The purpose of the Chapter 1 Early Childhood Education Program in Portland Public Schools is to provide disadvantaged children the experiences needed to ameliorate the disadvantages resulting from their circumstances. This evaluation report of the 1989-90 school year concludes the program's 18th year of operation. The preschool program consisted of two classes per day in three classrooms in one building. Program capacity was 120 students. Students participated in group activities in the classrooms; visited the library weekly; and were taken outdoors to participate in large motor skills development activities. Student skills were evaluated by teachers in the spring and fall. The percentage of students who demonstrated complete mastery of particular skills in the spring evaluation ranged from 4 to 87 percent for language skills, 5 to 78 percent for numerical concepts, 3 to 93 percent for small motor skills, 13 to 53 percent for social development, 45 to 77 percent for art and music, 6 to 95 percent for large motor skills, and 1 to 93 percent for personal welfare skills. Due to inconsistent results caused by changing conditions of program operation, follow-up evaluation studies have been discontinued since 1987, and attention has turned to finding ways to improve the program. An appendix presents the Preschool Student Evaluation Form. (BC)
