We want to add YOU to this list!
"I am through the entire process and have been promoted to Lieutenant after finishing first in the process.
I have no doubt that the system used by your company allowed me to excel to the top and without it I would not have done as well.
I did not find the program until late in the process and had no idea it would be as in depth as it is.
The program is excellent and I would recommend it to anyone seeking promotion.
-Quoted with Permission
"I am happy to say that my PoliceCareer.com study materials were on point!
"I topped a test taken by 23 other members of my department. I really feel as though the materials I utilized from PoliceCareer.com paved the way for that success.
I am happy to report that I was promoted to Sergeant. I will be recommending your materials to others for the next exam.
Thank you again for an outstanding product!
New Sergeant in Massachusetts
Quoted with permission.
"Just wanted to thank you and your company for the service you provide with the online tests.
This is the second time I have used your company. 5 years ago I used your online tests to help me and I was promoted to Corporal. Several months ago I again enrolled with your company to prepare for the upcoming Sergeants test.
Today I just found out I finished #1 on the Sergeants exam and will be promoted in a few weeks!
I read the books and took the practice exams and scored a 91 on my test and also scored very high on my oral boards! So thanks again!"
Quoted with permission.
"Out of 50 applicants, I scored #1 with the help of your exams.
My partner also purchased the First-line Supervisors exams and he placed #3. Thank you for your assistance!"
New Supervisor in Ohio
Quoted with permission.
"I used your program to prepare for the Sergeant's exam at my department. Your program was very helpful and relevant to the written test I took.
I scored 94% percent on the exam and placed #2 overall among all the candidates.
I was promoted to Sergeant last week and your program was an important part of my success.
"I will absolutely come back to your program when the opportunity to test for Lieutenant arises."
Sergeant Roy V. – California
Quoted with permission.
"I wanted to thank your company for the help testing for both the written and oral promotional exams for lieutenant.
I received a 94 on written and top score on oral boards, and I will promoted to lieutenant!
Please do post my email. It's a great program and will help anyone willing to put the time into studying for the test."
Thanks again Lt. DB, Ohio.
Quoted with permission.
"Sir, I would first like to thank you for the time and effort you put into your product. This was my first promotional test and I had no clue what to expect.
I found every aspect of the online learning and downloadable tests priceless in my preparation. I not only achieved the highest score on our written exam, I beat everyone else by 10+ points.
Going into my oral assessment I knew that I had to score very high due to seniority and the overall weight of the assessment. Utilizing your online video resources for a better oral assessment gave me the edge I needed. Again, I placed first on my oral assessment with an overall 69 out of 75.
I will quote my chief when she gave me the news of my new promotion, "it wasn't even close." I can only thank you for assisting those committed individuals to achieving their goals.

Think in-basket assessments are EASY? They're NOT, and you'll see why.
You don't just read a few phone messages and emails and jot down a few notes.
An in-basket assessment you will undergo for a police promotion contains pages and pages of background material and takes a great deal of concentration and organizational ability, and the ability to work quickly under pressure.
You must also study pages of material such as:
complicated work scenarios
and you must take accurate and detailed
Then you are presented with a detailed scenario along with 10 to 20 in-basket items, all the while a clock is ticking down the time.
Here are some of the dimensions you are
graded on in an in-basket assessment center exercise;
Written communication ability
Verbal communication ability
Planning and organization
Ability to take risks
At the conclusion of the in-basket you are interviewed by the assessors. Your notes are reviewed and discussed with you, and you are judged on:
how quickly and thoroughly you analyze the material and scenarios
how quickly and accurately you complete the many items in the assessment
how accurate and complete your written notes are
how well you verbalize
your analysis, actions, conclusions and responses to the
Finally, your overall rating also takes into account how thorough and knowledgeable you were on your analysis and action on each item, and whether you properly delegated or handled the material.
Do you know that 1/3 - 1/2 of police promotional candidates FAIL their first in-basket assessment because they walk in, unprepared, thinking it will be EASY?
They are then shocked and
surprised at what they find. Don't be one of these candidates.
