GRAMMAR
Qualification is usually plural. Qualifications are all the examination passes and skills you need to do a particular job : Academic qualifications (NOT qualification) are not necessary to do this job.
When qualification is used in the singular form in British English, it means 'a degree, a certificate, a diploma etc' : a qualification in business studies. Speakers of American English usually mention the specific name of the degree, diploma etc they are talking about, e.g. high school diploma, college degree, teaching certificate etc.
!! Do not say 'study a qualification'. Say study for a qualification.
