Is there data showing differences in outcomes between procedures performed by ABA certified people and ones who aren’t? – Spark Testing Environment

There is no reliable database that reports outcomes. The problem is each organization collects its own statistics. For instance, the ABA and the ABPM both have databases showing the numbers of procedures done by their members. The ABA Doctors can also be members in more than one society, and may provide data to more than one group. So, comparing statistics is difficult.
