The curriculum model and implementation procedures outlined in this manual for the Developmental Training Program for students with disabilities are based on two trends: the emphasis upon teaching functional skills in the natural environment and the need for educational programs which demonstrate measurability, reportability, and accountability. The manual presents implementation procedures for both the primary-level and the secondary-level student. Initial procedures involve assessing environmental requirements through a parent survey, a community living skills assessment, and a vocational skills evaluation. The same instruments are then completed from the perspective of the student's current skill levels. A discrepancy analysis is conducted to determine which discrepancies can be reduced through skill training, prosthetics, and/or environmental modification. Finally, the individualized education plan (IEP) or individualized transitional plan (ITP) is developed and is evaluated periodically through use of a skill acquisition index. At both the primary and secondary levels, copies of forms are included and a completed IEP/ITP form is offered as an example. (JDD)
