FAA Type Rating is done to ATP standards. Therefore you can get a type rating on even a PPL. Once you upgrade your airman certificate to CPL or ATP the type rating transfers to that certificate. But obviously entry requirements for someone with only a PPL and seeking a jet type rating will be different. I am talking about a PIC Type Rating and not the SIC type rating which essentially is an administrative type rating given to meet ICAO requirements for international flying. The SIC type rating does not even require a check-ride.
