I don't know what area in CA, you're in, but I'm here in Los Angeles where the titles vary, right along with the educational requirements. Now, I can only point you to certain schools and you can inquire about their requirements and find out more about the titles that they refer to as the 911 dispatchers and the rest you have to do yourself. POST, stands for Peace Officer Standards and Training or in other areas, or unlike the other poster here, it stood for something else. Either way, that's why I said when you inquire from a particular educational institution, they'll tell you-every agency's methods is different. 911 Dispatchers, the title that they call this, when taking the civil service or servant exam, is Police Services Representative. The educational dept., which are many, but one that sticks out is the Rio Hondo College in Whittier, CA. This educational institution is the "tops," in my book for here in the Southern CA region. Now, I can't recall what their website link is, since it's been years ago when I attended their school. You can Google it and see what you come up with. They have on-line courses, which is why I'd recommend this school to you. They have police, corrections, ambulance, dispatchers and other titles, with their own unique programs-check it out. As for the POST training, it depends on the agency and where they go to get their training. Again, I went to a community college (West Los Angeles College in Culver City, CA), with other law enforcement professionals and the training varied. I'm not going to give you some misinformation, because it could've changed since then. Anyhow, Google this information to get the recent website links for these institutions. If you need further help, I'll be more than happy to assist you with your request. Good luck in this situation.
