We are a project of the Annenberg Public Policy Center at the University of Pennsylvania, as indicated on our About Us page: http://www.factcheck.org/about/our-mission/

FactCheck.org operates as an exclusive fact-checking site. It is a project of the Annenberg Public Policy Center at the University of Pennsylvania. It appears to me that it is a legally registered organization as it maintains copyrights and solicits donations, but, as I searched the FactCheck.org website, I could not find direct evidence that it is a legally registered organization. I did find evidence elsewhere. 

https://www.factcheck.org/archives/

FactCheck.org clearly meets this requirement. The site publishes fact-checks on a regular basis. The reports evaluate distinct claims on the basis of their accuracy.

We fact check the statements of major U.S. politicians, answer reader questions, debunk viral deceptions, and write Q&As on important public policy issues. Here are 10 links from 2019 that show the scope of our work:

FactCheck.org conducts fact-checks of claims made by Democrats, Republicans, and news organizations. It also fact-checks viral messages that fly through social media outlets, such as one claiming that Fox News was not airing the Mueller hearings on July 24. They were. There is not an undue concentration on "one side" of the politiacl aisle in the fact-checks I reviewed from January 1-July 25, 2019. Moreover, there is not a concentration of fact-checking one sideof the partisan and/or ideological aisle to "exonerate" them while fact-checking another side to "catch them" in a false statement.

We have a policy that staffers and students must sign that clearly states that they cannot be involved in any political or advocacy organizations, and they cannot make any contributions to such organizations.

In addition, we make clear on "Our Funding" page that we do not accept advertising or money from any person or organizations engaged in partisan politics. It says, in part, "We do not seek and have never accepted, directly or indirectly, any funds from unions, partisan organizations or advocacy groups. We do not accept funds from corporations with the exception of Facebook, which provides funding as part of Facebook’s initiative to debunk viral deceptions circulating on the social media site." https://www.factcheck.org/our-funding/

We also have a page on the website that describes "Our Process," which states that "we seek to devote an equal amount of time reviewing claims by Republicans and Democrats" and explain how we accomplish that. https://www.factcheck.org/our-process/

FactCheck.org requires their staffers and students to sign a document affirming they can't be involved in political advocacy. They do not accept money from political orgaizations that engage in partisan politics (both electioneering and governing). FactCheck.org does not engage in the taking of policy positions or advocacy on behalf of candidates.

We provide embedded links to our sources in all of our stories. In addition, we also list sources at the end of these stories: Featured Posts, Ask FactCheck, Ask SciCheck and Debunking False Stories. These links are used by our staff to fact check our stories before they are published. In cases when links are not publicly available, we will upload documents to our website -- if possible.All this allows our readers to replicate the fact check.

We also have a public policy -- "Our Process" -- that explains how we select our sources and why. We rely on primary sources of information, such as government records and data, and nonpartisan government agencies, such as the Congressional Budget Office and the Congressional Research Service. We also will use a few respected and trustworthy outside experts. The "Our Process" page can be found here: https://www.factcheck.org/our-process/

FactCheck.org links to all of the evidence they use when conducting fact-checks. The Our Process page describes the various inds of sources they use to check claims. They also provide a video on their Our Process page that provides additional descriptions of their sources for fact-checking. In the fact-checks I reviewed, the sources are clearly described. Sometimes, documents are uploaded to the site if a link was not available. It should be possible for a person to replicate the organization's process, given the clarity of the sourcing. The sources are of a high quality, usually relying on offical, publically available accounts of matters directly relevant to the claim being checked.

We publish quarterly financial reports on our website that explain in detail the types of funding that we do and do not accept: https://www.factcheck.org/our-funding/

We do not seek and have never accepted, directly or indirectly, any funds from unions, partisan organizations or advocacy groups. We do not accept funds from corporations with the exception of Facebook, as noted above, as part of Facebook’s initiative to debunk viral deceptions circulating on the social media site. We disclose the identity of any individual who makes a donation of $1,000 or more. We also disclose the total amount, average amount and number of individual donations. In 2015, Inside Philanthropy praised our disclosure policy for “exemplifying nonprofit transparency.”

FactCheck.org is a model of clarity and transparency with respect to funding. They clearly list the support they get from Annenberg, Facebook and all individual donors about $1,000. It isi easy to find, on the Our Funding page. However, the organization does not set out an overview of spending.

