本研究旨在探討校長工作價值觀、重要他人支持、自我效能感對其工作選擇的影響情形，探討不同重要變項理論內涵、現況與變項之間關係，進而建構及驗證其互動模式，並依研究結果提出建議。 本研究先進行文獻探討，作為架構研究的理論基礎，並以100名校長為預試樣本，分析預試結果以形成正式問卷，再以404名之校長為正式問卷施測樣本，問卷回收整理後分別以描述統計、t考驗、相關分析、變異數分析、多元逐步迴歸分析及線性結構模式分析探討；之後，根據調查結果研擬訪談題綱，實地訪談10名現職校長以瞭解造成差異的原因。本研究之主要研究發現如下： 一、國民中小學校長在工作價值觀、重要他人支持、自我效能感與工作選擇的得分現況屬於中高程度。 二、擔任校長的年資、性別、學校區域等背景變項，在校長工作價值觀量表的得分有差異情形存在。 三、學校類別、總服務年資、擔任校長的年資、性別、學校區域等背景變項，在重要他人支持量表的得分有差異情形存在。 四、總服務年資、擔任校長的年資、性別、學校區域等背景變項，在校長自我效能感量表的得分有差異情形存在。 五、學校類別、擔任校長的年資、性別、學校區域等背景變項，在校長工作選擇量表的得分有差異情形存在。 六、工作價值觀、重要他人支持、自我效能感與校長工作選擇具高度相關。 七、工作價值觀、重要他人支持、自我效能感對校長工作選擇有顯著預測力。 八、工作價值觀、重要他人支持、自我效能感對校長工作選擇有顯著影響力。 九、校長自我效能感對其工作選擇的影響力最大，重要他人支持次之，工作價值觀的影響力最小。 最後，根據研究結果提出相關建議，以供教育行政機關、校長培育中心、現職校長以及未來研究之參考。 / The purpose of this study was to investigate the impact of work values, significant other’s support, and self-efficacy for principal’s job choice.

The purpose of literature analysis was aimed to explore the relationship of work values, significant other support, self-efficacy, and job choice. The pilot study was included 100 subjects. The sample was included 404 principals. The data was analyzed by descriptive statistics, t-test, correlation, ANOVA, multiple regression and LISREL model. The interview was conducted according to the analyzed results. The major findings were: 1.The principal’s scores on work value, significant other’s support, self-efficacy and job choice were moderately high. 2.Years of principalship, gender, and districts could make significant differences on principal’s work values 3.The levels of schools, in-service years, years of principalship, gender, and districts could make differences on significant other’s support. 4.In-service years, years of principalship, gender, and districts could make differences on principal’s self-efficacy. 5.The level of schools, years of principalship, gender, and districts could make differences on principal’s job choice. 6.There was highly positive correlation among principal’s work values, significant other’s support, self-efficacy, and job choice 7.The principal’s job choice could be predicted by work values, significant other’s support, self-efficacy. 8.The principal’s job choice could be affected by work values, significant other’s support, self-efficacy. 9.Principal’s self-efficacy was the strongest indicator for job choice, significant other’s support was the second one, and work values were the smallest one.
