Researching preschool options

hi everyone! I live in the Houston area, specifically northeast Houston. I want to start researching preschool/private school options for my toddler, specifically a legit place to really go in depth with the rankings. I know I know, Googledotcom is free, but I’m having trouble really narrowing down to a few specific websites that would do the trick. I also wonder if there are preschool/private school finders similar to apartment finders? Thanks in advance.
