Slide 20. USPSTF Letter Grades

Presentation describes the methods used by the US Preventive Services Task Force to develop recommendations.

USPSTF Letter Grades

Text Description is below the image.

  • The recommendation is linked to a letter grade that reflects the magnitude of net benefit and the strength of the evidence supporting the provision of the specific preventive service. The recommendation is graded from "A" (strongly recommended) to "D" (recommended against). When the evidence is insufficient to determine net benefit, the Task Force assigns a grade of "I."


Both the benefit of the proposed intervention, and potential problems that could occur are taken into consideration before a recommendation is made.
