The APA Specialty Guidelines for Forensic Psychology, Explained for Attorneys
By David Lombard, PhD: Licensed Psychologist with 30+ years in clinical and forensic practice
Attorneys who work regularly with forensic experts often know the term "specialty guidelines" without necessarily knowing what's in them or why they matter to a case. I want to walk through what the guidelines actually say, because understanding them gives you a concrete way to evaluate any expert's work, mine included.
What the Guidelines Are
The APA Specialty Guidelines for Forensic Psychology, adopted in 2013, set out the professional expectations for psychologists performing forensic work: evaluation, consultation, or testimony connected to a legal proceeding. They aren't binding law, but they function as the field's own statement of what competent, ethical forensic practice looks like, and courts and licensing boards frequently look to them when a psychologist's forensic conduct is questioned.
For attorneys, the guidelines are useful less as background reading and more as a practical checklist: a well-run forensic evaluation should reflect each of the principles below, and a report or expert who doesn't can be a signal worth probing further.
Impartiality Over Advocacy
The guidelines are built around a foundational distinction between forensic practice and the advocacy role attorneys occupy. A forensic psychologist's obligation runs to providing accurate, impartial findings. A forensic psychologist’s obligation is not to advance the position of whichever party retained them. This doesn't mean an expert can't be retained by one side; it means the expert's conclusions should be the same regardless of who's paying, because they're derived from the data, not the retention. If an expert's opinions consistently favor the retaining party across cases, that's worth attorneys examining closely.
Clarity About Role, From the Start
The guidelines call for forensic psychologists to clarify their role to everyone involved before an evaluation begins, including who they're working for, what the evaluation is for, and the limits of confidentiality. This matters practically: a defendant or party who doesn't understand that a forensic evaluation isn't confidential in the way therapy is may not participate accurately, and any ambiguity here can become a basis to challenge the evaluation later.
Competence and Boundaries
The guidelines emphasize that forensic psychologists should only take on evaluations within their actual training and experience, and should be transparent about the limits of their expertise. This is part of why service scope matters: an evaluator who claims expertise across every type of forensic question, without recent, relevant training in each, isn't meeting the standard the field sets for itself.
Avoiding Dual Roles
One of the more consequential provisions addresses the separation between forensic and treatment roles. A psychologist who has provided therapy to a party generally shouldn't also serve as that party's forensic evaluator, because the two relationships create different, sometimes conflicting obligations. A treating clinician is focused on the client's well-being, while a forensic evaluator's obligation is to provide accurate findings for the court. When retaining or opposing an expert, it's reasonable to ask directly whether this kind of dual relationship exists in a given case.
Transparency in Method and Reporting
The guidelines call for forensic reports to make the basis for conclusions traceable: what data was gathered, how it was weighed, and what the limits of the findings are. A report that states conclusions without showing the reasoning behind them falls short of this standard, and it's exactly the kind of gap that becomes a focal point in cross-examination.
What This Means in Practice
None of this is abstract for case preparation. When you're evaluating a report (your own expert's or an opposing one's) these guidelines give you specific, defensible questions to ask: Was the expert's role clarified up front? Is the reasoning traceable to the data? Is there any dual-role conflict? Does the expert's scope of practice match their actual training? A report that holds up well against these questions tends to hold up well in court.
A Closing Thought
Standards like these exist because the stakes in this work are high, and because the people evaluated deserve a process that's rigorous and fair regardless of which side asked for it. I try to hold every evaluation I conduct to this bar, not because a guideline requires it, but because it's the standard I'd want applied if the case were mine.

Frequently Asked Questions
Does a forensic psychologist work for whoever is paying them?
No. Regardless of which party retains or pays for an evaluation, a forensic psychologist's obligation under the APA Specialty Guidelines is to provide accurate, impartial findings based on the data gathered, not to advocate for the retaining party's position.
Can a forensic evaluator also have been the defendant's or party's therapist?
Generally, no. The guidelines call for separating forensic and treatment roles, since a treating clinician's obligation to a client's well-being can conflict with a forensic evaluator's obligation to produce accurate findings for the court.
Are the APA Specialty Guidelines legally binding?
Not in the way a statute is, but courts and licensing boards routinely reference them when a psychologist's forensic conduct is at issue, and they represent the field's own standard for competent practice.
What should an attorney look for in a forensic report to confirm it meets these standards?
Traceable reasoning from data to conclusion, a clear statement of the evaluator's role and any limits on confidentiality, and no indication of a dual relationship (such as prior treatment) between the evaluator and the party.
Who wrote the APA Specialty Guidelines for Forensic Psychology?
They were developed and adopted by the American Psychological Association in 2013, jointly with several forensic psychology and psychology-law organizations, as the field's consensus standard for forensic practice.
