IA investigations are the most scrutinized process in any department — and among the most regulated. Department policy, city and county rules, state law, and officer rights statutes all govern how these investigations must be conducted. Every decision is watched — by the officer, the union, administration, the courts, and the community. Get the process wrong and everyone pays for it. Get it right and the process does what it is supposed to do: find the truth, apply the rules fairly, and reach a conclusion that holds.
Third Degree Training founded the first private-sector Internal Affairs training in the Western States in 2013. We built the original course and have refined it every year since, working with IA investigators, command staff, union leaders, and officer representatives across the United States. We know this landscape from every angle — because we train every angle.
What separates this course is the legal day. We partner with each state’s top police defense law firm or SME attorney to dedicate a full day to current case law — POBR, Garrity, Lybarger, officer rights, parallel investigations, and defensible findings. No other IA training in the country does this. It is the day that changes what every person at the table understands about how these investigations must be conducted.
We are not advocates for administration or for the union. We are advocates for process done right — thorough investigations, protected rights, and conclusions that hold up to scrutiny from every direction.
Four Sides of the Table: The Officer. Administration. The Union. The Attorney. IA investigations are highly regulated — department policy, city and county rules, and state law all require process to be followed precisely. When all four sides understand the same standards and the same law, the process works the way it is supposed to — less friction, stronger investigations, protected rights, defensible conclusions.
This is a three-day, 24-hour course — the most comprehensive IA training available in the Western States. Here’s how it is structured:
IA investigations are the departments solve culture applied to the institution itself. Not solving crimes — solving the barriers that undermine trust, accountability, and the department’s ability to function at its best. A well-run IA process protects the good officer from a bad complaint, holds the officer who crossed the line accountable, and shows the community that the department polices itself with the same rigor it brings to everything else. That process has to be correct. That’s what this course teaches
This course is built for everyone who touches an IA investigation — on any side of the table. Law enforcement, union leadership, legal counsel, private sector investigators, and government oversight all operate within the same regulatory framework. All four sides benefit from training on the same standards at the same time.
Law Enforcement — Investigators & Command
Private Sector IA Investigators
Union & Legal
Government & Oversight
Note on Private Sector Investigators:
Private investigators and law firm investigators conducting or supporting IA-style investigations face the same regulatory obligations as sworn personnel — often without the institutional training that sworn investigators receive. This course gives them the same foundation.

The legal aspect of IA Investigations is extremely important in these investigations. I learned a lot from this portion of the class. Excellent class, instructor and quality of information.

What I liked best about this class was the case study the Instructor provided. It was very obvious just how qualified the Instructor is, so each lesson taught was thoroughly explained. The Instructor was also able to answer every question. Very enjoyable course. After learning the process of an IA investigation, it was very helpful to hear from an attorney with many years of experience who represents LE officers in both criminal and administration investigations. After hearing from the Instructor, his portion of the class became paramount to understanding IA investigations from opposing sides.
