Four Year B.El.Ed. or Two Year Diploma? Which is better for CTET?

As published in The Times of India, New Delhi, Friday, April 8, 2011, page number 19, two major either qualifications for CTET are Four Year B.El.Ed. or Two Year Diploma in Elementary Education/ Education.
It means, one should be either B.El.Ed. (a four year course) or Diploma in El.Ed./Education (a two year course) to be eligible to appear in CTET.
While B.El.Ed. costs FOUR precious years of a Science Student to be an elementary teacher, the Diploma in El.Education/Education provides the same eligibility just in TWO years. Moreover, most of the Universities do not count B.El.Ed. as a minimum qualifying degree to enrol in M.Sc. courses. They have clear stand that it may be a Bachelor degree in Elementary Education, but not Sciences. And, of course, they, all, seems to be absolutely correct.
So, it can be inferenced that for CTET, one should pursue Two Year Diploma from DIET instead of Four Year B.El.Ed., if not contradicted.
What happens to B.El.Ed. holders, after the course, if they do not want to become elementary teacher, We will discuss later with the help of some Real cases from the field......
Tab tak ke liye, Namaskar.....
