Given the changes to the guidance and questions, can PART scores and ratings be compared from one year to the next?
While some changes have been made to improve the consistency and accuracy of the PART ratings, they are not significant enough to prevent comparisons between years or show changes over time. The guidance and a few PART questions changed from 2004 to 2005. For the 2006 PART, the questions remained the same as 2005, but changes were made to the PART guidance.
