Is there some website that rates small language schools?

[Crispy]

I am seeking jobs at a couple of language schools in various places in Japan, most of them seem pretty small and I have no idea whether they are well-respected or not. Is there some page in Japanese or English that reviews language schools from around the country?

Two schools we are talking about in particular are CES in Kitami, Hokkaido, and ACE in Kangawa, Shikoku. I know next to nothing about either of these, but they are among the only schools who will take someone with no teaching experience (other than the Big Three), so I am a little suspicious...
