPhO

  • Stage V: IPhO- The full form of IPhO is - Participation in International Physics Olympiad 

Stage I, which is the National Standard Examination is entirely the responsibility of the Indian Association of Physics Teachers. All the remaining stages are organized by HBCSE. It is essential to qualify the NSEP Exam so as to participate in the INPhO.

InPhO 2021-22: Examination Pattern

The new examination structure will combine the first two stages of InPhO/IOQA into a single stage called the Indian National Olympiad (IOQA).

IAPT has stated that for each exam there will be a single examination comprising two parts that will be held in a single sitting.


This part will be known as NSE (National Standard examination)

Duration: 75 minutes

Question Type: Objective-type questions to be answered on an OMR sheet


This part will be known as INO (Indian National Olympiad)

Duration: 120

Question Type: Students are asked to write a detailed answer on an answer booklet. 

Note: The students will be writing both parts IOQA Part-I (NSE) & Part-II (INO) but the answer booklet of Part-II will be evaluated only if you’ve qualified Part-I. Also, the detailed criteria for qualification will be updated soon.

Procedure of Selection 

The procedure for the selection of students in Physics Stage II i.e., INPhO 2021 are: 

  1. The students are divided into two groups i.e. Group- A and Group- B. the students in Group A must be in class XII while the students in Group B must be in class XI or lower. 

  2. A separate Merit Index (MI) and Minimum Admissible Score (MAS) will be calculated for the two groups.

  3. The question paper of NSEP 2020 and INPhO 2021 will remain the same for two groups.

  4. A total number of 250 students from each group will be shortlisted for stage II of INPhO and therefore a total of 500 students will be selected.

3. What is INPhO?

The International Physics Olympiad (IPhO) is an annual event, which is held in the month of June – July every year. The country of the venue of the IPhO Exam varies from year to year. This activity has been conducted regularly for the past thirty-seven years. However, our country India began to participate in the IPhO Exam only in 1998.

The IPhO Exam is a keenly contested examination in physics open to pre-university students of all countries in the world. It serves as a benchmark for the study of physics at the pre-university level. It also fosters friendly relations among students from different countries.

It is believed that India’s participation in the IPhO Exam helps to boost the level of science education in the country. The physics olympiad programme in India, it aims to promote excellence in the subject physics at the pre-university stage and to select and train participants for the IPhO.

4. What is the Last Stage of the INPhO Exam?


Typically, the marks of several students are calculated by adding 40% of the marks scored in the NSEP Exam, as a percentage of the maximal marks attainable in the examination (generally 240) to 60% of the score in the INPhO Exam, as a percentage of the maximal marks attainable (varies from year to year). A list of the top 50 students is prepared, and the top 8, who are willing to appear for APhO, are selected.
