There seems to be a shortage of so many providers.  This situation may well become worse as more people gain access to healthcare insurance.  This statement is to strongly endorse any efforts that may already be underway, namely:

Develope a greater array of levels of certifications, especially at lower levels, to facilitate easier access to the fields. Require appropriate supervision and perhaps continuing training, whether onsite or online or separately.

In general, at middle levels, provide more autonomy and responsibility.
