No, I don't think things are as easy as changing the head of state.
Hahaha, you think its just a head of state change.
First of all he is not the head of state. (And yes changing the actual Indian head of state would have no effect at all on anything).
2nd you have little to no idea about how the politics work in India at all regarding its democracy (and what levels exist of it)...and no I don't have the time or inclination to educate you. The report is for those that want a summary and actually want to ask specific details in which case a conversation may be had....rather than "oh its authored by Indians...and is a "consultancy" based rigmarole....and therefore cannot be valid".
so tell me how many 5th graders can read like a normal 5th grader,
Do you know if the previous govt has even referenced contemporary ASER findings and specifically put an action plan to address the problem? Do you know what this govt has done in comparison? I bet you don't.
Also have you looked at whether the situation is homogeneous one or if there are states where there has been drastic improvement (which others are now looking at implementing with regards to teacher training and standards verification)? I bet you haven't.
Instead you take probably one article you came across and probably had one number stick in your head and decide oh well thats the stagnant situation everywhere. I take a different approach, I look at the reports in detail with a fine tooth comb to gather a better picture. The results even under the previous administration, as bad as it was, contain some very interesting pieces of information state wise (because again you fail to realise what the balance of power is between centre and state in India given you think the PM is a head of state). The same data is not even out yet for this current administration to judge them on....but I can certainly see a trend from the publications they have released and much greater interaction they have promoted with local socioeconomic groups and local NGOs.
So is it worth taking the time to convince you otherwise? Nope.
I for one will be watching the ASER reports that come out in the next couple years (they havent even released the one for 2015)....because I know what the time lag is for education reform but I also know its not stuck in a rut like before....and there is evidence in a lot of data out there to illustrate that.
But you are free to believe what you want.
