Phoenix, Arizona, has experienced the impact of a nationwide trend toward an increased teenage birthrate, with nearly 1,500 births to teenage mothers in 1980. To serve the special needs of teenage mothers, the Phoenix Union High School offers an alternative education program, Cyesis, for pregnant and parenting teens. Data from the center's year-end report showed that 228 students were served during the 1980-81 school year. Most students made academic progress, and almost 75% of the students completed the school year or graduated. Many students received assistance from social service agencies as well as physicians. Surveys of former and current students and staff revealed positive opinions about the Cyesis Center. Surveys of helping physicians and agencies revealed a need for dissemination of more information about the program. Data tables (N=25) are provided throughout the document to illustrate the program evaluation findings. (Author/JAC)
