IQAS is to Canada what UGC is to India. It is an authority that helps certify degrees issued by foreign authorities to make sure that they meet Canadian standards.
IQAS is typically helpful for employers, educational institutions and professional licensing bodies as it helps them determine whether their foreign applicants meet the standards that are required of them.
It is also helpful for potential immigrants who are looking for further education and employment in Canada. It helps them gauge their own education and skills.
