* The specific diploma: A diploma from a recognized institution in a relevant field is generally accepted. However, the level of the diploma matters. Some diplomas are equivalent to a bachelor's degree, while others are more like vocational certifications. A diploma equivalent to an associate's degree (2 years) might require additional coursework before admission to a Master's program.
* The specific Master's program: Universities have different admission requirements. Some might require a bachelor's degree, while others might accept a relevant diploma with sufficient work experience or additional bridging courses. Check the specific entry requirements of the Master's program you are interested in.
* The country and institution: Admission requirements vary across countries and institutions. What's acceptable in one country or university might not be in another.
* Work experience: Some Master's programs might consider significant relevant work experience in lieu of a bachelor's degree, particularly if the diploma is from a vocational training program.
In short, while a diploma isn't automatically equivalent to a bachelor's degree for Master's admission, it's possible. Always check the specific admission requirements of the Master's program you're interested in. You might need to contact the university's admissions office directly to clarify if your diploma qualifies.
