The Pennsylvania Advancement School (PAS) opened for its first group of students in October 1967; since then, numerous programs and activities have given the school publicity. In this paper, general information about the school's activities is presented. The paper is divided into three sections: (1) activities that constitute PAS's core program; (2) staff development and consultant services related to the core program; and (3) other activities in which the school or individual staff members participated. The school's effort to effect changes has worked on several levels, from sustained work with students and teachers to dissemination activities such as convention presentations, books and articles, and the hosting of thousands of visitors. Those involved in the program feel hopeful that their efforts will eventually bring about success. (Author/JW)
