This is the final evaluation report for Boston's Title I Early Childhood Jackson-Mann Developmental Program (1980-81). The Early Childhood component serves about 1000 4-year-olds (kindergarten I) and 5-year-olds (kindergarten II) in an effort to raise the level of educational achievement among children identified as needing special assistance. The children receive daily individualized or small group instruction from a Title I paraprofessional, as a supplement to class work, in the classroom setting. The Jackson-Mann component provides highly individualized instruction to 20 hearing-impaired 3- to 6-year-olds integrated with children with normal hearing from the morning kindergarten classes. In the regular Title I program, standardized test score gains were significant for kindergarten children, but the majority of them did not meet the criterion of mastering 80 percent of performamce objectives. In Jackson-Mann, hearing students in kindergarten I made significant gains, though scores in kindergarten II dropped. The majority of hearing-impaired students accomplished at least 80 percent of the performance objectives. Overall, participants were satisfied with administrative support, curriculum and performance objectives, communication, orientation and inservice workshops, materials (rated very highly), and facilities, and dissatisfied with parental involvement.
