Hi Aminul Islam,
To earn Top Rated status, you'll need to maintain a Job Success Score (JSS) of at least 90% for at least 13 of the last 16 weeks. To add eligible weeks you need to get your JSS above 90% and keep it there long enough for the ineligible weeks to start falling out of the 16-week window. You have to look at the eligibility weeks as a rolling 16-week window. Please check the graph included in this help article and refer to the information shared in the Calculating Top Rated Eligible Weeks section.
