The Systematic Curriculum and Instructional Development (SCID) model provides a tested procedure for developing high-quality, low-cost competency-based education and tech prep curriculum and instructional materials. It consists of 5 phases--analysis, design, development, implementation, and evaluation--and 23 components. The analysis phase includes needs, job, and task analyses. In the design phase, the task performance information collected during analysis is used to determine a training approach and develop learning objectives, performance measures, and a training plan. The development phase results in the production of whatever instructional materials, including media, were decided upon during the design phase. In competency- and performance-based programs, the instructional materials typically take the form of competency profiles, learning guides, and modules. The more traditional education and training programs usually produce curriculum guides, courses of study, and lesson plans. Implementation involves putting the education or training program into actual operation. The training is conducted, and learner performance is evaluated. Results of instruction are documented in the form of student and instructor performance records. Summative evaluation data is collected and analyzed; corrective actions are initiated.
