Ever since I've learned about him in 8th grade, all my American history teachers stressed that he's a great president due to how much he expanded executive power. I asked my APUSH teacher about earlier this year and he said with confidence that Andrew Jackson was one of the top 10 presidents (he checks the CSpan rankings every year so I was sure he knew what he was talking about). Today I checked the CSpan rankings for presidents because I was curious where Obama was placed, and I found Andrew Jackson all the way down at 18th place. Have all my teachers been full of hot air? Is there a reason that he's so low this year?
in addition to my post see this post before the 2017 rankings came out featuring great comments by /u/Irishfafnir and /u/DBHT14

CSpan rankings every year
it's actually only redone every presidential transition.
Today I checked the CSpan rankings for presidents
This isn't really a "historical" point as much as an analysis of the C-Span rankings/a look at the data points in the C-Span ratings
https://www.c-span.org/presidentsurvey2017/?personid=39790
his "points"
2000: 631
2009: 605
2017: 609
Thus his point score actually increased from 2009 when he "ranked" 13th to 2017 when he ranked 18th.
These rankings aren't actually checking "significance" (though skowronek's conception of presidential time greatly complicates the basic notion that presidents are comparable to each other 'ceterus paribus' given political and growing institutional constraints).
the "real" question you want to ask is why over the last ~20 years Jackson has been subject to a negative re evaluation. Essentially the C-Span data isn't really evidence that Jackson has been subject to a negative re-evaluation over the last few years.
Given your post was a couple of days old and didn't get many bites I tried to reask the question here
