Certificate:

A certificate is earned by a student after taking a series of courses in a particular subject. Students often earn certificates to get a step ahead in the professional field of their interest, and certificates may be offered in similar programs leading to degrees.

Diploma:

Diplomas are similar to certificates, and they're often awarded through community or technical schools. For instance, a diploma of nursing is offered as an alternative to an associate's degree or bachelor's degree. This diploma program is only offered at hospitals with specialty programs that provide training.
