International Olympiad in Astronomy & Astrophysics

The International Olympiad on Astronomy and Astrophysics (IOAA) is an annual astronomy competition for high school students. It is one of the international science olympiads.
The Olympiad was founded from adissidence inside the International Astronomy Olympiad, in order to increase the scope of the organization.

The IOAA states that:-

“IOAA is designed to be a truly international organization on Astronomy and Astrophysics competitions. The organization is run by an international committee, whose members are elected from international members of the organization.”

THE IOAA EXAM IS OF 5 – STAGES:-

ASQURE-3-5-2019

stage:-1 (NSEA)NATIONAL STANDARD EXAMINATION IN ASTRONOMY,

NSEA – 2017

A Detailed Analysis by ASQUARE

Introduction:-

  • NSEA (National Standard Examination in Astronomy) –exam was conducted by the Indian Association of Physics.
  • Teachers (IAPT) at many centers all over the country. NSEA is the stepping stage for selection of aspiring and talented students in the astronomy Olympiad Program. The student can move forward to other stages only after clearing this stage.

Eligibility:

  • Only Indian citizens born on or after January 1, 1997 and are students studying in Class XII  can apply and appear for NSEA. The student has to himself re-assure his eligibility.
  • At any stage if the student is found to be not eligible for the exam, he/she may be disqualified from the program.

Syllabus: 

  • The syllabus for National Standard Examination in Astronomy (NSEA) is almost similar as the curriculum of senior secondary level (Class XI and Class XII) of CBSE.
  • However, only basic guideline for the course is mentioned. No detailed syllabus is given for NSEA. There is greater emphasis on physics and mathematics (calculus not asked) and elementary astronomy.

Qualifying for the Second Stage:

  • The basic objective of conducting this test is not focusing on merit but to involve as many students from the country to participate in the exam and try to show and expose their talent.
  • Hence the selection to the stage II examinations i.e. Indian National Olympiad Examinations (INOs) is based on the following scheme.

Cutoff: 

  • To be eligible to get to the next level, i.e. the second stage, it is necessary that a student scores at-least a Minimum Admissible Score (MAS) which is 40% of the maximum score.

Proportional Representation Clause: 

  • The maximum number of students that can get to Stage II (INO) in each subject is around 300. These many students are not selected only on the merit basis but also on proportionate basis.
  • This proportion is decided on the base of the number of candidates who appeared for NSE in the previous year from that center in each State or Union Territory (UT). In case there is a tie at the last position, then all the students competing for the last position will be eligible to move to stage II.
  • However it’s necessary that the selected students fulfill the eligibility clause laid out above. The total number to be selected from centers in each.

Minimum Representation Clause:

Notwithstanding the proportional representation clause the number of students selected for INO from each State and UT must be at least one, provided that the eligibility clause is satisfied.

Merit Clause:

  • Approximately 300 students are to be selected for second stage. If this does not happen according to MAS, then after selection as per merit, the shortfall from 300 students will be selected based purely on merit without further consideration to proportional representation and minimum representation clauses.
  • In the event of a tie at the last position in the list all students with the same marks at this position will qualify to appear for the Stage II examination.

There will be no other criterion or provision for selection to the Indian National Olympiad Examinations (INOs). All students who qualify to appear for the INAO get a certificate of merit from IAPT.

Overall Marks Distribution

The paper pattern was same as last year. The paper had 80 questions each worth 3 marks. All questions were objective type with single correct option each carrying -1 negative mark for incorrect attempt.

The subject wise breakup is as follows:

SUBJECT Class 11 Class 12 Total
No of Qs Total Marks No of Qs Total Marks No of Qs Total Marks Total

 Expected Cutoff:-

To be eligible to get to the next level, i.e. the second stage, it is necessary that a student scores at-least a Minimum Admissible Score (MAS) which is 40% of the maximum score.

STAGE:-2

Indian National Astronomy Olympiad (INAO)

INAO test is conducted by HBCSE at approximate 15 centres in the country.

Eligibility:

  • The eligibility criteria for participating in the INAO exam are: Students who are chosen from Stage I examination (NSEA) Students who have been exempted as described in the Enrollment page These are the two ways by which students can apply for the test.
  • The test is usually conducted in the month of February every year. The final date and timings are displayed in the first week of January on the website.
  • It is also conveyed to students by post who have applied through the post. Students appearing for INAO are eligible for TA/DA as per norms of the programme.

Syllabus:

  • The syllabus for INAO is almost same as that for NSEA. The syllabus is only a tentative curriculum guideline.
  • The Questions and problems to be attempted in National Olympiads are usually non-conventional and of high difficulty level, comparable to International Olympiads. Only 35 students will be choosen for OCSC Astronomy.

If there is tie at the last position, all students with the same marks at the last position will qualify for OCSC at the respective level. The student cannot get to this level by any other way.

STAGE:-3

Orientation Cum Selection Camp (OCSC) in Astronomy OCSC in astronomy is organized by HBCSE every year tentatively in April or May  for couple of weeks.

The final dates and schedule is announced either before or with the display of the selection list for the OCSC.

Eligibility for OCSC

  • Students who have cleared Stage II (INAO) are only eligible for the camp. There is no other way through which you can get into the camp.
  • The camps involve thorough understanding of topics through theoretical as well as practical i.e. Experimental tests and lectures.
  • At the beginning of the function, orientation is provided to students while the programme ends with a valedictory function where distinguished scientists are invited to speak to the students.
  • The students are ranked on the basis of the total scores achieved in all the tests in the camp.
  • For this ranking, 50% weightage is given to theoretical tests, 30% weightage is given to data analysis test while 20% weightage is given to the observational tests.
  • Performance in previous stages (NSEA and INAO) are not considered for the preparation of the merit list and awards of the OCSC astronomy.
  • The top 5 in the OCSC astronomy merit list will be special merit awardees and will be members of the Indian team for IOAA.
  • All the selected students will become part of the Indian teams only if they satisfy the eligibility criteria of age, Class, holding valid Indian passport, medical fitness, parental consent, etc.
  • Apart from selection to the Indian teams, the selected students will be awarded with a special merit award of Rs. 5, 000 each in the form of books and cash.

Stage IV:

Pre-departure Training (PDT)

Camps for IOAA The selected Indian teams for IOAA will undergo a rigorous training programme at HBCSE in theory, data analysis and observational astronomy.

Trained personnels and eminent personalities will be faculties to train the team of students. The duration of training will be subject to IOAA regulations.

Stage V:

IOAA

Participation in IOAA the 2 leaders and 1 observer (if any) for IOAA will accompany the Indian team.
