The star rating is a representation of the overall rating, calculated as the mean of the client satisfaction rating, interview rating, and internal vetting rating.
Client satisfaction rating is the weighted average of client ratings, with weights based on reviewed work hours. When no client rating exists, the approval fraction (approved vs. reviewed work hours) determines it.
If the client satisfaction rating exceeds the overall rating, it becomes the star rating. In the absence of client ratings, if the average interview rating is higher than the overall rating, it becomes the star rating. If no data is available, the star rating defaults to the internal vetting rating.
