OUR SCORES ARE TRUTHFUL AND NOT EXAGGERATED!!


​Our Testimonials Speak for Themselves:

​"There are several promotional schools to choose from and I had narrowed it down to two.
After much thought and talking with other police officers, I decided to go with DelBagno School
for Police/PERI. It was definitely a difficult process, you really need to put in time, not only at
the school but also studying at home. Special thank you to Chief Rotonda who really took the
time to help me in focusing in on the important details. He even offered one-on-one
instruction. My score was a .98! Well above my competition who went to the other school.
Very happy with my choice. I will be back for my LT promotion."


"If you are looking for a promotional school, this is it. I scored #1 on my written exam for LT, but
I knew my weak spot was the oral board with the State Chiefs. The material I studied was on
target, but the oral presentations with Chief Rotonda was what really helped. He gave me the
confidence to sit before the panel of Chiefs with ease.

Thank you DelBagno School for my Lieutenant promotion!"


"From day one, I knew Del Bagno/PERI was the right choice.  The study material was very thorough and helped me to

feel well prepared for the testing process.  Throughout my studying, each of the staff made it clear that I needed

to continue to read at home as well to truly understand and retain the material.  I listened intently to all of the

advice that came my way and tried to absorb all I could from the eye-opening lectures. Needless to say, the

coaching truly paid off!  I received the top score on the Sergeant's written exam with a 97!  

Thank you, Del Bagno School for Police!"


"​I had previously attended a different school for my first promotional exam and did not score as
high as I had hoped. I studied very hard and went to all the assigned classes. When I did not
make the Sergeant promotion the first time, I decided to attend The DelBagno School for my
second chance at promotion. I’m very glad I did. Not only did I receive the top score of .97, but
I was very impressed with the amount of effort DelBagno puts into their course. So glad I
decided to change schools. Thank you to all the instructors!"
