who knows if ONLINE degrees are fake?

They are not necessarily fake, however, the degree or credits earned may not transfer to another place and some places will not recognize the college attended even if you could prove it was you.

i got a degree in early childhood education then i went to the preschool district to look for a job what would they say?

Well, it depends. Some may accept it and offer you better pay with it, while others may acknowledge that you have it and you get a job but they may not give you better pay. Best thing to do would be to call the place you are looking to work for and ask them if they would accept or acknowledge it.

There are different kids of online schools.

There are fully accredited schools that grant respected degrees. Many long established universities now have online programs.

There are dubious schools that are unaccredited or are accredited by an official sounding but bogus accreditation organization (often the school itself). Some of these schools will give credit for self-study or “life experience” so long as you still pay them.

There are outfits that make no pretense and sell diplomas.
