Many thanks for your patience, I am pleased to be able to continue assisting with your query now. First of all, I am sorry to hear about this situation and any associated issues.
The results of the assessment would amount to personal data under data protection regulations.
The GDPR, the flagship law dealing with data protection, providers data subjects (that is you), with certain rights. One of these is the right to erasure, or the right to be forgotten:
“The data subject shall have the right to obtain from the controller the erasure of personal data concerning him or her without undue delay and the controller shall have the obligation to erase personal data without undue delay where one of the following grounds applies:
the personal data are no longer necessary in relation to the purposes for which they were collected or otherwise processed;”
Your argument here is that once the application process has completed, it is no longer relevant and as you won’t be applying again, they will no longer be needing that information to be stored.
