Just note that Partridge Family aired on Nick@Nite, according to wiki, it aired 1993-1994, and July 1995.

Referring this from http://sitcomsonline.com/boards/showthread.php?t=336260 there's complete Nick@Nite shows that had been aired in history.

The funny thing is that most of those shows that you mentioned Tenter probably would do well on Nick at Nite.

partidge family did air on Nick at Nite i watched it on there back then
