Research and evaluation activities have gradually evolved from the selection of an improvement and evaluation model, as well as data collection using an attitudinal survey and application of case study procedures along with focus group interviews, to the preparation of summary documents and specific policy recommendations. This document presents models of evaluation, assessment, and profiling that have emerged from the activities and findings of the Career Ladders Research and Evaluation Project. The project, in its 5th year of indepth study of 15 pilot-test school districts, has produced extensive data on specific interrelated components within school systems. The three resultant assessment models and profiling procedures can be applied to any school system (or organization) that has identified the essential interrelated components for reaching functional goals. The models--"Interrelated Components of Program Support and Focus for Effecting Change and Reform in Education,""Assessment Model for Projected District Readiness Levels," and "District Readiness Profile of Strengths and Weaknessess"--provide for individual diversities of readiness levels and allow sufficient time for change within unique systems.
