A practical hands-on guide, Preparing a Professional Portfolio: A School Administrator's Guide, offers a dynamic, developmental and standards-based approach to professional portfolio development for educational leadership. This guide will facilitate the reader's development and completion of a meaningful portfolio while also presenting enhanced explanations of each of the ISLLC Standards so that the reader can find deeper meaning in the standards and implement them in authentic ways. This guide fills a serious void with regard to information and guidelines on portfolios and standards-based licensing requirements for both building level and district level administrators. It can be used as a supplemental guide in administrative courses or as a text for independent study or internship courses. This guide is also useful for practicing school leaders pursuing licensure renewal and for aspiring leaders building job-placement credentials.
