Qualifications from Drishane Convent?

I wonder if anyone can help with the following question we received today, likely about Drishane Convent School:

“Hello, a cousin of mine studied at a residential post primary college in or near Millstreet in the early 1950’s. It might have been called Drishane Castle. What qualifications might the pupils have got in Domestic Science or kindred subjects? I would be grateful for any information to put in her obituary that will be needed any day.
Many thanks, Mary”

If you know, please leave a comment below, or send an email to <contact@millstreet.ie>, and we will forward the answers.
