A hospital is a health care institution providing patient treatment with specialized medical and nursing staff and medical equipment.
If you do not want to give up your paid job, you can undertake the social work degree on a part time basis. The previous qualifications necessary to become a social worker were the Certificate in Social Service (CSS), the Certificate of Qualification in Social Work (CQSW) and Diploma in Social Work (DipSW).
For an entry-level job, you will need at least a bachelor's degree in social work (BSW), but you may be able to get a job with a degree in psychology or sociology. Some jobs require a Master's Degree in Social Work (MSW), and if you want a career as a clinical social worker, this advanced degree is required.
