Painter here. I went to art college, and whilst the experience overall was positive, and I made lots of friends, I didn't learn much art; I learnt to talk and write about it.
Sadly, most art courses now have nothing to do with art; they are art theory courses. Many tutors don't know how to paint; for the last 40 years, painting was seen as unfashionable, and conceptual art was pushed heavily, totally deskilling generations of prospective painters.
To keep the courses running and themselves in jobs, the people running the courses must apply academic criteria per the university model to keep the funding going. She will have to justify every mark she makes on the canvas, research it, reflect on it, and write about it to the point that it could compromise her talent and, depending on her style, any spontaneity to make a good painting.
If your daughter wants to be a portrait painter, I would look at the Royal Society of Portrait Painters website and some of the artists she likes; look at their bios to see where they trained and work backwards from there. Another thought is to contact the painters directly and ask if they run courses or ask to train with them, similar to the atelier method.
With any good portrait painter, you need drawing as your foundation. If she is looking at traditional portraiture, consider The Lyme Academy of Fine Arts. Jordan Sokol is the art director, an exceptional painter -

Best of luck. I did many sensible jobs, but in the end, art won through. The world needs really good art more than ever x
