Professional standards

Anyone working as a therapist or counsellor should be absolutely upfront about their qualifications.
They should make it clear what kind of techniques they use; as well as their position on important issues. Some do precisely this on their website, for all to see.
Of course, anyone worth their salt will also belong to a professional organisation like the Australian Counselling Association.
It describes itself as "a national progressive professional peak association of counsellors and psychotherapists with over 2500 individual members".
Formal qualifications are usually required to join the ACA, however it will make exceptions:
"...ACA is an inclusive association and welcomes membership applications from experienced counsellors who do not meet our educational requirements. ACA is aware that some counsellors do not have a formal recognised qualification in counselling, but do have an extensive history and experience in the counselling field. Many counsellors who first began practising 10 to 20 years ago were not required to complete courses in counselling, if in fact there were any. Counsellors who wish to join ACA and who believe that they may fall into this category can ring ACA for more details about how to apply under this clause. Only counsellors who have received, and can prove through documentary evidence of receiving professional supervision, can apply under this clause..."
There certainly don't seem to be major barriers to membership of the ACA.
If a therapist or counsellor isn't a member, then she might like to explain why not.
On the other hand if she is a member, then she will have no doubt received the Spring 2004 edition of its newsletter, containing the "Draft ACA Position on Repressed/Recovered Memories".
