Public service loan forgiveness

Hi Terry! My husband is a physician and has quite a bit of medical school loan debt. He is eight years out of school and has worked for non-for profit hospitals since graduating. He is currently looking for another job and is interested in a for-profit hospital. We are hoping to be eligible for the public service loan forgiveness program (that is, of course, if it is still in existence) in two more years. I am aware we need 120 income based loan repayments, but I am unsure if this needs to be consecutive or not. We have continued to pay our loan payments throughout Covid although they are not required, in order to reach the 120 payments more quickly. Are you familiar with this program? Can you give us any guidance? Thank you so much!
