Just filled out the Cao form and im a bot confussed

Okay, what universities have you applied to?

Have you checked each university/college and gone through what documentation is required of them?

I know the application process can be different for nursing but most universities/colleges request some or all of the following for mature application:

• copies of your Junior/Leaving cert. results
  
• copies of any post secondary school courses you have completed -PLC, FETAC
  
• Copies of 3rd level results/certificates
  
• personal statement
  
• CV
  
• letters of recommendation

Edit: I found this on page 12 of the CAO HANDBOOK:

Note:
Mature applicants applying for Graduate Medicine
and/or mature code Nursing/Midwifery courses only
do not need to supply the information outlined in the
opposite column. subjects, levels and any results to date.

So you probably don't need to worry about any additional documents.
