The survey, which is taken every four years by 170 of APSA's presidential experts, put Abraham Lincoln and George Washington at the top of the list.
"His average rating is 12.34, which is almost three points lower than [15th US President] James Buchanan (15.09), who previously occupied the lowest rank", the survey revealed. The scores were then averaged, the poll report said.
Abraham Lincoln was in first place, followed by George Washington in second and Franklin D Roosevelt in third. Those presidents' ranks remained unchanged from 2014.
Barack Obama is ranked 18th in 2014's survey, but after leaving office he rocketed into the top ten and is now considered the eighth greatest president, according to ASPA experts. Independent scholars, meanwhile, ranked Trump only ahead of Buchanan, whose presidency set the stage for the American Civil War.
Overall, Trump came last.
The president received three Fs and two Ds, scoring his highest grade in communicating with the public and his lowest on embodying institutional norms. Self-identifying Republicans scored Trump with three Ds and two Cs.
Trump was also rated below William Henry Harrison who died after only a month in office - from March 4, 1841 to April 4, 1841.
Trump did not fare well even when parsing the results by party and ideology.
The biggest declines were for Bill Clinton, arguably the result of contemporary scorn for his treatment of women, and Andrew Jackson, for evolving attitudes on his treatment of Native Americans.
"Donald Trump is by far the most polarising of the ranked presidents", poll authors Brandon Rottinghaus and Justin Vaughn wrote.