We provide bios of our current and past staff members here: https://www.factcheck.org/our-staff/

We also provide a list of our current student fellows here: https://www.factcheck.org/undergraduate-fellows/

FactCheck.org lists biographies for all staff members, including those who conduct fact-checks. They are very easy to find on the webiste. In fact, the site lists past staffers as well - a model of transparency and clarity. The site also lists the names of the student fellows who work on the site, but the biographical information about them is relatively skimpy.

At the top of our homepage, we added a drop down menu called "ASK A QUESTION," which provides links for readers who want to submit questions for Ask SciCheck and Ask FactCheck.

The links:

https://www.factcheck.org/askfactcheck/

https://www.factcheck.org/askscicheck/

At the top of our homepage, the "About Us" drop down menu includes a link on how to contact us: https://www.factcheck.org/about/contact-us/

The "Contact Us" link also appears at the bottom of every page. 

It is easy for readers to reach out directly and request a correction or suggest a fact-check on a particular claim. Anyone moderately familiar with internet use would be able to find the portals to reach out to the organization.

https://www.factcheck.org/askfactcheck/ is one option.

Another, at the top of the homepage, is the "About Us" drop down menu includes a link on how to contact them: https://www.factcheck.org/about/contact-us/

"Our Process" page details the methodology we use to select, research, write, edit and, if necessary, correct or update our articles: https://www.factcheck.org/our-process/

The "Our Process" page also includes links to videos that we produced for International FactChecking Day last year that explain our process in more detail.

Those videos and others can also be found here: https://www.factcheck.org/2018/04/its-international-fact-checking-day/

FactCheck.org has a clear method for conducting fact-checks. It is clearly labeled and easy to find for members of their audience. The corpus from which they select their claims includes Sunday morning political talk shows, C-SPAN, campaign advertisements, congressional transcripts, presidential statements, campaign and official websites and reader inquiries. Once a claim is selected, it is carefully and transparently reported. After a significant editing process, fact-checks are published. Notably, they come without a "rating" (i.e. true, false, half-true). Fact-checks are treated holistically. 

At the top of our homepage, we added a drop down menu last year called "ASK A QUESTION," which provides links for readers who want to submit questions for our features Ask SciCheck and Ask FactCheck.

The links:

https://www.factcheck.org/askfactcheck/

https://www.factcheck.org/askscicheck/

FactCheck.org clearly explains their process, but they do not make explicitly clear what is and is not a checkable claim. The site has several links and a video that explains their process and clearly explains what will be published as a fact-check. For instance, they note that if a claim checks out (i.e. they contact the claimant and the claimant satisifed FactCheck.org), they drop the matter. In my own view, checking claims that turn out to be true is a valuable service and should not be abandoned (but that is not related to the compliance criteria). The video does a better job of describing what can the audience can expect to be checkable, but that is a bit less accessible. I could not find evidence that the organizations gives statistics on the frequency of reader suggestions ending up as published fact-checks. They do provide a very easy-to-find and understand page that describes the most frequently suggested checks they receive.

Our corrections policy can now be found in two places on our home page.

As in past years, our corrections policy can be found in the "Our Process" page.

However, at the request of a reader, we created a separate page and link to our correction policy to make it easier for readers to request corrections. We added it to the "About Us" drop down menu at the top of the home page. It says "Request a Correction," and links to this page: https://www.factcheck.org/request-a-correction/

It is easy to request a correction of the organization. They note, "If any new information comes to light after we publish a story that materially changes that story, we will clarify, correct or update our story and provide a note to readers that explains the change, why it was made and the date it was made. Readers can contact us at editor@factcheck.org to request a correction or clarification.

Our goal, as stated in our mission, is to apply the best practices of both journalism and scholarship, and to serve as a nonpartisan, nonprofit “consumer advocate” for voters, regardless of their party affiliation.

We treat conservatives and liberals alike and apply exactly the same standards of accuracy to claims made by both sides."

They do not provide an estimate of the timeframe it will take to determine if a correction is warranted.

A reader pointed out a mistake in our story on GDP growth in 2018. We corrected our mistake and thanked our reader: https://www.factcheck.org/2019/03/spinning-gdp/

In this story, we used outdated CBO data on the impact of repealing the individual mandate on the number of uninsured. We corrected the story to include the latest data: https://www.factcheck.org/2019/02/factchecking-sanders-cnn-town-hall/

FactCheck.org clearly and swiftly corrects known errors. They make readers aware of this in two ways. Under the byline, they list a publication date and a corrected on date for stories that needed correction. Additionally, they provide an italicized description of the correction at the end of the story. They do not have an easy to find location chronicling all corrections, which would provide even more transparency for the audience.
