How long does an EEOC investigation take?

Most EEOC investigations take about 10 months. That's the EEOC's own average across all charge types. In 2023, the average was closer to 11 months. If your case goes to mediation instead, it usually wraps up in under 3 months.

Those numbers come straight from the EEOC, not from estimates. But "average" means some cases finish faster and some drag out much longer. The actual timeline for your charge depends on the facts, the office handling it, and how fast both sides respond.

The timeline step by step

Here's what happens after you file a charge of discrimination, and roughly when.

Days 1-10: Employer notification. The EEOC sends a notice of the charge to your employer within 10 days of your filing date. The employer gets access to the EEOC's Respondent Portal, where they can read the charge and submit a response.

Days 10-90: Mediation offer. The EEOC may offer both sides mediation. If you and the employer agree, a neutral mediator tries to help you reach a settlement. Mediation is voluntary for both sides, and it's the fastest path. Successful mediations typically resolve in 2 to 3 months. In FY 2024, the EEOC resolved 8,543 private-sector mediations, recovering $243.2 million for charging parties.

Months 1-3: Investigation begins. If mediation doesn't happen or fails, the EEOC assigns an investigator. The investigator usually asks the employer for a written response (called a "Position Statement") explaining their side. You get a copy and can upload a rebuttal through the EEOC Public Portal within 30 days.

Months 3-10: Fact gathering. The investigator collects evidence. This can include:

• Requests for documents (personnel files, policies, performance reviews)
• On-site visits to the workplace
• Interviews with witnesses, supervisors, and coworkers
• Review of your evidence and any response you filed

If the employer stonewalls, the EEOC has the power to issue an administrative subpoena to force production of documents or testimony.

After investigation: Determination. Once the investigator finishes, the EEOC makes a call:

• No reasonable cause. The EEOC can't determine that discrimination likely happened. You get a Dismissal and Notice of Rights. You have 90 days from receiving that notice to file a lawsuit in federal court.
• Reasonable cause. The EEOC believes discrimination probably occurred. Both sides get a Letter of Determination, and the EEOC tries conciliation, an informal process to negotiate a resolution. If conciliation fails, the EEOC can file a lawsuit on your behalf or decide not to. If it decides not to, you get a Notice of Right to Sue and 90 days to file your own lawsuit.

What speeds it up or slows it down

Faster:

• Simple facts and clear documentation
• Both sides cooperate with the investigator
• Mediation is accepted and works
• Smaller employer with fewer witnesses

Slower:

• Multiple allegations or a pattern of behavior
• Either side delays responding to requests
• The employer refuses to cooperate (subpoenas take time)
• The local EEOC office has a heavy caseload

In FY 2024, the EEOC received 88,531 new discrimination charges, a 9.2% increase over the year before. They ended the year with 52,080 charges still pending. That backlog affects how fast any individual case moves.

The 180-day rule

For charges filed under Title VII (race, color, religion, sex, national origin) or the ADA (disability), you must give the EEOC at least 180 days to investigate before you can ask for a Right to Sue letter. In some cases the EEOC will agree to issue one earlier, but they don't have to.

Once you receive the Right to Sue, the clock starts: you have 90 days to file in federal court. Miss that window and your case is over, regardless of its merits.

Different rules apply under other laws:

• Age Discrimination in Employment Act (ADEA): You can file a lawsuit 60 days after your charge is filed. You don't need a Right to Sue letter from the EEOC.
• Equal Pay Act: You can sue within 2 years of receiving your last discriminatory paycheck (3 years if the violation was willful). No Right to Sue letter needed.

What you can do while you wait

You're not powerless during the investigation. Here's what helps your case:

Document everything. Keep records of any new incidents, changes in treatment at work, or retaliation. If your employer retaliates against you for filing the charge, that's a separate violation you can add to your case (called "amending" your charge).

Use the EEOC Public Portal. You can check your case status, upload supporting documents, review the employer's position statement, and file your rebuttal, all online.

Keep your contact info current. If the EEOC can't reach you, your charge can stall or get closed.

Talk to a lawyer if you haven't already. The EEOC investigation is administrative, not a lawsuit. Having an attorney doesn't slow the process, and many employment lawyers work on contingency (they only get paid if you win).

What the EEOC recovers when it finds discrimination

The numbers are real. In FY 2024, the EEOC recovered almost $700 million for approximately 21,000 victims of employment discrimination. That included over $469 million through mediation, conciliation, and settlements in the private sector, and more than $190 million for federal employees. The agency also filed 111 new lawsuits and resolved 132, winning or settling 97% of them.
