Gallup has reported on presidential job approval since 1938, and for the vast majority of that history (1938-2008), this reporting was based on reporting job approval ratings from discrete, multiday surveys.
From 2009-2017, Gallup measured presidential approval using daily sampling and interviewing on its tracking survey, reporting the results as three-day rolling averages.
In 2018, Gallup measured presidential job approval using weekly sampling and interviewing on its tracking survey, reporting the results as weekly averages. The 2017 three-day rolling averages were replaced in the trend by 2017 weekly averages to maintain consistency in reporting on Donald Trump's presidency.
In 2019, Gallup is returning to its 1938-2008 practice of reporting job approval ratings from its discrete, multiday surveys.
Gallup's latest presidential approval rating will continue to be found on News.Gallup.com in the following locations:

Insights about the dynamics of presidential job approval, gleaned from Gallup's more than 80-year trend, are available in "Trump Approval More Stable Than Approval for Prior Presidents."
Until 1989, Gallup conducted interviews using face-to-face interviews.
Since 1989, Gallup has conducted all of its polls by telephone.
In 2008, Gallup's national Random Digit Dialing (RDD) telephone samples included cellphone interviews for the first time, with most interviews still conducted on landline telephones. The proportion of cellphone interviews has since steadily increased.
