Under the terms of the student grant scheme, grant assistance is awarded to students on full-time courses who meet the prescribed conditions of funding including those which relate to nationality, residency, approved course, previous academic attainment and means.
With regard to the specific application, I have been advised by Student Universal Support Ireland (SUSI) that the position in this case is that the applicant previously holds a Level 8 qualification and is therefore not eligible for the student grant.
I would encourage the student in question to contact the access office and disability office in the institution they attend to consider what supports may be available including under the student assistance fund and the fund for students with a disability,
