Hello Aspirant,



No, it isn't necessary to do B.El.Ed to become a lecturer, you can pursue any Bachelors degree ,then masters degree and then you will have to clear entrance exam like UGC NET or any other equivalent exam and sude by side you can pursue Ph.D or M.Phil.


After B.El.Ed you can go for school teaching or you can do bachelors degree or masters degree in any discipline then pursue B.Ed .
