Northern Arizona University's Arizona Career Ladder Research & Evaluation Project for teachers implements a procedure for rewarding teachers based on performance levels rather than on years of teaching experience and college credits. Research data is collected each spring, analyzed and fed back to the districts for improvement of key program components. This document is a data report representing descriptive and analytical results from a questionnaire administered to ten Phase I and Phase II pilot test districts. Data are presented in the following tables: (1) data return rate by districts and year; (2) demographics for the 1987 data cycle; (3) frequencies and percentages of selected demographics for 1986 and 1987; (4) frequencies and percentages stratified on teacher career ladder participation and years of teaching experience; (5) means and change scores in perceptions of career ladder concepts; (6) composite mean perceptions for career ladder subscales by districts; (7,8,9,10 and 11) response profile of percentage agreement with specific career ladder concepts based on comparisons among selected demographics; (12) organizational climate subscales stratified within selected demographic characteristics; and (13) educator perceptions of organizational climate items by percentage agreement/disagreement and total mean scores for 1986, 1987 data cycles. A brief evaluation summary and implications is presented for each table. Also included is the Executive Summary presented to the Arizona Joint Legislative Committee on Career Ladders. Thirteen data tables, a letter to professional educators, demographic information sheet and a perception assessment scale conclude this document. (JD)
