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).
Each state has its own requirements for becoming a licensed social worker, so it is important that you are familiar with the criteria in the state where you wish to work. For the working professional who has already completed an undergraduate degree, earning a Master of Social Work (MSW) degree is the best way to work toward changing careers.
