Hi 1st time mummy,
I would look for an apprenticeship in your local council, that's where you work alongside study, and thats the most affordable option if you can get on one.
Apply to several places and find where you fit best. Different unis have different strengths. Bigger research unis might have a heavier academic focus, more resources, but the smaller unis might have more pastoral support available.
Have a passion for social justice and be prepared to work hard. Anyone studying a professional degree has not only the academic study to consider, but about 50% of the learning will be on placement and skills development.
Familiarise yourself with BASW code of ethics, and PCF for entry level to university.
Read community care to give yourself an idea of some of the current issues in social work, think about your own emotional resilience and what you have to bring to social work.
Have a really solid understanding of what social work is. I've interviewed hundreds of people applying for social work training, and those that walk in thinking it's about helping people, or don't know the difference between social work and nursing, get advised to do some more research and reapply the following year. The more research you do, the more chance you can reassure an interview panel you understand the challenges and reality of Social Work.
Overall be yourself and go for it!
