Level 7 Chartered Member

Hi, I was hoping to get some advise around Level 7 Chartered Member Qualification. I have a level 5 Associate member currently working as an Employment Relations Manager, I am very much interested in obtaining my Level 7 CIPD to become a chartered member and would like to know if the process is the same as getting a Level 5. Do I need to go for classes and get an assessment through written assignment? How long will it take to get a level 7 and what is the cost? Thanks
