If you are trying to decide if you want to schedule an 8 hour course or a 4 hour course in Personal and Professional Resilience for your department, there are a couple differences to consider. The 8 hour courses are considered the "full" course. In the 8 hour courses, there are more POST board objectives covered and they are covered in more detail.
The 4 hour courses are designed for departments who need to fit a couple of trainings into one day and are limited to 4 hours due to time/budget constraints. With the 4 hour course, you will still be getting lots of good information, tips and tools, just condensed and edited to fit the time frame that might work best for you.
