Workplace Investigator Certification: The Options Compared

Certificate, Certification, Credential, License: The Terms

No general law requires an in-house HR professional to hold a certification to investigate complaints for their own employer. What employers, courts, and agencies look at is whether the investigator was trained, impartial, and thorough. Training is evidence of the first.

Investigating for hire is different. Some states regulate who may conduct investigations for compensation. California's Private Investigator Act, for example, defines the regulated activity broadly and exempts attorneys performing their duties as attorneys and persons employed exclusively and regularly by one employer in connection with that employer's affairs. No training certificate substitutes for a license where one is required. Check licensing rules in each state where you plan to work for clients. We cover this in in-house investigator or outside investigator.

Workplace Investigator Certification Options at a Glance

Details below reflect what each provider's site showed in early October 2026. Fees, dates, and requirements change; confirm with the provider.

SHRM Workplace Investigations Specialty Credential

SHRM describes this credential as a package: its Leading Workplace Investigations instructor-led program and two eLearning courses, titled Managing Bias in a Workplace Investigation and Competent Workplace Investigation Interviews. Participants complete all components and pass a final knowledge assessment to earn the credential, which comes with a certificate of achievement and a digital badge. SHRM states that successful completion awards 13.5 PDCs.

SHRM's general information on specialty credentials says there are no prerequisites and that a specialty credential does not expire or require PDCs to maintain. The same page notes that policies can vary by program. Check SHRM for the current price, total hours, and whether the no-expiration policy applies to this credential.

Fits best if: you want the SHRM name on your profile, you already hold or are pursuing SHRM-CP or SHRM-SCP and want PDCs from the same body, and you are comfortable with a mix of instructor-led and self-paced learning.

Consider something else if: you want several days of supervised practice with an instructor, or you need a program aimed at full-time or external investigators.

Association of Workplace Investigators (AWI)

The Association of Workplace Investigators is a professional association for people who conduct workplace investigations, and it runs a Training Institute for investigators. Check AWI's site for its current description of membership and mission.

AWI itself uses the word certificate. Those who complete the Institute and pass its assessments may use the designation AWI-CH, which stands for AWI Certificate Holder. Confirm current details directly with AWI, including the Institute's format, assessment areas, testing deadlines, accreditation, fees, membership requirements, eligibility, and delivery options. Because the program tests interviewing and report writing and not only recall, it is a demanding option.

Fits best if: investigations are most or all of your job, you investigate for clients, or you want a designation issued by an association of investigators and backed by graded assessments.

Consider something else if: investigations are one part of a generalist role and you need the full process, forms, and practice in a shorter block, or the time commitment is more than your employer will support.

HRTrainingCenter Internal Investigations Certificate Program

To be clear about what this is: our Internal Investigations Certificate Program is a certificate program. You attend, you complete the training, and you receive a certificate showing that you completed it. It is not an accredited certification and it is not a license.

What the course page describes:

• Length and format. Three consecutive days, offered in person at scheduled venues and by live video conference, with on-site delivery available for groups.
• Method. A step-by-step investigation process applied through interactive exercises and realistic workplace scenarios, covering complaint evaluation, interviewing complainants and witnesses, reluctant or hostile witnesses, evidence, retaliation and harassment investigations, potential FMLA abuse, and report writing.
• Materials. A participant workbook, sample investigation forms and templates, witness interview guides, documentation and chain-of-custody forms, case studies, and checklists.
• Credits. 18 SHRM and HRCI recertification credits. See how these work on our SHRM and HRCI recertification credits page.
• Online companion. Attendees also receive access to the online Internal Investigations Training and Certification Program. Check that program's page for the designation offered and its requirements.

There is also an advanced course for experienced investigators; see Basic or Advanced investigations program to choose between them.

Fits best if: you are an HR generalist, HR manager, employee relations specialist, or compliance professional who needs to run investigations competently for your own employer, and you learn best by practicing with an instructor over consecutive days.

Consider something else if: you specifically need a credential issued by SHRM or a designation recognized among external investigators.

Other Routes

• University and law school continuing education. Several universities and bar-related providers offer investigation courses. Quality varies with the instructor; look at the syllabus and who teaches it.
• General HR certifications. PHR, SPHR, SHRM-CP, and SHRM-SCP cover employee relations broadly but are not investigation credentials. See HR Certifications Compared and PHR vs. SHRM-CP vs. Specialized HR Certifications.
• Law firm and employer-run training. Useful for aligning with your own counsel's preferences, usually without a portable credential.

A broader list is in our roundup of Top Workplace Investigation Training Programs.

How to Choose

Ask five questions.

1. Who needs to recognize it? Your employer, a future employer, clients, or opposing counsel reviewing your background in a deposition? Name recognition differs by audience.
2. Does it include practice? Interviewing and report writing are skills. Programs that make you do them, and give feedback, change behavior more than programs that only explain them.
3. Is there an assessment, and of what? A knowledge quiz tests recall. A graded interview or report tests performance.
4. What do you take back to work? Templates, forms, and a documented process have value on the first Monday back.
5. What does it count toward? If you hold a SHRM or HRCI certification, check the recertification credit.

Format matters as well. If you are weighing travel against a live online session, see In-Person vs. Virtual HR Training. If you need budget approval, our article on making the case to your employer for investigations training includes a memo outline.

Frequently Asked Questions

The Bottom Line

Pick the option that matches your role. External and full-time investigators should look closely at AWI. HR professionals who want a SHRM-branded credential have one. HR professionals who need to run sound investigations for their own employer, with templates and three days of guided practice, are the audience for the Internal Investigations Certificate Program.
