One very common trend in a lot of crossfit athletes especially at our box, is that many of us can clean a lot more than we can jerk which shows an imbalance in our Olympic lifting.

Here is a great video with behind the neck technique, as well as some other great training ideas.
Exercise:Behind the neck Split or power jerk 12x1 ( total sets, add weight every set and find a good heavy weight you can hit with good technique consistently.)
