Is your RSA Statement of Attainment valid in the ACT?

Yes.

As of 1st July 2017, valid interstate RSA certificates are acceptable in the ACT, as long as the course was completed through a registered/approved training organisation.
This means that it is no longer a requirement for a person who holds a valid interstate RSA qualification, to also obtain an ACT approved RSA qualification.

Kindly visit the following URL and check version R26 onwards (after 1 July 2017).
