So from this (see link) it appears soon you will no longer have to a masters to earn a DETC doctorate. I did not know they had this policy. Distance Education and Training Council: Proposed Changes and Public Comment
Yes, there are even a few RA schools that offer this. It's either Walden, UoP or Capella (can't remember which) that does not require a masters to get into their doctorate of psychology. It's a really long program though, and I think you in essence do all the master's work along the way.
In the end it is all still really the same number of credit. 81 if you onlyt have a BS or 51 if you have a masters to earn a PhD.
Straight to Doctorate There are even B&M schools that will allow this transition for psychology. My wife's cousin just finished her doctorate here in Southern California last week from an RA school and she was straight from a bachelors.
I believe the majority of US doctoral programs allow people with a Bachelor's to enter, typically regarding it as a combined Master's/Doctorate, and typically awarding the Master's at some point along the path to the Doctorate (such as when passing the qualifying exams and being admitted to candidacy). (My wife, although she already has a Master's, did not need one for admission to her Ph.D. program at Vanderbilt . . . nor did she need a second one, which came 'automatically' after passing the quals, making her a "MA MA.")
It appears Fielding only requires a BS/BA from a Regionally accredited school: Fielding Graduate University
