Student Teachers are the bomb!

As I sit here today and reflect on my latest awesome experience with a student teacher I can't help but think that they are an underutilized resource in our schools today.  In my district there is an actual restriction on how many quarters you may work with a student teacher.  In a time of increased collaboration and the ever increasing push for interventions and small grouping I feel like student teachers are a valuable asset that needs to be used!  What do you think?
