There is a lady in Loughrea that did career guidence, consulatancy, she may be in the phone book, or else try the Institute of Guidence counsellors, they should have a list of members, some of whom may engege in private practice.
There are plenty of colleges that do the H Dip in Education or as it is now called the Postgradute in education. There is however competition to get in to do the course, but she is a long way from that stage...
This is a qualification for secondary teaching.
There is also the Hibernian college online course to convert a BA degree to a primary teaching qulaification, again she is a bit away from that stage too.
The guidence counsellor may advise something like an arts degree, if she has no strong preference as to what she would like to do, but she will need to look at the subjects on offer and see if she would be interested in studying them at 3rd level for a few years e.g. French, history, english or whatever.
A business degree is pretty general too, but no more than an Arts degree (or other degrees) further study may be required to get a career out of it.
I suppose start by talking to the career person, maybe give the teacher at her school a ring. Also look up the college websites to get a feel for what is avalable, best of luck.
