My agency https://www.upwork.com/agencies/~01430e1381791f8ff6 JSS dropped for more than 20% in a last 2-3 weeks. Why it is happening? All last projects was closed with more than 4 stars rating
There are many factors that go into your JSS calculation including public and private feedback given when the contract is closed, a pattern of contracts without feedback, etc. To learn more details about your Job success score and why it has changed check out this Help Article.
I've reviewed this article before my initial post. It doesn't help at all.
Last 3 projects within 2 weeks was closed with 5 stars feedback but JSS continiously dropping.
How to define what affects JSS in a such way.
Unfortunately we can't share more details about your agency JSS. Please refer to the guide Bojan shared in his post to learn more about the factors included in your JSS. Thank you.
