I do not have time to go to these workshops. You never schedule these activities when I am available. Is professional development really required?

Yes, it really is! However, professional development is designed to support you. Many activities you already plan to do or are doing fit into the self-designed categories.  A list of self-designed activities is available in the current PD Workshops and Events Booklet and on the Annual Program page of the PD web site.  There are also online activities and DVDs and videos available to you.
