Yes, I've known 3 at my children's school and they are not at all appropriately trained except in the Scripture Union (qld) dogma. I've no doubt they are paid less than real counsellors, secular or not.
If the first and foremost role of this program was counselling, it would be undertaken by counsellors, not unqualified religious recruiters.
However the first and foremost objective of these people is very clear. While they disguise their website and propagand pretty well these days, you just need to jump onto the wayback machine and look at their older webpages when they were less vigilent. For example:
"SU Qld?s ultimate vision is to bring hope to a young generation through a relationship with Jesus, the Bible and local churches. We do this through school chaplaincy, camping, community outreach and kids at risk programs.
SU exists to work with churches, resourcing and supporting them in their ministry. This partnership provides a strategic alliance for taking advantage of the many opportunities which exist for ministry in primary schools."
Their infiltration of schools is for no other reason than recruitment.
