Both the education and indie versions are full versions. The educational version can only be licensed for a year and can only be relicensed a set number of times. The indie version is restricted solely based on income. If the licensee (studio or individual) makes <= 100000 USD per year, then they can use the indie version. There may be slightly different file formats for each.

I remember that at one point there was a Maya LT version which only allowed polygon modelling and some limited animation features, and which didn't allow loading plugins (except a small number of whitelisted plugins). Maybe I confused that with the indie/student license.
