The two hour delay is scheduled for Teacher Professional Development.
Teachers are lifelong learners. In fact, ongoing education is a requirement for teachers of every public school level, from kindergarten through 12th grade. Known as professional development, this education -- usually in the form of workshops, seminars and training courses -- helps teachers stay up to date with new trends and learn fresh strategies, techniques and methods for classroom challenges. The overriding idea behind professional development is that increased knowledge helps teachers improve student achievement. That's because professional development focuses on what each teacher needs to fine-tune his or her classroom practice.
