NPR again left-center bias but  again "Very High for factual reporting due to thorough sourcing and very accurate news reporting."

The key is thorough sourcing and accurate reporting.

How does Fox fare?
To quote:"Overall, we rate Fox News strongly Right-Biased due to editorial positions and story selection that favors the right. We also rate them Mixed factually and borderline Questionable based on poor sourcing and the spreading of conspiracy theories that later must be retracted after being widely shared. Further, Fox News would be rated a Questionable source based on numerous failed fact checks by hosts and pundits, however straight news reporting is generally reliable, therefore we rate them Mixed for factual reporting."
