JEE Main 2019 will be conducted by National Testing Agency and the results shall be announced on January 31, 2019. The coming year will see some major changes in the format of JEE Main 2019 precisely due to introduction of two attempts for the same year and reintroduction of normalization process.
The merit list for JEE Main 2019 for both the papers will be prepared jointly. The candidates appearing for the second attempt will have a separate merit list. But to determine the final AIR, NTA would take the best of both the attempts.
The information bulletin issued on the official website of JEE Main states the purpose and procedure of normalization procedure. Prior to this the former JEE Main conducting body, Central Board of Secondary Education (CBSE), had introduced normalization procedure to equate class 12th examination in order to bring different state boards at par with each.
The procedure was called off as board examination marks couldn’t be put to proper use to realize All India Rankings. In the year 2019, NTA will do normalization but for a very different purpose i.e. to normalize the difficulty level of exams to be conducted in different shifts.
The information bulletin on Normalization procedure states, “In spite of all efforts of maintaining equivalence among various question papers, the difficulty level of these question papers administered in different sessions may not be exactly the same. Some of the candidates may end up attempting a relatively tougher set of questions when compared to other sets”.
Consequently, candidates attempting tougher paper are likely to get lower marks in comparison to those attempting easier paper. The remedy to which is normalization procedure based on percentile score. This will ensure that the candidates appearing in the examination should neither benefit nor loose due to the difficulty level of the entrance.
What is Normalization Procedure
Normalization procedure as we all know is nothing new and many national level testing agencies have been following the practice to overcome disparity occurring in multiple testing formats. It compares candidates’ scores through established methods across multiple sessions to formulate a final merit list. NTA will be using percentile equivalence method for the same.
Before we delve further on step by step procedure, for students and other readers it would be difficult to understand normalization procedure until they don’t understand basic terminologies like –
Percentile Scores: The scores based on the relative performance of number of candidates appearing for the exam are the Percentile Scores. The marks (raw scores) obtained by the candidates are brought down to a scale ranging from 100 to 0 for each session of test takers. In other words a Percentile Score is the percentage of candidates scoring equal to or below (raw scores) the particular percentile for that examination.
Latest News Updates
Raw Score: Original marks of a candidate which he or she has obtained based on the marking scheme. In JEE Main for each correct answer there are 4 marks and for each incorrect answer there will be negative marking by 1 mark.
Subject Percentile Score: This is again percentile score but for the given subjects. In JEE Main this would calculated separately for each subject – Mathematics, Chemistry and Physics.
Merit List: The merit list will determine the All Indian Ranking of candidates on the basis of best of both the attempts and normalization procedure.
NTA will use predefined formula for determining overall and subject wise percentile scores.
Step by Step JEE Main Normalization Procedure Exaplanation
Step-1: Distribution of Examinees
The distribution of examinees for different shifts in a day would be done to have approximately equal number of candidates for each shift. In case there are more numbers of days or number of shifts then examinees would be divided accordingly.
This is to overcome any bias that may arise due to distribution of candidates appearing in the examination. Further, with over Lacs of candidates taking examination from different parts of the country the possibility of such biasness would be zeroed down.
Step-2: Preparation of Results
The results for each session shall be prepared in the form of Raw Scores and Percentiles Scores. NTA will also prepare scores separately for each subject and the Total.
Step-3: Score Compilation and Preparation of AIR
The percentile scores as obtained from Step 2 shall be finally considered as NTA scores based on which results would be compiled to announce AIR. Based on theses ranking candidates will qualify for JEE Advanced and admissions to IITs, IIITs and GFTIs.
Tie Breaking Process in JEE Main 2019
The JEE Main 2019 also states clearly the procedure to break down ties between candidates. It will be done by taking the following parameters into consideration (listed in the order of preference):
· The Percentile Scores will be calculated up to 7 decimal places.
· Higher percentile in Mathematics
· Higher percentile in Physics
· Higher percentile in Chemistry
· Lastly, to the candidate who is elder in age.
It looks all positive right now and students can feel relieved because of the format changes about to take place in JEE Main 2019. Moreover, two attempts is a welcome change in format which shall reduce the dropout numbers.
