The main indicator of the quality of a school, or the validity of the programs and degrees it offers, is whether or not the school is accredited. The article below details accreditation in the US and in Canada, and how you can tell whether a school is or is not accredited.
According to the Department of State, in the US, accreditation is voluntary, so an institution can choose whether it wishes to be regionally or nationally accredited – or not accredited at all.

Students at institutions that do not hold some form of recognized regional or national accreditation are likely to encounter problems in obtaining scholarships, transferring credits, having their credentials recognized by employers, etc.
The Secretary of Education is legally required to publish a list of nationally recognized accrediting agencies that the Secretary has determined to be able to evaluate and accredit schools and training programs.
