For last five years, we have been hearing about the government's interest in holding a common exam for admission to all engineering colleges. Recently, a news item said that the success of NEET is encouraging the Government to take a similar decision on a common engineering test for engineering.
First of all, one wonders what this success of NEET means. I am noticing so many legal challenges, so much stupidity in organizing NEET (different papers in different languages), and so many state governments unhappy since they see this as interference in their domain. They also have fears that NEET discourages against students following a state board, and hence indirectly forces a common syllabus across the country. But I guess success at the government level is to be measured more in political terms than in academic terms, and certainly, there is a perception among the people that giving less exams somehow helps them, and therefore, all politicians would want to reduce the number of exams.
There is a legal aspect to it too. The entire medical education in India is supposed to be supervised by Medical Council of India. The status of All India Council for Technical Education is not equivalent. Supreme Court has said that AICTE can not control universities, but only affiliated colleges, and hence AICTE has no say on IITs, NITs, IIITs, State universities, private universities, and so on. So what will be the legal process through which a common engineering exam will be introduced is not clear. (Of course, a dummy case in SC which demands common exam and which is not opposed by Govt/AICTE, etc. could be a simple way. Alternatively, a law can be passed by parliament. Or simply there is this method of arm twisting which is extremely effective in India - remember how everyone was told to get rid of 4-year undergraduate programs.)
But I am not a legal expert. I will only talk about academics.
Does a common exam help students? The perception, of course, is that it does. The naive argument is that every exam causes stress, and more the number of exams, higher the stress. People supporting this argument includes IIT directors and professors (but only if there are two exams, one for IITs and one for everyone else). The same people who inside IITs would sing praises for continuous evaluation and vote against just one big end-semester exam. There, the argument will be, that one exam puts all eggs in one basket and hence causes stress. We must have multiple evaluations with small stakes.
What is also very strange is that no body ever is happy with his/her performance in an exam. I get hundreds of emails from JEE (Adv) passed students every year, and all those mails will start from "I made a silly mistake or two, otherwise, I was expecting better performance." If students are unhappy with their performance in the big exam, shouldn't they be supporting multiple exams. Also, look at the number of students who drop a year because in that one big exam, they think they could have done better. What a huge waste of resource for the country. If they had multiple options and had received some alternate good education, many of them would not have dropped a year.
Stress happens not because of the exam, but the stakes associated with the exam. If I were to tell students that I am going to give an exam in an hour, but it has only 1% weight on the final grade, do they get stressed. Of course, not. Reduce the stakes, and you will reduce the stress. So multiple exams, each with lesser stake, is so much better for stress management than a single exam with huge stakes.
People who accept the logic so far will then argue, but having 100 different exams is still stressful even if each exam has less stress. And my answer is: How many students take 100 or even 10 different entrance exams. A few who may be taking 10 different exams, do they need to. Why are they taking 10 exams. Shouldn't they instead do some research about the kind of places that one wants to join and has the academic preparedness to get admitted to. 10 exams would open thousands of doors already. Frankly, we cannot reduce the number of exams because there is this person somewhere who refuses to do introspection, who refuses to do some research into various colleges and programs, and then insists on trying his/her luck with everything under the sun.
There is another problem with one exam. It is sorting you based on your preparedness in one dimension. People are not identical. If someone is really good at Physics and Maths, s/he will do better in an exam where Chemistry has less weight or is easier. Is it fair to banish this guy to a low rank for all educational institutions in the country. IITs may consider Chemistry to be important, but should every university be forced to consider Chemistry as important. What if you are good at languages. There is huge amount of research which shows that being good at a language increases your chances of success. Now, government institutions may be afraid to get into language politics of the country and not have language component in the entrance test, but should private universities also be forced to admit students without considering their language abilities. (India is the only nation in the world where admission to higher education is done without considering language abilities.)
If there is a single test, it really amounts to asking fish to climb a tree, and then saying that we were fair since we asked everyone to climb a tree.
From the university point of view, if I am offering only courses in Maths and Computing, I may argue that I want to admit students who knows maths and programming, and I am willing to teach them whatever little Physics they need to know, and I don't care about Chemistry. Should that not be the prerogative of the university to admit students based on different capabilities. I may even say that as a university, I want to admit students who are aware of their surroundings, and will have a general knowledge test for that. Should that be illegal. As a university, I may want to acknowledge different achievements of the student, including sports and give them some bonus marks. Should that not be allowed.
So a single test is taking away the most important component of the autonomy that a university must enjoy, and is being unfair to most students since most students' capabilities and interest would not align with any one particular test.
There is more to it. What should be the syllabus of this exam. If the syllabus is the intersection of syllabi of all boards, then it is going to be pretty less and may not be acceptable to most universities in the country. But if we add some topics other than the common part, then we are being partial. This is exactly the point of several states in case of NEET. By choosing one syllabus for NEET, you are discriminating against state boards whose syllabus is significantly different from that chosen syllabus. Same thing will now happen for engineering education, if a common exam is forced on this country. Having state level exams were allowing students to get admission to top colleges of their respective states without being forced to go through coaching of topics that they have not learned in schools. Now that option will be taken away.
I know many readers of my blog would argue that uniformity is a good thing, and let this common test force all state boards to change their syllabus to the CBSE syllabus. Many people just love uniformity, but they either want mediocrity or they do not know that uniformity can only lead to mediocrity or worse.
The suicides in Kota happen due to high stakes and thus high pressure from parents to succeed in JEE. If there is only one exam, brace yourself for a much higher pressure and many more suicides.
So a common test (like NEET) increases stress by increasing stakes, forces a linear ranking among students who have widely different skills and training and thus is unfair to most students, is unfair to students who have studied in state boards, takes away the most important component of autonomy of universities, bars any innovation in admission process by universities, and really gives us nothing in return of all these costs.
