Whether or not a certificate or diploma is better for a student to obtain depends on the student's existing education, personal goals and career requirements. Certificate programs focus on a specific area or skill while a diploma allows students to gain a broad range of knowledge concerning a field.
Those people who already have a diploma or are interested in learning a narrow skill set should consider a certificate. Certificate programs are much shorter than diploma programs. Workers can get a certificate to make them more attractive for specialized career opportunities.
Diploma programs are better for those interested in a well-rounded education. They are able to provide workers with a wider range of opportunities than a certificate.
