How To Become a Private Investigator in Delaware – Step-by-Step
Let’s take a look at what you need to do to become a private investigator in Delaware.
1. Meet the Personal Requirements
- Must be at least 21 years old.
- This is 25 if you want to open your agency.
- You must not have any felonies on your record. This includes any juvenile crimes that would have gotten you a felony conviction if you had committed them as an adult.
- Must not have committed any theft-related crimes, any drug-related crimes, or any crimes of moral turpitude within seven years.
- You must not have any more than two of these in total throughout your life.
- Must not have a dishonorable discharge from any military branch.
- Must pass all state and federal criminal history checks.
2. Get an Education
Once you are sure you meet the general requirements above, you must get an education.
The state of Delaware does not require a degree to get your license as a private investigator, but having an education beyond your high school diploma or GED will certainly help, especially with agencies that have higher-ranking cases and higher pay and benefits.
There are some, mainly online, programs geared toward private investigation, but there are a few other degrees that can be just as acceptable.
Some degrees you can consider are an AA or BS in Criminal Justice, a BS in Human Services/Criminal Justice, or a Bachelor of Business Administration in Criminal Justice.
3. Find a Position
This may seem to be the incorrect next step, but you can’t get a private investigator license in Delaware unless you have already been hired or guaranteed a position by a private investigating organization.
4. Get a License
Getting a private investigator license requires applying through the Delaware State Police.
You must get a fingerprint check and photo ID and pass both state and national background checks.
Once this is done, you must take a written test and go in front of a committee that will review everything and either issue you a license or deny it.
This is the same committee that has to approve your ability to carry a firearm in general and must give additional approval to carry a concealed weapon.
Acceptance or denial of your application to get a license is based on whether or not you meet all the legal requirements that are in the Delaware Code.
5. Pass A Firearms Course
It may not always be necessary to carry a firearm as a private investigator.
For those who do need to carry one, there are requirements you must meet.
First, candidates must take and pass a 40-hour training course instructed by someone approved by the Delaware State Police.
Upon successful completion of the training, you must also pass a written and practical test.
Anyone having a license to carry must complete three one-shot tests each year to keep that license.
These tests must be scheduled at least three months apart.
All of this is to carry only.
To conceal carry, you must be given additional approval by the licensing committee.
