The CHP academy is actively training and has two classes in house now. The senior class is nearing graduation - about five or six more weeks. The junior class is in its fifth or sixth week of training.
You can track their training and see photos of the classes on this link about the academy. Just page down to "Read experiences..." and click on either 08-III or 08-IV.
The next scheduled class begins in January or February.
