Yes. The amount depends on the amount of money the person made during her/his tenure in CES, and length of time spent working. (includes all the BYUs: Provo, Idaho, Hawaii, etc.)
I left CES after 27 years, at age 52, and will receive a partial pension.
There is also a retirement savings program.
Added to SS, it ought to provide a comfortable income after retirement.
Problems occur when investments in the retirement savings program tank. But everyone deals with that unless they get lucky.
