Hi Ashely,
Well done!
You may want to consider narrowing down if there is a particular school experience that you are interested in (e.g., interactions with peers, emotional development, overall adjustment to the school environment etc) . For your second question – defining the meaning of ‘unsupported’ would be helpful in your literature search to keep it focused to your area of research inquiry.
Sidenote: I have not come across any research about RPNs working in school-based settings yet. I am interested to see what emerges from your research. Identifying gaps in research is just as (if not more) important than advancing upon what is currently known. For your second question, there are some HCC literature emerging within the past few years that may be of interest to you. The articles and webinars can be viewed in the library.
