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).
A bachelor's degree is the minimum educational requirement necessary to begin working as a social worker at an entry level. There are two-year associates degree programs in social work, but they primarily serve as a stepping stone to the completion of a four-year BA or BS in social work.
