MUA accreditations

From MUA website, they claim they have following: WHO,IMED,FAIMER,ECFMG,ACCM

I have seen other schools have CAAM-HP.. mua doesnt seem to have this (saba doesnt either, i think..).. so is this of any significance? if so, why dont they have it? is it something to be concerned about?

accreditations are the most important thing to look for when looking for a caribmedschool, right?

Thanks in advance,
Ricky
