I just got approved to attend CISAC (35L) and I wanted to know what should I expect entering this MOS?

I’ve been a CI Agent/Tech since 1988 and I was an instructor at the Reserve Course in Ft Devens for a while. Expect to provide presentations/briefings, learn to take notes during an investigation (VERY detailed notes) and then write a very detailed report (this is where most fail), you will learn to “meet” with people, debrief them and give them instructions, and you will also learn some surveillance techniques. If your writing skills are below par, take a remedial writing course - if you can't write at at least a 12th grade level you will have a very hard time. This is likely the hardest school you will ever attend. You will need to learn time management and not to stress, teamwork and maintaining a professional demeanor. Don’t stress too much – it will only hurt you but this is not a “gentlemen’s course.” Also, be prepared to deploy a lot. Best of luck to you!

I can't agree more with the comments in this thread. As a former instructor of CISAC, best advice I can give you is to listen to the instructors. We know what we're doing....listen, take notes, and be loose! Don't stress! This course is hard; however, you will do just fine. Work on your writing and briefing skills.

One of the biggest parts of the job is talking to people. Every part of your job will involve talking whether you are briefing a group or an individual, conducting an interview , or advising someone. You have to be able to speak clearly, professionally, and with confidence. Reading up on public speaking tips would be a good place to start.
