Preparing for captain builds on what you should already know as a lieutenant. In my experience, the policy subjects are similar, but the questions go into greater depth and the responsibility increases significantly.
You need to demonstrate that you can run a shift, oversee other supervisors, and handle multiple responsibilities correctly.
You also need to understand how much investigative and administrative work can come with the position.
This advice comes from my experience as a captain and attending promotion boards as a candidate. I have not served as a board member.
Demonstrate readiness in your current position
Before applying for captain, establish a record of successfully performing your lieutenant duties.
Show that you can run a shift, conduct the minor investigations assigned to you, and manage several tasks without allowing accuracy or follow-through to slip.
Administration needs to see that you can handle responsibility consistently. One well-managed situation matters, but so does the ordinary work you complete every shift.
If you are struggling to finish assignments correctly or meet deadlines, address those problems before taking on a broader workload.
Study familiar policies in greater depth
In my experience, captain preparation involves much of the same policy material as lieutenant preparation, with more detailed questions.
Continue studying current, authorized policies and the requirements of the position. Ask appropriate supervisors what areas deserve particular attention for the vacancy.
Think about how the policies apply when you are responsible for overseeing lieutenants and sergeants, reviewing situations, and ensuring required follow-up occurs.
Do not assume that knowing enough to perform your current assignment means you have finished preparing. Look for gaps in your understanding and seek clarification.
Board subjects and expectations vary. Use official vacancy instructions and current agency guidance to direct your preparation.
Understand the broader accountability
As a lieutenant, my focus was my shift. When I became a captain, my responsibilities expanded to matters across the unit.
That meant paying attention to what lieutenants and sergeants were doing, whether operations were running correctly, and what needed action beyond an individual incident.
When you are responsible for the operation, you cannot limit your attention to tasks you personally perform. You need to know whether work is being completed correctly by the supervisors and staff you oversee.
The exact scope depends on the assignment. A shift captain and a captain with other unit responsibilities may have different duties, but both need to understand what they are accountable for.
Expect investigations to become a major part of the workload
The volume of investigations was one of my biggest adjustments.
In my agency experience, certain employee disciplinary investigations, staff-and-inmate investigations, and grievance investigations were assigned at the captain level. Those assignments came with specific time limits.
At the same time, the unit still needed to operate correctly.
You may be working through an investigation when an operational issue needs your attention. You then have to manage that issue without losing track of the investigation or its deadline.
Candidates should understand the investigative responsibilities attached to the actual position they are seeking. Assignment authority, procedures, and deadlines must be confirmed through current agency policy.
Build a system you will actually use
I personally have difficulty remembering everything I need to do. I had to find a practical way to keep assignments from being forgotten.
My approach was to begin investigations promptly and complete them as soon as I reasonably could. Procrastinating allowed work to accumulate and made the workload harder to manage.
I also used sticky notes to track what needed to be done and when it was due.
That was my personal reminder system, not a replacement for official records. Any reminders should be handled appropriately, with confidential information kept in authorized systems and locations.
The important point is to have a reliable way to track assignments, deadlines, and unfinished work. Do not depend entirely on remembering everything.
Complete work promptly because the workload can change
My advice is to complete work as soon as you reasonably can—not just investigations, but any assignment.
You might begin a shift with one or two investigations. During that shift, two or three more situations may occur that require your attention and additional work. If you have postponed the original assignments, everything is now competing for your time.
You cannot predict what will happen next. Completing work when you have the opportunity helps you stay prepared for new responsibilities.
That does not mean rushing, skipping required steps, or putting paperwork ahead of an immediate safety need. It means making productive use of the time available and avoiding unnecessary delay.
Procrastination compounds the work you already have. The next assignment may arrive before you expect it.
Accept the administrative side of the rank
Captain assignments can include duties beyond shift operations.
In my experience, those responsibilities have included disciplinary hearings involving officers or inmates, training, and other administrative work assigned by leadership. The duties and authority depend on the position and agency requirements.
A lieutenant considering promotion should learn what those assignments involve before accepting the role.
You may enjoy leading a shift more than completing an investigation. Both may be part of the job you are seeking.
Give yourself time to become proficient
Not many people I know enjoy the investigative workload, but it comes with the position.
My advice is to learn the process and develop a system for completing it. As you gain experience, understand the requirements, and organize the work, it becomes easier to manage.
Ask for instruction when you need it. Seek clarification rather than guessing about a requirement or deadline.
You do not need to pretend that every part of the job appeals to you. You do need to be willing to perform those responsibilities accurately and consistently.
Prepare for the workload behind the rank
A captain candidate should be able to point to dependable performance as a lieutenant: running a shift, handling assigned investigations, managing competing tasks, and following through.
They should also understand that the next position may bring a much larger investigative and administrative workload.
Study the policies, learn the assignment, and consider how you will organize the work. Your preparation needs to extend beyond answering interview questions.
Be ready to oversee the operation, support your supervisors, and complete the work that continues after the immediate situation is over.
