Last month, the JEE (Advanced) conducting authorities
released a set of data reports on the final results of the JEE (Advanced) and
its previous avatars, from 2011 onwards. In this set of analysis of these
reports, we will discuss individual elements of the reports and how they are
shaping up for you.

In Part 5, we discuss the number of students who qualified
for Allocation to the IITs after clearing the entrance exam and other
eligibility criteria.

Till 2012, the JEE was conducted independently, and was known
as IIT-JEE. The exam for NITs and other institutes, the AIEEE, was conducted
separately. Since 2013, the two-tier JEE (Main) + JEE (Advanced) was introduced
for all institutes. Till 2014, allocation of seats used to be independent of
NITs and other institutes. In 2015, the Joint Seat Allocation Authority (JoSAA)
was introduced, when seats were allocated together in all institutes.

In 2011 & 2012, about 5% of the total students who gave IIT-JEE were considered qualified for allocation of seats – about 2.5 – 2.7 aspirants per seat.

Since 2013, with the introduction of the two-tier JEE, the number of students who appear for the final entrance exam to be considered qualified for allotment has dropped to 1/4th of the time when the exams were separate. Due to this, the percentage of students who would be considered qualified for the exam has increased four-fold, while the absolute numbers have remained nearly the same. For example, in 2015, 22.5% of those who appeared for the JEE (Advanced) qualified for allocation, whereas the number of students per seat was still 2.6 – quite close to the IIT-JEE era ratio.

In fact, except for 2013, where an extremely low number of
students qualified for allocation (18% of those who appeared), the other ratios
have remained pretty stable throughout the 3 eras – IIT-JEE, JEE (Advanced)
+ separate allocation, and JEE (Advanced) + JoSAA.

As can be seen, the seat allocation authorities have tried
to maintain a standard 2.5-2.75 aspirants per available seat ratio, and hence
have been able to keep vacant seat counts low. Over the coming years, more
changes are expected in the JEE structure, and we shall keep track of how these
changes are affecting the students’ chances of getting into an IIT.
