"Teaching elders," as pastors are called in the PCA, are ordianed by their presbyteries, and the policy of accepting ordination from other denominations varies from one presbytery to another. There doesn't seem to be a hard-and-fast rule other than adherence to the Westminster Standards, and any exceptions to the Standards are considered on a case-by-case basis.

Central Florida presbytery used to routinely reciprocate ordination from certain other denoms, but that is no longer typical in this presbytery, though it may still be in others.
